A Preponderance of Perpendicular Planets
Simon H. Albrecht, Marcus L. Marcussen, Joshua N. Winn +2
Observing the Rossiter-McLaughlin effect during a planetary transit allows the determination of the angle between the sky projections of the star's spin axis and the planet's o…
TOI-1431b/MASCARA-5b: A Highly Irradiated Ultra-Hot Jupiter Orbiting One of the Hottest & Brightest Known Exoplanet Host Stars
Brett Christopher Addison, Emil Knudstrup, Ian Wong +70
We present the discovery of a highly irradiated and moderately inflated ultra-hot Jupiter, TOI-1431b/MASCARA-5b (HD 201033b), first detected by NASA's Transiting Exoplanet Survey S…
Hot planets around cool stars -- two short-period mini-Neptunes transiting the late K-dwarf TOI-1260
I. Y. Georgieva, C. M. Persson, O. Barragán +56
We present the discovery and characterization of two sub-Neptunes in close orbits, as well as a tentative outer planet of a similar size, orbiting TOI-1260 - a low metallicity K6V…
Temperature and Distance Dependence of Tidal Circularization in Close Binaries: A Catalog of Eclipsing Binaries in the Southern Hemisphere Observed by the TESS Satellite
Anders B. Justesen, Simon Albrecht
Tidal forces are important for understanding how close binary stars and compact exoplanetary systems form and evolve. However, tides are difficult to model and significant uncertai…
A backward-spinning star with two coplanar planets
Maria Hjorth, Simon Albrecht, Teruyuki Hirano +5
It is widely assumed that a star and its protoplanetary disk are initially aligned, with the stellar equator parallel to the disk plane. When observations reveal a misalignment bet…
Masses and compositions of three small planets orbiting the nearby M dwarf L231-32 (TOI-270) and the M dwarf radius valley
Vincent Van Eylen, N. Astudillo-Defru, X. Bonfils +69
We report on precise Doppler measurements of L231-32 (TOI-270), a nearby M dwarf ( pc, M, R), which hosts three transiting p…
