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…
Observing bright pulsating white dwarfs with PLATO: A new window into the late stages of stellar evolution
Murat Uzundag, Alejandro H. Corsico, Nicholas Jannsen +17
We present the scientific case for exploiting the capabilities of the PLATO mission to study bright pulsating white dwarfs across a wide spectral range, including hydrogen-deficien…
Circumstellar interaction in the extreme white dwarf merger remnant ZTF\,J1901+1458: A new class of white dwarf merger remnants with X-ray emission
Aayush Desai, Ilaria Caiazzo, Stephane Vennes +31
Double degenerate white dwarf (WD) mergers can exhibit extreme magnetic fields exceeding G and rapid rotation, but their spectral-energy distributions and high-energy emis…
Evolution of a Long-Lived Deep-Seated Main-Sequence Magnetic Field During White Dwarf Cooling
Matias Castro-Tapia, Maria Camisassa, Shu Zhang
We study the evolution of white dwarf (WD) magnetic fields that originate from core-convective dynamos during the main-sequence. Using stellar evolution and WD cooling models combi…
Magnetic White Dwarfs in the SDSS 100 pc Sample: Further Evidence of Two Formation Channels
Adam Moss, Mukremin Kilic, Pierre Bergeron +5
We conduct a model atmosphere analysis on all magnetic white dwarfs in the SDSS 100 pc sample. We have 163 magnetic targets in this sample, 87 of which are new discoveries, making…
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…
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…
