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…
Timing variations in the secondary eclipse of NN Ser
S. G. Parsons, T. R. Marsh, M. C. P. Bours +6
The eclipsing white dwarf plus main-sequence binary NN Serpentis provides one of the most convincing cases for the existence of circumbinary planets around evolved binaries. The ex…
The planets around NN Ser: still there
T. R. Marsh, S. G. Parsons, M. C. P. Bours +6
We present 25 new eclipse times of the white dwarf binary NN Ser taken with the high-speed camera ULTRACAM on the WHT and NTT, the RISE camera on the Liverpool Telescope, and HAWK-…
A magnetic white dwarf in a detached eclipsing binary
S. G. Parsons, T. R. Marsh, B. T. Gänsicke +4
SDSS J030308.35+005444.1 is a close, detached, eclipsing white dwarf plus M dwarf binary which shows a large infrared excess which has been interpreted in terms of a circumbinary d…
Single degenerate supernova type Ia progenitors
M. C. P. Bours, S. Toonen, G. Nelemans
There is general agreement that supernovae Ia correspond to the thermonuclear runaway of a white dwarf that is part of a compact binary, but the details of the progenitor systems a…
Binary population synthesis and SNIa rates
S. Toonen, G. Nelemans, M. Bours +1
Despite the significance of type Ia supernovae (SNeIa) in many fields in astrophysics, SNeIa lack a theoretical explanation. We investigate the potential contribution to the SNeIa…
