A 500 pc volume-limited sample of hot subluminous stars II. Atmospheric parameters, mass distribution, and kinematics
H. Dawson, M. Dorsch, S. Geier +30
We present a quantitative spectroscopic and kinematic analysis of a volume-complete sample of hot subluminous stars within 500 pc of the Sun, assembled using accurate parallax meas…
Searching for new variable white dwarfs: The discovery of the three new pulsating and three new binary systems
Larissa Antunes Amaral, Maja Vučković, Ingrid Pelisoli +3
In recent years, approximately 150 low-mass white dwarfs (WDs), typically with masses below 0.4 solar masses, have been discovered. Observational evidence indicates that most of th…
The impact of the uncertainties in the 12C(α,γ)16O reaction rate on the evolution of low- to intermediate-mass stars
Ben T. Pepper, A. G. Istrate, A. D. Romero +1
One of the largest uncertainties in stellar evolutionary computations is the accuracy of the considered reaction rates. The 12C(alpha,gamma)16O reaction is particularly important f…
Discovery of a highly magnetic He-sdO star from a double-degenerate binary merger
M. Dorsch, N. Reindl, I. Pelisoli +4
Helium-rich hot subdwarf stars of spectral type O (He-sdO) are considered prime candidates for stellar merger remnants. Such events should lead to the generation of strong magnetic…
Pulsating hydrogen-deficient white dwarfs and pre-white dwarfs observed with TESS II. Discovery of two new GW Vir stars: TIC333432673 and TIC095332541
Murat Uzundag, Alejandro H. Córsico, S. O. Kepler +8
In this paper, we present the observations of two new GW Vir stars from the extended \textit{TESS} mission in both 120\,s short-cadence and 20\,s ultra-short-cadence mode of two pr…
It has to be cool: on supergiant progenitors of binary black hole mergers from common-envelope evolution
J. Klencki, G. Nelemans, A. G. Istrate +1
Common-envelope (CE) evolution in massive binary systems is thought to be one of the most promising channels for the formation of compact binary mergers. In the case of merging bin…
