The theoretical pulsation spectra of hot B subdwarfs. Static and evolutionary STELUM models
N. Guyot, V. Van Grootel, S. Charpinet +3
Context. The Kepler and TESS space missions have revealed the rich gravity (g-)mode pulsation spectra of many hot subdwarf B (sdB) stars in detail. These spectra exhibit complex be…
Detailed seismic study of Gemma (KIC11026764) using EGGMiMoSA: Unveiling the probing potential of mixed modes for subgiant stars
M. Farnir, M. -A. Dupret, G. Buldgen
Context. When leaving the main sequence (MS) for the red-giant branch (RGB), subgiant stars undergo fast structural changes. Consequently, their observed oscillation spectra mirror…
Is planetary inward migration responsible for GJ 504's fast rotation and bright X-ray luminosity? New constraints from eROSITA
C. Pezzotti, G. Buldgen, E. Magaudda +4
The discovery of an increasing variety of exoplanets in very close orbits around their host stars raised many questions about how stars and planets interact, and to which extent ho…
MCMC inversions of the internal rotation of Kepler subgiants
G. Buldgen, L. Fellay, J. Bétrisey +3
The measurement of the internal rotation of post-main sequence stars using data from space-based photometry missions has demonstrated the need for an efficient angular momentum tra…
