Global asteroseismology of 19,000 red giants in the TESS Continuous Viewing Zones
K. R. Sreenivas, Timothy R. Bedding, Daniel Huber +5
TESS (Transiting Exoplanet Survey Satellite) has produced long-term photometry for millions of stars across the sky. In this work, we present an asteroseismic catalogue of 19,151 r…
The highest mass Kepler red giants -- II. Spectroscopic parameters, the amplitude-activity relation, and unexpected halo orbits
Courtney L. Crawford, Yaguang Li, Daniel Huber +11
The high-mass (M2 \Msolar{}) Kepler red giant stars are less well-studied than their lower-mass counterparts. In the previous article, we presented a sample of 48 high-mass Kepl…
Photometric activity cycles in fast-rotating stars: Revisiting the reality of stellar activity cycle branches
Deepak Chahal, Devika Kamath, Richard de Grijs +2
We aim to detect activity cycles in young main-sequence stars, analogous to the 11-year solar cycle, using combined photometric survey data. This research will enhance our understa…
Population synthesis of hot subdwarf B stars with COMPAS: on the observed Galactic population
Nicolás Rodríguez-Segovia, Ashley J. Ruiter
Hot subdwarf B stars (sdBs) are helium-burning stars with thin hydrogen-rich envelopes. Their most widely accepted formation channels involve binary evolution and progenitors near…
Do accretion-powered stellar winds help spin down T Tauri stars?
Lukas Gehrig, Eric Gaidos, Laura Venuti +2
How T Tauri stars remain slowly rotating while still accreting material is a long-standing puzzle. Current models suggest that these stars may lose angular momentum through magneto…
Acoustic modes in M67 cluster stars trace deepening convective envelopes
Claudia Reyes, Dennis Stello, Joel Ong +3
Acoustic oscillations in stars are sensitive to stellar interiors. Frequency differences between overtone modes -- large separations -- probe stellar density, while differences bet…
