A Comprehensive Study of the Long-Period Cataclysmic Variable V630 Cassiopeiae
Ivan Mora Zamora, Gagik Tovmassian, Juan Echevarria +1
We present a comprehensive review of V630 Cassiopeiae, which is a very long-period cataclysmic variable. Based on new observations combining spectroscopy and high-resolution photom…
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…
Evolution of a long-period Cataclysmic Variable from the viewpoint of the donor star: the case of SDSS J085210.48+783246.6
G. Tovmassian, D. Belloni, I. Mora Zamora +8
Cataclysmic variables were long considered to be close binaries consisting of a white dwarf and a Roche-lobe-filling, near-zero-age main-sequence (ZAMS) red or brown dwarf. Recent…
No Period Change in Two Long-Period AM CVn Binaries
Matthew J. Green, Thomas R. Marsh, Jan van Roestel +25
Ultracompact binary systems, consisting of two compact objects in an orbit , should exhibit measurable rates of orbital period change () due t…
A modest change in magnetic braking at the fully convective boundary explains cataclysmic variable evolution
Joaquín A. Barraza-Jorquera, Matthias R. Schreiber, Stuart Littlefair +2
Context. For decades, reproducing the orbital period distribution of non-magnetic Cataclysmic Variables (CVs) seemed to require a drastic decrease, usually termed disruption, of an…
Distance Estimation and Sky Localization of Eccentric Double White Dwarf Binaries from Gravitational Wave Observations inside Globular Clusters
Yuetong Zhao, L. Hellström, Siqi Zhang +7
The cosmic distance scale is built on multiple different techniques for estimating distances in space that are often connected and dependent on multiple measurements and assumption…
From Main Sequence Binary to Blast: MESA Modeling of the Double-Detonation Progenitor PTF1~J2238+7430
Mercedes S. Hernandez, Thomas Kupfer, Diogo Belloni +1
Hot subdwarf B (sdB) stars in close binaries with white dwarf (WD) companions are potential progenitors of double-detonation thermonuclear supernovae. The recently discovered syste…
Predicted incidence of Jupiter-like planets around white dwarfs
Alex Mauch-Soriano, Matthias R. Schreiber, Diego Correa +7
Only a handful of gas giant planets orbiting white dwarfs are known. It remains unclear whether this paucity reflects observational challenges or the consequences of stellar evolut…
White Dwarf Binaries: Probes of Future Astrophysics
Anna F. Pala, Roberto Raddi, Alberto Rebassa-Mansergas +25
White dwarf binaries are fundamental astrophysical probes. They represent ideal laboratories to test the models of binary evolution, which also apply to the sources of gravitationa…
White Dwarfs in Wide Binary Systems as Reliable Age Calibrators
Alberto Rebassa-Mansergas, Roberto Raddi, Anna F. Pala +13
Deriving precise stellar ages is a challenging task. Consequently, age-dependent relations - such as the age-metallicity and age-velocity dispersion relations of the Milky Way, or…
The evolutionary history of ultra-compact accreting binaries. I. Chemical abundances and formation channel of the eclipsing AM CVn system ZTF J225237.05-051917.4 from HST spectroscopy
W. Yu, A. F. Pala, T. Kupfer +33
AM Canum Venaticorum (AM CVn) stars are ultra-compact binary systems composed of a white dwarf (WD) primary accreting from a H-deficient donor. They are important as potential prog…
