A systematic validation of hot Neptunes in TESS data
Christian Magliano, Giovanni Covone, Richa Dobal +26
We statistically validated a sample of hot Neptune candidates applying a two-step vetting technique using DAVE and TRICERATOPS. We performed a systematic validation of 250 transit-…
TESS Giants Transiting Giants III: An eccentric warm Jupiter supports a period-eccentricity relation for giant planets transiting evolved stars
Samuel K. Grunblatt, Nicholas Saunders, Ashley Chontos +27
The fate of planets around rapidly evolving stars is not well understood. Previous studies have suggested that relative to the main sequence population, planets transiting evolved…
A transmission spectrum of the sub-Earth planet L98-59~b in 1.1-1.7 m
Mario Damiano, Renyu Hu, Thomas Barclay +20
With the increasing number of planets discovered by TESS, the atmospheric characterization of small exoplanets is accelerating. L98-59 is a M-dwarf hosting a multi-planet system, a…
TESS discovery of a super-Earth and two sub-Neptunes orbiting the bright, nearby, Sun-like star HD 22946
Luca Cacciapuoti, Laura Inno, Giovanni Covone +51
We report the Transiting Exoplanet Survey Satellite (TESS) discovery of a three-planet system around the bright Sun-like star HD~22946(V=8.3 mag),also known as TIC~100990000, locat…
A Population of Dipper Stars from the Transiting Exoplanet Survey Satellite Mission
Benjamin K. Capistrant, Melinda Soares-Furtado, Andrew Vanderburg +12
Dipper stars are a classification of young stellar objects that exhibit dimming variability in their light curves, dropping in brightness by 10-50%, likely induced by occultations…
TIC 114936199: A Quadruple Star System with a 12-day Outer Orbit Eclipse
Brian P. Powell, Saul A. Rappaport, Tamás Borkovits +19
We report the discovery with TESS of a remarkable quadruple star system with a 2+1+1 configuration. The two unique characteristics of this system are that (i) the inner eclipsing b…
