GD424 -- a helium-atmosphere white dwarf with a large amount of trace hydrogen in the process of digesting a rocky planetesimal
Paula Izquierdo, Odette Toloza, Boris T. Gänsicke +5
The photospheric metal pollution of white dwarfs is now well-established as the signature of the accretion of planetary debris. However, the origin of the trace hydrogen detected i…
Five New Post-Main-Sequence Debris Disks with Gaseous Emission
Erik Dennihy, Siyi Xu, Samuel Lai +13
Observations of debris disks, the products of the collisional evolution of rocky planetesimals, can be used to trace planetary activity across a wide range of stellar types. The mo…
Most EL CVn systems are inner binaries of hierarchical triples
F. Lagos, M. R. Schreiber, S. G. Parsons +2
In spite of their importance for modern astronomy, we do not fully understand how close binary stars containing at least one white dwarf form from main sequence binary stars. The d…
The white dwarf binary pathways survey V. The Gaia white dwarf plus AFGK binary sample and the identification of 23 close binaries
J. -J. Ren, R. Raddi, A. Rebassa-Mansergas +22
Close white dwarf binaries consisting of a white dwarf and an A, F, G or K type main sequence star, henceforth close WD+AFGK binaries, are ideal systems to understand the nature of…
Single magnetic white dwarfs with Balmer emission lines: A small class with consistent physical characteristics as possible signposts for close-in planetary companions
Boris T. Gaensicke, Pablo Rodriguez-Gil, Nicola P. Gentile Fusillo +4
We report the identification of SDSS J121929.45+471522.8 as the third apparently isolated magnetic (B~18.5+/-1.0,MG) white dwarf exhibiting Zeeman-split Balmer emission lines. The…
White dwarf pollution by hydrated planetary remnants: Hydrogen and Metals in WD J204713.76-125908.9
Matthew J. Hoskin, Odette Toloza, Boris T. Gänsicke +9
WD J204713.76-125908.9 is a new addition to the small class of white dwarfs with helium-dominated photospheres that exhibit strong Balmer absorption lines and atmospheric metal pol…
