This book was released on 2006-01-16 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers in this volume cover a wide range of subjects covering the most recent developments in Celestial Mechanics from the theoretical point of nonlinear dynamical systems to the application to real problems. We emphasize the papers on the formation of planetary systems, their stability and also the problem of habitable zones in extrasolar planetary systems. A special topic is the stability of Trojans in our planetary system, where more and more realistic dynamical models are used to explain their complex motions: besides the important contribution from the theoretical point of view, the results of several numerical experiments unraveled the structure of the stable zone around the librations points. This volume will be of interest to astronomers and mathematicians interested in Hamiltonian mechanics and in the dynamics of planetary systems.

Book Synopsis Tracing Dynamical Evolution of Planetary Systems by : Jiayin Dong
Download or read book Tracing Dynamical Evolution of Planetary Systems written by Jiayin Dong and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamical imprints on planetary systems, such as planetary spin rate, orbital eccentricity, mutual inclination, and stellar obliquity provide direct evidence by which we can compare theoretical models of planet formation against observations. In this dissertation, I capitalized on these dynamical tracers to identify and model critical physical processes during multiple stages of planet formation and evolution. First, planetary spin is a fingerprint of planet formation and reflects how a forming gas giant planet interacts with its circumplanetary disk. Using hydrodynamic simulations, I showed there is a maximum spin rate a gas giant planet can spin up through its circumplanetary disk. In contrast to the classical view of planets accreting until their rotation reaches the breakup periods, planets can at most reach 60--80% of their breakup rates before their gaseous envelope accretion becomes decretion, accompanying solutions where angular momentum is being lost. The work complemented the existing giant planet accretion models and predicted the maximum spin rate on forming giant planets. Second, I used debris disks as an indirect probe of young planetary systems where strong stellar activity challenges planetary characterization. Using analytical studies and N-body simulations, I showed in most systems, debris disk features such as warps, eccentric rings, gaps, and azimuthal asymmetries are dominated by a single planet and can be used to interpret the young planet's properties. However, in a few system configurations where the detected planet is not the dominant planet of the disk features, the interpretation of the planet's properties can be flawed by order of magnitudes. Lastly, orbital eccentricity and stellar obliquity are powerful tracers to the mature planet's dynamical history. I focused on Warm Jupiters, which are giant planets with orbital periods between 8 to 200 days. The origin of Warm Jupiters was not clear and the investigation was limited by the small sample size. Using NASA's Transiting Exoplanet Survey Satellite (TESS) and ground-based observing facilities, I discovered and characterized Warm Jupiters in TESS Full-Frame Image data. I led the discovery of TOI-3362b, a super eccentric Warm Jupiter suggesting the high-eccentricity tidal migration origin, and TOI-1268b, a young circular Warm Jupiter aligned with its host star suggesting an in-situ formation or disk migration origin. From both individual targets and the population study of the catalog on the eccentricity distribution study using hierarchical Bayesian modeling, I showed Warm Jupiters are likely from multiple origins.

This book was released on 2008-06-12 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dense stellar systems lie at the interface between dynamics, stellar evolution, and galaxy formation, and they provide us with an ideal laboratory to understand many different aspects of these important fields as well as to explore the interplay between them. The complete study of dense stellar systems is a very challenging task which requires the collaboration and the exchange of ideas of astronomers and physicists with observational and theoretical expertise in galactic and extra-galactic astronomy, stellar dynamics, hydrodynamics, stellar evolution, as well as knowledge of many aspects of computational physics. IAU Symposium 246 brought together experts in all these areas to cover the broad field of dense stellar systems with particular emphasis on the interplay between them and on the comparison between observations and simulations. This volume provides a complete review of the most recent studies in this topical research.

