Binaries discovered by the SPY project. III. HE 2209-1444: A massive, short period double degenerate
(2003-11)
In the course of our search for double degenerate (DD) binaries as potential progenitors of type Ia supernovae with the UVES spectrograph at the ESO VLT (ESO SN Ia Progenitor surveY – SPY) we discovered HE2209−1444 to be ...
2MASS J0516288+260738: Discovery of the first eclipsing late K + Brown dwarf binary system
(2003-11)
We report the discovery of a new eclipsing system less than one arcminute south of the pulsating DB white dwarf KUV05134+2605. The object could be identified with the point source 2MASSJ0516288+260738 published by the Two ...
SPY - the ESO Supernovae type Ia Progenitor survey
(2003)
Supernovae (SNe) mark the violent termination of a star’s life in an explosion. They are classified according to their light curve as type I or II, with the type I SNe producing very similar light curves, while the SNe ...
