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…
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…
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 Galactic White Dwarf Population
Santiago Torres, Roberto Raddi, Alberto Rebassa-Mansergas +15
The ESA Gaia mission has revolutionized our understanding of the white dwarf population, delivering an unprecedented census of these nearby remnants and revealing previously unseen…
Multiperiodic pulsations of the unique DAQ white dwarf J0551+4135: insights into a merger remnant
Murat Uzundag, Mukremin Kilic, Francisco C. De Gerónimo +7
2MASS J05513444+4135297 (herafter J0551+4135) is the only pulsating DAQ white dwarf known with a carbon and hydrogen atmosphere. Its unusual atmospheric composition and kinematics…
The ZZ Ceti Instability Strip for The Most Massive White Dwarf Pulsators
Gracyn Jewett, Mukremin Kilic, Adam Moss +10
We present time-series photometry of 31 massive DA white dwarfs with within the ZZ Ceti instability strip from the Montreal White Dwarf Database 100 pc sampl…
J-PLUS: Understanding outlier white dwarfs in the third data release via dimensionality reduction
C. López-Sanjuan, P. -E. Tremblay, A. del Pino +20
We present the white dwarf catalog derived from the third data release of the Javalambre Photometric Local Universe Survey (J-PLUS DR3), which covers 3284 deg2 using 12 optical fil…
Spectroscopic and kinematic analyses of a warm survivor of a D6 supernova
Mark A. Hollands, Ken. J. Shen, Roberto Raddi +3
SDSSJ163712.21+363155.9 is a candidate hyper-runaway star, first identified from its unusual spectrum in the Sloan Digital Sky Survey, which exhibits oxygen, magnesium, and silicon…
Asteroseismology of WD J004917.14-252556.81, the Most Massive Pulsating White Dwarf
O. Caliskan, M. Uzundag, M. Kilic +10
We present extensive follow-up time-series photometry of WD J00492525, the most massive pulsating white dwarf currently known with and $\log{\i…
A magnitude-limited catalogue of unresolved white dwarf-main sequence binaries from Gaia DR3
Alberto Rebassa-Mansergas, Enrique Solano, Alex J. Brown +6
Binary stars containing a white dwarf and a main-sequence star, WDMS binaries, can be used to study a wide range of aspects of stellar astrophysics. We build a magnitude-limited sa…
Reconstructing post-common envelope white dwarf+main sequence binary histories through inverse population synthesis techniques
Santiago Torres, Marta Gili, Alberto Rebassa-Mansergas +3
The evolution of binary stellar systems involves a wide range of physical processes, many of which are not yet well understood. We aim to build a general-purpose algorithm based on…
A population synthesis study of the Gaia 100 pc unresolved white dwarf-main sequence binary population
Alejandro Santos-García, Santiago Torres, Alberto Rebassa-Mansergas +1
Binary stars consisting of a white dwarf and a main sequence star (WDMS) are valuable for studying key astrophysical questions. However, observational biases strongly affect the kn…
Testing the mass-radius relation of white dwarfs in common proper motion pairs I.Hydrogen-dominated atmospheres
Roberto Raddi, Alberto Rebassa-Mansergas, Santiago Torres +6
The main goal of this work was to measure the masses and radii of white dwarfs that belong to widely separated, common proper motion binaries with non-degenerate companions. These…
Two almost planetary mass survivors of common envelope evolution
S. G. Parsons, A. J. Brown, S. L. Casewell +19
White dwarfs are often found in close binaries with stellar or even substellar companions. It is generally thought that these compact binaries form via common envelope evolution, t…
Discovery of the richest pulsating ultra-massive white dwarf
Francisco C. De Geronimo, Murat Uzundag, Alberto Rebassa-Mansergas +5
The discovery of pulsations in ultra-massive white dwarfs can help to probe their interiors and unveil their core composition and crystallized mass fraction through asteroseismic t…
