Kilogauss magnetic fields from simulations of small-scale dynamo action in the convective envelope of a white dwarf
Fabio Riva, Tim Cunningham, Hans-Günter Ludwig +2
About 20% of white dwarfs are observed to host large-scale magnetic fields, but the origin of white dwarf magnetism remains uncertain. Small-scale turbulent dynamos (SSDs), which e…
Investigating the Observational Progenitor Mass Gap in the White Dwarf Initial-Final Mass Relation. I. Cluster Census and Characterization of the First White Dwarfs in the Gap
David R. Miller, Jeremy Heyl, Pier-Emmanuel Tremblay
In recent years, Gaia has been the primary driver of the expansion of the white dwarf (WD) initial-final mass relation (IFMR) in open clusters. The increased sample size has highli…
A Framework for Linking Pre- and Post-Common Envelope Binary Properties with Star Clusters: The First Demonstration with a Massive White Dwarf+M Dwarf Binary in Alessi 12
Steffani M. Grondin, Maria R. Drout, Jason Nordhaus +12
Common envelope (CE) evolution is a critical phase in the lives of binary stars, producing close binaries that are progenitors of type Ia supernovae and gravitational wave sources.…
Direct detections of white dwarfs in four WD+dM post-common envelope binaries within 20 pc
Mairi W. O'Brien, David J. Wilson, Pier-Emmanuel Tremblay +5
The paper reports the first direct spectroscopic detections of white dwarf companions in four nearby post‑common envelope binaries, using HST near‑UV observations to determine thei…
Physics of Eclipsing Binaries. VI. Hot, compact stars
David Jones, Nicole Reindl, Kyle Conroy +9
Models of eclipsing binaries require the assignment of appropriate emergent intensities to the surface elements of the binary components. For distance-dependent modelling of flux-c…
White dwarfs within 13 pc: Insights from ultraviolet spectroscopy
Mairi W. O'Brien, Pier-Emmanuel Tremblay, Boris T. Gaensicke +9
We present a comprehensive multi-wavelength spectroscopic and photometric analysis of the 44 confirmed white dwarfs within 13 pc of the Sun. Combining flux-calibrated ultraviolet (…
