TESS Pulsation Timing Reveals the JWST Calibration Star HD 158485 as a Double-pulsator Binary
Chenglong Lv, Ali Esamdin, Shuguo Ma +5
HD~158485 is an A-type ~Scuti star in the CALSPEC network and the JWST absolute-flux calibration program. Gaia DR3 assigns it a binary classification probability close to unity…
TESS Observations of Seven Newly Identified High-amplitude Scuti Stars
Chenglong Lv, Ali Esamdin, Amir Hasanzadeh +3
We report seven newly identified high-amplitude Scuti (HADS) stars. Among them, two stars (TIC 30977864 and TIC 387379145) exhibit pure radial pulsation without the excitation…
Dynamical Mass Loss at the End of TP-AGB stars
Yingzhen Cui, Song Wang, Xiangcun Meng +3
The thermally pulsating asymptotic giant branch (TP-AGB) phase plays a key role in the evolution of low- to intermediate-mass stars, driving mass loss that influences their final s…
KIC 10417986: Spectroscopic confirmation of the nature of the binary system with a δ Scuti component
Guo-Jie Feng, Ali Esamdin, Jian-Ning Fu +9
KIC 10417986 is a short orbital period (0.0737 d) ellipsoidal variable star with a δ Scuti and γ Doradus hybrid pulsations component discovered by Kepler. The ground-based spectros…
