Properties of the Eclipsing Double-White Dwarf Binary NLTT 11748
David L. Kaplan, Thomas R. Marsh, Arielle N. Walker +9
We present high-quality ULTRACAM photometry of the eclipsing detached double-white dwarf binary NLTT 11748. This system consists of a carbon/oxygen white dwarf and an extremely-low…
Orbital Evolution of Compact White Dwarf Binaries
David L. Kaplan, Lars Bildsten, Justin D. R. Steinfadt
The new-found prevalence of extremely low mass (ELM, Mhe<0.2 Msun) helium white dwarfs (WDs) in tight binaries with more massive WDs has raised our interest in understanding the na…
A Search for Pulsations in Helium White Dwarfs
Justin D. R. Steinfadt, Lars Bildsten, David L. Kaplan +5
The recent plethora of sky surveys, especially the Sloan Digital Sky Survey, have discovered many low-mass (M < 0.45 Msun) white dwarfs that should have cores made of nearly pure h…
A ground-based measurement of the relativistic beaming effect in a detached double WD binary
Avi Shporer, David L. Kaplan, Justin D. R. Steinfadt +3
We report on the first ground-based measurement of the relativistic beaming effect (aka Doppler boosting). We observed the beaming effect in the detached, non-interacting eclipsing…
Discovery of the Eclipsing Detached Double White Dwarf Binary NLTT 11748
Justin D. R. Steinfadt, David L. Kaplan, Avi Shporer +2
We report the discovery of the first eclipsing detached double white dwarf (WD) binary. In a pulsation search, the low-mass helium core WD NLTT 11748 was targeted for fast (approx…
Pulsations in Hydrogen Burning Low Mass Helium White Dwarfs
Justin D. R. Steinfadt, Lars Bildsten, Phil Arras
Helium core white dwarfs (WDs) with mass M <~ 0.20 Msun undergo several Gyrs of stable hydrogen burning as they evolve. We show that in a certain range of WD and hydrogen envelope…
