A 500 pc volume-limited sample of hot subluminous stars III. The short-period binary population
H. Dawson, M. Dorsch, J. Munday +16
Hot subdwarf stars of spectral types O and B (sdO/B) in binaries form as products of substantial mass loss near the tip of the red giant branch and offer powerful constraints on bi…
An Ultramassive White Dwarf with a Likely Oxygen-Neon Core
Stefan M. Arseneau, J. J. Hermes, Vedant Chandra +4
The core composition of ultramassive white dwarfs remains an open question in stellar evolution. The carbon content of white dwarf cores is critical to their role as progenitors of…
Revisiting the Galactic age-metallicity relation from wide white dwarf-main-sequence binaries
Alberto Rebassa-Mansergas, Iset Tejero-Gómez, Roberto Raddi
The age-metallicity relation (AMR) is a fundamental observational constraint for understanding the chemical evolution of the Galaxy. As reliable cosmochronometers, white dwarfs in…
Constraints on White Dwarf Hydrogen Layer Masses Using Gravitational Redshifts
Stefan M. Arseneau, J. J. Hermes, Maria E. Camisassa +2
The hydrogen envelope is the outermost layer of a DA white dwarf; it makes up the entirety of the stellar photosphere, and yet its typical extent is difficult to model theoreticall…
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…
Asteroseismology of white dwarfs in the 2040s
Murat Uzundag, Ingrid Pelisoli, Stephane Charpinet +6
White dwarfs, the final evolutionary stage of the vast majority of stars, serve as critical tools for cosmochronology, studies of planetary system evolution, and laboratories for n…
The Future of Evolved Planetary Systems
Roberto Raddi, Anna F. Pala, Alberto Rebassa-Mansergas +19
Understanding the formation, evolution, and chemical diversity of exoplanets are now central areas of astrophysics research. White dwarfs provide a uniquely sensitive laboratory fo…
Structure and evolution of ultra-massive white dwarfs in general relativity
L. G. Althaus, M. E. Camisassa, S. Torres +4
We present the first set of constant rest-mass ultra-massive oxygen/neon white dwarf cooling tracks with masses larger than 1.29 Msun which fully take into account the effects of g…
The White Dwarf Binary Pathways Survey IV: Three close white dwarf binaries with G-type secondary stars
M. S. Hernandez, M. R. Schreiber, S. G. Parsons +12
Constraints from surveys of post common envelope binaries (PCEBs) consisting of a white dwarf plus an M-dwarf companion have led to significant progress in our understanding of the…
Mode identification in three pulsating hot subdwarfs observed with TESS satellite
S. K. Sahoo, A. S. Baran, U. Heber +12
We report on the detection of pulsations of three pulsating subdwarf B stars observed by the TESS satellite and our results of mode identification in these stars based on an asympt…
Crossing the Gould Belt in the Orion vicinity
K. Biazzo, J. M. Alcalá, E. Covino +5
We present a study of the large-scale spatial distribution of 6482 RASS X-ray sources in approximately 5000 deg^2 in the direction of Orion. We examine the astrophysical properties…
