TOI-5205b: A Short-period Jovian Planet Transiting a Mid-M Dwarf

The Astronomical Journal, 2023
We present the discovery of TOI-5205b, a transiting Jovian planet orbiting a solar metallicity M4V star, which was discovered using Transiting Exoplanet Survey Satellite photometry and then confirmed using a combination of precise radial velocities ...

Orbital migration and the frequency of giant planet formation [PDF]

, 2002
We present a statistical study of the post-formation migration of giant planets in a range of initial disk conditions. For given initial conditions we model the evolution of giant planet orbits under the influence of disk, stellar, and mass loss torques.

TESS-Keck Survey. XIV. Two Giant Exoplanets from the Distant Giants Survey

The Astronomical Journal, 2023
We present the Distant Giants Survey, a three-year radial velocity campaign to measure P(DG∣CS), the conditional occurrence of distant giant planets (DG; M _p ∼ 0.3–13 M _J , P > 1 yr) in systems hosting a close-in small planet (CS; R _p < 10 R _⊕ ). For

Global Models of Planet Formation and Evolution [PDF]

, 2014
Despite the increase in observational data on exoplanets, the processes that lead to the formation of planets are still not well understood. But thanks to the high number of known exoplanets, it is now possible to look at them as a population that puts ...

Gaia search for stellar companions of TESS Objects of Interest

Astronomische Nachrichten, Volume 341, Issue 10, Page 996-1030, December 2020., 2020
The first results of a new survey, which explores the second data release of the ESA‐Gaia mission, are reported in order to search for stellar companions of (Community) TESS Objects of Interest and to characterize their properties. In total, 193 binary and 15 hierarchical triple star systems are presented, detected among 1,391 target stars, which are ...

Rotation Periods, Inclinations, and Obliquities of Cool Stars Hosting Directly Imaged Substellar Companions: Spin–Orbit Misalignments Are Common

The Astronomical Journal, 2023
The orientation between a star’s spin axis and a planet’s orbital plane provides valuable information about the system’s formation and dynamical history. For non-transiting planets at wide separations, true stellar obliquities are challenging to measure,

LMDZ6A: The Atmospheric Component of the IPSL Climate Model With Improved and Better Tuned Physics

Journal of Advances in Modeling Earth Systems, Volume 12, Issue 7, July 2020., 2020
Abstract This study presents the version of the LMDZ global atmospheric model used as the atmospheric component of the Institut Pierre Simon Laplace coupled model (IPSL‐CM6A‐LR) to contribute to the 6th phase of the international Coupled Model Intercomparison Project (CMIP6).

Tidal Decay and Stable Roche-Lobe Overflow of Short-Period Gaseous Exoplanets [PDF]

, 2016
Many gaseous exoplanets in short-period orbits are on the verge or are in the process of Roche-lobe overflow (RLO). Moreover, orbital stability analysis shows tides can drive many hot Jupiters to spiral inevitably toward their host stars.

Formation of giant planets around stars with various masses [PDF]

, 2006
We examine the predictions of the core accretion - gas capture model concerning the efficiency of planet formation around stars with various masses. First, we follow the evolution of gas and solids from the moment when all solids are in the form of small

TOI-1859b: A 64 Day Warm Jupiter on an Eccentric and Misaligned Orbit

The Astrophysical Journal Letters, 2023
Warm Jupiters are close-in giant planets with relatively large planet–star separations (i.e., 10 < a / R _⋆ < 100). Given their weak tidal interactions with their host stars, measurements of stellar obliquity may be used to probe the initial obliquity ...
