A Model of the Local WD Population
(Astronomical Society of the Pacific, 2005)
We present a model of the solar neighbourhood (d<100 pc) white dwarf (WD) population and show its distribution in e®ective temperature and mass. The WDs are created by the death-rate of a population model matching the local ...
Subdwarf B Binaries from the SPY Project
(Astronomical Society of the Pacific, 2005)
In the course of our search for double degenerate binaries as potential progenitors of type Ia supernovae with the ESO VLT (ESO - SN Ia progenitor survey - SPY), several sdB binaries were discovered. We report on the ...
