Wind-envelope interaction as the origin of the slow cyclic brightness variations of luminous blue variables
Luca Grassitelli, Norbert Langer, Jonathan Mackey +4
Luminous blue variables (LBVs) are hot, very luminous massive stars displaying large quasi-periodic variations in brightness, radius,and photospheric temperature, on timescales of…
The metallicity dependence of envelope inflation in massive stars
D. Sanyal, N. Langer, D. Szécsi +2
Recently it has been found that models of massive stars reach the Eddington limit in their interior, which leads to dilute extended envelopes. We perform a comparative study of the…
Asteroseismic test of rotational mixing in low-mass white dwarfs
A. G. Istrate, G. Fontaine, A. Gianninas +4
We exploit the recent discovery of pulsations in mixed-atmosphere (He/H), extremely low-mass white dwarf precursors (ELM proto-WDs) to test the proposition that rotational mixing i…
The IACOB project: III. New observational clues to understand macroturbulent broadening in massive O- and B-type stars
S. Simón-Díaz, M. Godart, N. Castro +5
We aim to provide new empirical clues about macroturbulent spectral line broadening in O- and B-type stars to evaluate its physical origin. We use high-resolution spectra of ~430 s…
