Any colour you like: The diverse chromaticities of white dwarfs

Mark A. Hollands, Boris T. Gaensicke, Pier-Emmanuel Tremblay +1

Main sequence stars have perceived colours ranging from orange to white to blue with increasing effective temperature. This is because their atmospheric opacities cause only minor…

A Spectroscopic Census of Cluster White Dwarfs from DESI, LAMOST, and SDSS

David R. Miller, Jeremy Heyl, Huahui Yan +2

Gaia has substantially expanded the sample of candidate white dwarfs (WDs) in open clusters, but many remain without spectroscopic characterization. We leverage the increasingly ex…

Atypical White Dwarfs in Open Clusters

David R. Miller, Ilaria Caiazzo, Jeremy Heyl +1

Open clusters are powerful laboratories for investigating the formation and evolution of white dwarfs (WDs), as their well-constrained ages link WDs to their progenitor stars. This…

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.…
