Calibrating Eruptive Mass Loss in Red Supergiants with Local Group Data
The Astrophysical JournalWe calibrate a physically motivated, super-Eddington eruptive mass-loss prescription for red supergiants (RSGs) using Local Group stellar populations.

The Astrophysical Journal LettersMass loss in low-mass stars during the red giant branch (RGB) and early asymptotic giant branch (EAGB) phases plays a key role in shaping stellar evolution, yet its dependence on stellar parameters such as metallicity remains poorly constrained, with ...

Mass Loss in 2D ZAMS Stellar Models
, 2011 A large number of massive stars are known to rotate, resulting in significant distortion and variation in surface temperature from the pole to the equator. Radiatively driven mass loss is temperature dependent, so rapid rotation produces variation in mass loss and angular momentum loss rates across the surface of the star, which is expected to affect ...

Can the Anomalous Magnetic Braking of Ap/Bp Stars Explain the Orbital Decay of Algol-type Binaries?
The Astrophysical JournalSeveral Algol-type binaries were detected to be experiencing rapid orbital decay, which is in contradiction with the conservative mass transfer model. In this work, we investigate whether anomalous magnetic braking (MB) of intermediate-mass Ap/Bp stars ...

The Astrophysical JournalRed giants experience significant mass loss, but the mechanism is poorly understood. The surface [C/N] of red giants is correlated with birth mass but not directly impacted by mass loss. Exploiting this, we compare asteroseismic masses of red giants with

Observations and Radiative Transfer Simulations of the Carbon-rich AGB Star V Oph with VLTI/MATISSE
The Astrophysical JournalCarbon-rich asymptotic giant branch (AGB) stars are among the most important contributors of enriched materials to the interstellar medium due to their strong stellar winds.

Li Enrichment in Red Clump Giants: Clues for Past Binary Interaction or Merger Events
The Astrophysical Journal LettersTo understand the underlying mechanisms of high Li abundances among core He-burning or red clump (RC) giants, we analyzed a sample of 5227 RC giants of mass M ≤ 2 M _⊙ using spectra and asteroseismic data.

JWST/MIRI Detection of [Ne v], [Ne vi], and [O iv] Wind Emission in the O9 V Star 10 Lacertae
The Astrophysical Journal LettersWe report the detection of broad, flat-topped emission in the fine-structure lines of [Ne v ], [Ne vi ], and [O iv ] in mid-infrared spectra of the O9 V star 10 Lacertae obtained with James Webb Space Telescope/Mid-Infrared Instrument.
