The Possible Tidal Demise of Kepler's First Planetary System
Shreyas Vissapragada, Ashley Chontos, Michael Greklek-McKeon +6
We present evidence of tidally-driven inspiral in the Kepler-1658 (KOI-4) system, which consists of a giant planet (1.1, 5.9) orbiting an evolved host s…
Radial velocity confirmation of a hot super-Neptune discovered by TESS with a warm Saturn-mass companion
E. Knudstrup, D. Gandolfi, G. Nowak +59
We report the discovery and confirmation of the planetary system TOI-1288. This late G dwarf harbours two planets: TOI-1288 b and TOI-1288 c. We combine TESS space-borne and ground…
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…
Three low-mass companions around aged stars discovered by TESS
Zitao Lin, Tianjun Gan, Sharon X. Wang +42
We report the discovery of three transiting low-mass companions to aged stars: a brown dwarf (TOI-2336b) and two objects near the hydrogen burning mass limit (TOI-1608b and TOI-252…
Spinning up the Surface: Evidence for Planetary Engulfment or Unexpected Angular Momentum Transport?
Jamie Tayar, Facundo D. Moyano, Melinda Soares-Furtado +15
In this paper, we report the potential detection of a nonmonotonic radial rotation profile in a low-mass lower-luminosity giant star. For most low- and intermediate-mass stars, the…
Constraining the Planet Occurrence Rate around Halo Stars of Potentially Extragalactic Origin
Stephanie Yoshida, Samuel Grunblatt, Adrian Price-Whelan
The search for planets orbiting other stars has recently expanded to include stars from galaxies outside the Milky Way. With the TESS and Gaia surveys, photometric and kinematic in…
