Magnetic activities on two single-lined RS Canum Venaticorum binaries IM Pegasi and Geminorum
Dongtao Cao, Shenghong Gu, F. Grundahl +1
We present the study on continuous high-resolution spectroscopic observations of two long-period single-lined RS Canum Venaticorum (RS CVn) binary stars IM Pegasi (IM Peg) and …
Unresolved Rossby and gravity modes in 214 A and F stars showing rotational modulation
Andreea I. Henriksen, Victoria Antoci, Hideyuki Saio +9
Here we report an ensemble study of 214 A- and F-type stars observed by \textit{Kepler}, exhibiting the so-called \textit{hump and spike} periodic signal, explained by Rossby modes…
FX UMa: A New Heartbeat Binary System with Linear and Non-linear Tidal Oscillations and delta Sct Pulsations
Kun Wang, Anbing Ren, Mads Fredslund Andersen +3
We present a detailed analysis of an eclipsing double-lined binary FX UMa based on TESS photometry and newly acquired spectroscopic observations. The radial velocities and atmosphe…
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…
Precise radial velocities of giant stars XV. Mysterious nearly periodic radial velocity variations in the eccentric binary Cygni
Paul Heeren, Sabine Reffert, Trifon Trifonov +10
Using the Hamilton Echelle Spectrograph at Lick Observatory, we have obtained precise radial velocities (RVs) of a sample of 373 G- and K-giant stars over more than 12 years, leadi…
Asteroseismic masses of four evolved planet-hosting stars using SONG and TESS: resolving the retired A-star mass controversy
Sai Prathyusha Malla, Dennis Stello, Daniel Huber +12
The study of planet occurrence as a function of stellar mass is important for a better understanding of planet formation. Estimating stellar mass, especially in the red giant regim…
