LavAtmos: An open‐source chemical equilibrium vaporization code for lava worlds

open access: yesMeteoritics &Planetary Science, Volume 58, Issue 8, Page 1149-1161, August 2023., 2023
Abstract To date, over 500 short‐period rocky planets with equilibrium temperatures above 1500 K have been discovered. Such planets are expected to support magma oceans, providing a direct interface between the interior and the atmosphere. This provides a unique opportunity to gain insight into their interior compositions through atmospheric ...

A Revised Exoplanet Yield from the Transiting Exoplanet Survey Satellite (TESS) [PDF]

open access: yes, 2018
The Transiting Exoplanet Survey Satellite (TESS) has a goal of detecting small planets orbiting stars bright enough for mass determination via ground-based radial velocity observations.

Identifying Exoplanets with Deep Learning. V. Improved Light-curve Classification for TESS Full-frame Image Observations

open access: yesThe Astronomical Journal, 2023
The TESS mission produces a large amount of time series data, only a small fraction of which contain detectable exoplanetary transit signals.

Understanding the Planetary Formation and Evolution in Star Clusters (UPiC). I. Evidence of Hot Giant Exoplanets Formation Timescales

open access: yesThe Astronomical Journal, 2023
Planets in young star clusters could shed light on planet formation and evolution since star clusters can provide accurate age estimation. However, the number of transiting planets detected in clusters was only ∼30, too small for statistical analysis ...

Scaling K2. VI. Reduced Small-planet Occurrence in High-galactic-amplitude Stars

open access: yesThe Astronomical Journal, 2023
In this study, we performed a homogeneous analysis of the planets around FGK dwarf stars observed by the Kepler and K2 missions, providing spectroscopic parameters for 310 K2 targets —including 239 Scaling K2 hosts—observed with Keck/HIRES.

Revised Stellar Properties of Kepler Targets for the Q1-17 (DR25) Transit Detection Run [PDF]

open access: yes, 2017
The determination of exoplanet properties and occurrence rates using Kepler data critically depends on our knowledge of the fundamental properties (such as temperature, radius and mass) of the observed stars. We present revised stellar properties for 197,

Prospects from TESS and Gaia to Constrain the Flatness of Planetary Systems

open access: yesThe Astronomical Journal, 2023
The mutual inclination between planets orbiting the same star provides key information to understand the formation and evolution of multiplanet systems.
