The Influence of Coronal Mass Ejections on the Gas Dynamics of the Atmosphere of a "Hot~Jupiter" Exoplanet [PDF]
Astronomy Reports, Volume 60, Issue 2, pp.183-192, 2016, 2016 The results of three-dimensional numerical simulations of the gas dynamics of the atmosphere of a "hot Jupiter" exoplanet during the passage of a coronal mass ejection (CME) from the central star are presented. These computations assumed the parameters for the stellar wind and the CME to be typical of the solar values.

Predicted Number, Multiplicity, and Orbital Dynamics of TESS M-dwarf Exoplanets [PDF]
The Astronomical Journal, 2019 Abstract We present a study of the M-dwarf exoplanetary systems forthcoming from NASA’s TESS mission. While the mission’s footprint is too complex to be characterized by a single detection completeness, we extract ensemble completeness functions that recover the planet detections from previous work for stars between 3200 and 4000 K.

Dynamics of co-orbital exoplanets in a first-order resonance chain with tidal dissipation [PDF]
Astronomy & Astrophysics, 2022 Co-orbital planets (in a 1: 1 mean motion resonance) can be formed within a Laplace resonance chain. We develop a secular model tc study the dynamics of the resonance chain p: p : p + 1, where the co-orbital pair is in a first-order mean motion resonance with the outermost third planet.

Effects of Bulk Composition on the Atmospheric Dynamics on Close-in Exoplanets [PDF]
The Astrophysical Journal, 2017 Abstract Super Earths and mini Neptunes likely have a wide range of atmospheric compositions, ranging from low molecular mass atmospheres of H2 to higher molecular atmospheres of water, CO2, N2, or other species. Here we systematically investigate the effects of atmospheric bulk compositions on temperature and wind distributions for ...

The Dynamics-Based Approach to Studying Terrestrial Exoplanets
, 2007 One of the great quests of astronomy is to obtain the spectrum of a terrestrial planet orbiting within the habitable zone of its star, and the dominant challenge in doing so is to isolate the light of the planet from that of the star. Dynamics-based methods separate these signals temporally, whereas imaging techniques do so spatially.

Evidence for Low-level Dynamical Excitation in Near-resonant Exoplanet Systems
The Astronomical Journal, 2023 The geometries of near-resonant planetary systems offer a relatively pristine window into the initial conditions of exoplanet systems. Given that near-resonant systems have likely experienced minimal dynamical disruptions, the spin–orbit orientations of ...

ATMOSPHERIC DYNAMICS OF TERRESTRIAL EXOPLANETS OVER A WIDE RANGE OF ORBITAL AND ATMOSPHERIC PARAMETERS [PDF]
The Astrophysical Journal, 2015 The recent discoveries of terrestrial exoplanets and super-Earths extending over a broad range of orbital and physical parameters suggest that these planets will span a wide range of climatic regimes. Characterization of the atmospheres of warm super-Earths has already begun and will be extended to smaller and more distant planets over the coming ...

Dynamics of Small Solar System Bodies and Exoplanets [PDF]
, 2010 The Gaia space mission to be operated in early 2012 by the European Space Agency (ESA), will make a huge step in our knowledge of the Sun's neighbor-hood, up to the Magellanic clouds. Somewhat closer, Gaia will also provide ma jor improvements in the science of asteroids, and more generally to our Solar System, either directly or indirectly.

Mass-dependent dynamics of terrestrial exoplanets using ab initio mineral properties [PDF]
Icarus, 2018 We present new modelling results for the internal structure and convective dynamics of large terrestrial (rocky) exoplanets. By going out to 20 Earth masses our results show that pressure and temperature can reach several Terapascal (TPa) and 10000 K respectively in the silicate mantle of these planets.
