Secular orbital dynamics of the innermost exoplanet of the $$\upsilon $$-Andromedæ system [PDF]
Celestial Mechanics and Dynamical Astronomy, 2023 AbstractWe introduce a quasi-periodic restricted Hamiltonian to describe the secular motion of a small-mass planet in a multi-planetary system. In particular, we refer to the motion of $$\upsilon $$ υ -And $$\textbf{b}$$ b which is the innermost planet among those discovered in the ...

Dynamics of Colombo’s Top: Generating Exoplanet Obliquities from Planet–Disk Interactions [PDF]
The Astrophysical Journal, 2020 Abstract Large planetary spin–orbit misalignments (obliquities) may strongly influence atmospheric circulation and tidal heating in a planet. A promising avenue to generate obliquities is via spin–orbit resonances, where the spin and orbital precession frequencies of a planet cross each other as the system evolves in time.

The impact of Ozone on Earth-like exoplanet climate dynamics: the case of Proxima Centauri b [PDF]
Monthly notices of the Royal Astronomical SocietyThe emergence of the James Webb Space Telescope and the development of other advanced observatories (e.g. ELTs, LIFE and HWO) marks a pivotal moment in the quest to characterize the atmospheres of Earth-like exoplanets. Motivated by these advancements,

The influence of coronal mass ejections on the gas dynamics of the atmosphere of a “hot Jupiter” exoplanet [PDF]
Astronomy reports (Print), 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.

Proceedings of the National Academy of Sciences of the United States of America, 2023 Significance Using a fully coupled, three-dimensional atmospheric chemistry-radiation-dynamics model, we demonstrate that the atmospheric composition of terrestrial exoplanets can be self-oscillatory under nonvarying external forcings. This finding could

Tidal dynamics of transiting exoplanets [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractTransits give us the mass, radius, and orbital properties of the planet, all of which inform dynamical theories. Two properties of the hot Jupiters suggest they had a dramatic origin via tidal damping from high eccentricity. First, the tidally circularized planets (in the 1-4 day pile-up) lie along a relation or boundary in the mass-period ...

Tidal synchronization of close-in satellites and exoplanets: II. Spin dynamics and extension to Mercury and exoplanet host stars [PDF]
Celestial Mechanics and Dynamical Astronomy, 2015 This paper deals with the application of the creep tide theory (Ferraz-Mello, CeMDA 116, 109, 2013) to the rotation of close-in satellites, Mercury, close-in exoplanets and their host stars. The solutions show two extreme cases: close-in giant gaseous planets, with fast relaxation (low viscosity) and satellites and Earth-like planets, with slow ...

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 ...
