From Hydrogen to Helium: The Spectral Evolution of White Dwarfs as Evidence for Convective Mixing
Tim Cunningham, Pier-Emmanuel Tremblay, Nicola Pietro Gentile Fusillo +2
We present a study of the hypothesis that white dwarfs undergo a spectral change from hydrogen- to helium-dominated atmospheres using a volume-limited photometric sample drawn from…
Interpretation and diversity of exoplanetary material orbiting white dwarfs
Andrew Swan, Jay Farihi, Detlev Koester +5
Nine metal-polluted white dwarfs are observed with medium-resolution optical spectroscopy,where photospheric abundances are determined and interpreted through comparison against so…
Core crystallization and pile-up in the cooling sequence of evolving white dwarfs
Pier-Emmanuel Tremblay, Gilles Fontaine, Nicola Pietro Gentile Fusillo +7
White dwarfs are stellar embers depleted of nuclear energy sources that cool over billions of years. These stars, which are supported by electron degeneracy pressure, reach densiti…
A Volume Limited Sample of Cataclysmic Variables from DR2: Space Density and Population Properties
A. F. Pala, B. T. Gänsicke, E. Breedt +15
We present the first volume-limited sample of cataclysmic variables (CVs), selected using the accurate parallaxes provided by the second data release (DR2) of the ESA $\mathit{Gaia…
Astro 2020 Science White Paper: Evolved Planetary Systems around White Dwarfs
Boris Gaensicke, Martin Barstow, Amy Bonsor +25
Practically all known planet hosts will evolve into white dwarfs, and large parts of their planetary systems will survive this transition - the same is true for the solar system be…
A planetesimal orbiting within the debris disc around a white dwarf star
Christopher J. Manser, Boris T. Gänsicke, Siegfried Eggl +29
Many white dwarf stars show signs of having accreted smaller bodies, implying that they may host planetary systems. A small number of these systems contain gaseous debris discs, vi…
Partly burnt runaway stellar remnants from peculiar thermonuclear supernovae
R. Raddi, M. A. Hollands, D. Koester +13
We report the discovery of three stars that, along with the prototype LP40-365, form a distinct class of chemically peculiar runaway stars that are the survivors of thermonuclear e…
