Perfecting our set of spectrophotometric standard DA white dwarfs
A. Calamida, T. Matheson, E. W. Olszewski +17
We verified for photometric stability a set of DA white dwarfs with Hubble Space Telescope magnitudes from the near-ultraviolet to the near-infrared and ground-based spectroscopy b…
Alkali metals in white dwarf atmospheres as tracers of ancient planetary crusts
Mark A. Hollands, Pier-Emmanuel Tremblay, Boris T. Gänsicke +2
White dwarfs that accrete the debris of tidally disrupted asteroids provide the opportunity to measure the bulk composition of the building blocks, or fragments, of exoplanets. Thi…
An ultra-massive white dwarf with a mixed hydrogen-carbon atmosphere as a likely merger remnant
Mark A. Hollands, Pier-Emmanuel Tremblay, Boris T. Gänsicke +11
White dwarfs are dense, cooling stellar embers consisting mostly of carbon and oxygen, or oxygen and neon (with a few percent carbon) at higher initial stellar masses. These stella…
IGAPS: the merged IPHAS and UVEX optical surveys of theNorthern Galactic Plane
M. Monguió, R. Greimel, J. E. Drew +47
The INT Galactic Plane Survey (IGAPS) is the merger of the optical photometric surveys, IPHAS and UVEX, based on data from the Isaac Newton Telescope (INT) obtained between 2003 an…
The Gaia 20 pc white dwarf sample
M. A. Hollands, P. E. Tremblay, B. T. Gaensicke +2
Using Gaia DR2 data, we present an up-to-date sample of white dwarfs within 20 pc of the Sun. In total we identified 139 systems in Gaia DR2, nine of which are new detections, with…
Further insight on the hypervelocity white dwarf, LP 40-365 (GD 492): a nearby emissary from a single-degenerate Type Ia supernova
R. Raddi, M. A. Hollands, D. Koester +4
The recently discovered hypervelocity white dwarf LP 40-65 (aka GD 492) has been suggested as the outcome of the failed disruption of a white dwarf in a sub-luminous Type Ia supern…
