TESS Giants Transiting Giants V -- Two hot Jupiters orbiting red-giant hosts
Filipe Pereira, Samuel K. Grunblatt, Angelica Psaridi +24
In this work we present the discovery and confirmation of two hot Jupiters orbiting red-giant stars, TOI-4377 b and TOI-4551 b, observed by TESS in the southern ecliptic hemisphere…

Marc Hon, Daniel Huber, Nicholas Z. Rui +39
When main-sequence stars expand into red giants, they are expected to engulf close-in planets. Until now, the absence of planets with short orbital periods around post-expansion, c…
Revisiting the Red-giant Branch Hosts KOI-3886 and Draconis. Detailed Asteroseismic Modeling and Consolidated Stellar Parameters
Tiago L. Campante, Tanda Li, J. M. Joel Ong +23
Asteroseismology is playing an increasingly important role in the characterization of red-giant host stars and their planetary systems. Here, we conduct detailed asteroseismic mode…