This book was released on 2017 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dynamical interactions of our Solar System have been studied in depth since Isaac Newton recognized that the planets may not be stable to each other's gravitational perturbations. Recently, the discovery of exoplanet systems, including approximately a thousand planet candidates in systems of more than two bodies, has opened an extremely vast and diverse laboratory for planetary dynamics. In this dissertation, I describe techniques for measuring the dynamical, post-Keplerian interactions of planetary systems. Such signals often require numerical N-body analysis and photodynamic techniques combined with Bayesian statistics to correctly determine the properties of the planetary systems causing them. By simultaneously fitting the entire lightcurve data set at once, I am able to extract low signal-to-noise effects such as the resonance dynamics of a very faint system (Kepler-223), the slow orbital precession of a giant planet system (Kepler-108), and transit timing variations among very small and low mass planets (Kepler-444). I use these analyses to gain physical insight into the system's history, such as Kepler-108's potentially chaotic, violent past. Kepler-223's present structure indicates a migration origin for at least some close-in, sub-Neptune planets, which I explore in terms of tidal dissipation, smooth and stochastic migration, and secular evolution. I also analyze circumbinary systems including the newly discovered KIC 10753734. Taken together, these results provide insight into planetary formation in a broad array of environments for planet from compact sub-Neptune systems to Jupiters and circumbinary planets.

Download or read book Solar System Dynamics written by Carl D. Murray and published by Cambridge University Press. This book was released on 2000-02-13 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Solar System is a complex and fascinating dynamical system. This is the first textbook to describe comprehensively the dynamical features of the Solar System and to provide students with all the mathematical tools and physical models they need to understand how it works. It is a benchmark publication in the field of planetary dynamics and destined to become a classic. Clearly written and well illustrated, Solar System Dynamics shows how a basic knowledge of the two- and three-body problems and perturbation theory can be combined to understand features as diverse as the tidal heating of Jupiter's moon Io, the origin of the Kirkwood gaps in the asteroid belt, and the radial structure of Saturn's rings. Problems at the end of each chapter and a free Internet Mathematica® software package are provided. Solar System Dynamics provides an authoritative textbook for courses on planetary dynamics and celestial mechanics. It also equips students with the mathematical tools to tackle broader courses on dynamics, dynamical systems, applications of chaos theory and non-linear dynamics.
Book Synopsis Formation, Evolution, and Dynamics of Young Solar Systems by : Martin Pessah
Download or read book Formation, Evolution, and Dynamics of Young Solar Systems written by Martin Pessah and published by Springer. This book was released on 2017-12-04 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book's interdisciplinary scope aims at bridging various communities: 1) cosmochemists, who study meteoritic samples from our own solar system, 2) (sub-) millimetre astronomers, who measure the distribution of dust and gas of star-forming regions and planet-forming discs, 3) disc modellers, who describe the complex photo-chemical structure of parametric discs to fit these to observation, 4) computational astrophysicists, who attempt to decipher the dynamical structure of magnetised gaseous discs, and the effects the resulting internal structure has on the aerodynamic re-distribution of embedded solids, 5) theoreticians in planet formation theory, who aim to piece it all together eventually arriving at a coherent holistic picture of the architectures of planetary systems discovered by 6) the exoplanet observers, who provide us with unprecedented samples of exoplanet worlds. Combining these diverse fields the book sheds light onto the riddles that research on planet formation is currently confronted with, and paves the way for a comprehensive understanding of the formation, evolution, and dynamics of young solar systems.

Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in radial velocity and transit surveys have led to a large increase in the number of detected multi-planet systems, indicating that such systems are common in the Galaxy. These multi-planet systems bear little resemblance to our own Solar System: most of the detected exo-planets are Super-Earths or Mini-Neptunes, and have periods shorter than 200 days. The discovery of these systems have challenged conventional notions of planetary dynamics, and exposed fertile areas of research. In this thesis, I present three papers on the dynamical evolution of multi-planet systems in the context of findings by Kepler and similar missions. (1) I study the dynamical effects of eccentric and/or misaligned external companions on inner multi-planet systems. (2) I study the effect of hard scatterings between outer giant planets on inner multi-planet systems, and derive a mathematical model to compute the distribution of the final system parameters. (3) Turning my attention inward, I propose a low-eccentricity migration mechanism to explain the origins of ultra-short-period planets, an unusual subset of Kepler planets whose origins are presently not well understood.
