Now you see me, now you don't: Deep, long-lived obscuration events of white dwarfs by dust and debris from disintegrating planetesimals
J. van Roestel, S. Bhattacharjee, J. A. Guidry +22
Transiting dust and debris around white dwarfs provide a direct view of planetary disruption. We report six previously non-variable white dwarfs that underwent single, deep obscura…
The scarcity of white dwarf-brown dwarf binaries in the solar neighbourhood: A population synthesis study
Alejandro Santos-García, Santiago Torres, Alberto Rebassa-Mansergas +3
White dwarf--brown dwarf (WD--BD) binaries are intrinsically rare systems that provide a unique opportunity to study binary evolution and the formation of substellar companions. De…
Influence of mass-transfer stability on the formation of post-common-envelope binaries
Yanxu Shi, Hongwei Ge, Zhenwei Li +9
Post-common-envelope binaries are the natural laboratories for constraining the physics of common envelope evolution, which is one of the most uncertain phases in binary stellar ev…
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…
Extreme mass loss during common envelope evolution: the origin of the double low-mass white dwarf system J2102--4145
Leandro G. Althaus, Alejandro H. Corsico, Monica Zorotovic +3
Eclipsing close double white dwarf (WD) systems provide a unique opportunity to directly constrain hydrogen-envelope retention and test common-envelope (CE) evolution in low-mass s…
New axion bounds derived from the 100-parsec Gaia DR3 white dwarf luminosity function
Martín L. Alberino, Marcelo M. Miller Bertolami, María E. Camisassa +2
The axion, a well-motivated hypothetical particle arising in extensions of the Standard Model, can be produced copiously within the hot, compact cores of white dwarf stars. The sha…
