The timescale of low-mass proto-helium white dwarf evolution
Alina Istrate, Thomas Tauris, Norbert Langer +1
A large number of low-mass (< 0.20 M_sun) helium white dwarfs (He WDs) have recently been discovered. The majority of these are orbiting another WD or a millisecond pulsar (MSP) in…
Stellar archaeology with Gaia: the Galactic white dwarf population
Boris Gaensicke, Pier-Emmanuel Tremblay, Martin Barstow +23
Gaia will identify several 1e5 white dwarfs, most of which will be in the solar neighborhood at distances of a few hundred parsecs. Ground-based optical follow-up spectroscopy of t…
Astrophysics with the Laser Interferometer Space Antenna
Pau Amaro Seoane, Jeff Andrews, Manuel Arca Sedda +156
The Laser Interferometer Space Antenna (LISA) will be a transformative experiment for gravitational wave astronomy, and, as such, it will offer unique opportunities to address many…
Models of low-mass helium white dwarfs including gravitational settling, thermal and chemical diffusion, and rotational mixing
Alina Istrate, Pablo Marchant, Thomas M. Tauris +3
A large number of extremely low-mass helium white dwarfs (ELM WDs) have been discovered in recent years. The majority of them are found in close binary systems suggesting they are…
Stellar response after stripping as a model for common-envelope outcomes
Alejandro Vigna-Gómez, Michelle Wassink, Jakub Klencki +3
Binary neutron stars have been observed as millisecond pulsars, gravitational-wave sources, and as the progenitors of short gamma-ray bursts and kilonovae. Massive stellar binaries…
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…
