Wide-Orbit Exoplanet Demographics [PDF]

open access: yes, 2019
Astro2020 Science White paper 2019International audienceThe Kepler, K2 and TESS transit surveys are revolutionizing our understanding of planets orbiting close to their host stars and our understanding of exoplanet systems in general, but there remains a

Exoplanet imaging data challenge: benchmarking the various image processing methods for exoplanet detection [PDF]

open access: yes, 2020
The Exoplanet Imaging Data Challenge is a community-wide effort meant to offer a platform for a fair and common comparison of image processing methods designed for exoplanet direct detection. For this purpose, it gathers on a dedicated repository (Zenodo)

VaTEST. II. Statistical Validation of 11 TESS-detected Exoplanets Orbiting K-type Stars

open access: yesThe Astronomical Journal, 2023
NASA’s Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission designed to find transiting exoplanets orbiting nearby bright stars. It has identified more than 329 transiting exoplanets, and almost 6000 candidates remain unvalidated. In

Testing exoplanet evaporation with multitransiting systems [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
ABSTRACT The photoevaporation model is one of the leading explanations for the evolution of small, close-in planets and the origin of the radius-valley. However, without planet mass measurements, it is challenging to test the photoevaporation scenario. Even if masses are available for individual planets, the host star’s unknown EUV/X-ray

Follow-Up and Validation of K2 and TESS Planetary Systems With Keck NIRC2 Adaptive Optics Imaging

open access: yesFrontiers in Astronomy and Space Sciences, 2021
High resolution imaging (HRI) is a critical part of the transiting exoplanet follow-up and validation process. HRI allows previously unresolved stellar companions and background blends to be resolved, vetting false positive signals and improving the ...

Stellar companions to exoplanet host stars: A Lucky Imaging survey of transiting exoplanet systems [PDF]

open access: yes, 2016
About half of all nearby stars are part of a binary or multiple star system, yet little is known about how multiplicity affects the formation and subsequent evolution of planetary systems. For instance, stellar companions may promote the inward migration of massive planets into very short orbits or cause misalignment between the planetary orbit and the

DYNAMIC EVOLUTION EXOPLANET SYSTEMS, MOVING IN ORBITAL RESONANCES WITH THE ACCOUNT OF SECULAR PERTURBATION FROM N BODIES

open access: yesOdessa Astronomical Publications, 2017
Equations of exoplanet's motion connected with orbital Lindblad resonances with the account of secular terms caused by gravitational non-resonant perturbation are derived. Qualitative researches of orbital evolution modeling exoplanet systems are carried
