Two new ZZ Ceti pulsators from the HS and HE surveys
R. Silvotti, B. Voss, I. Bruni +4
We report the detection of nonradial g-mode oscillations in the DA white dwarfs HS1039+4112 (B=15.9) and HE1429-0343 (B=15.8) from time-series photometry made at the Loiano 1.5 m t…
Double degenerates and progenitors of supernovae type Ia
R. Napiwotzki, L. Yungelson, G. Nelemans +12
We report on systematic radial velocity surveys for white dwarf - white dwarf binaries (double degenerates - DDs) including SPY (ESO Supernovae Ia progenitor survey) recently carri…
Search for double degenerate progenitors of supernovae type Ia with SPY
R. Napiwotzki, H. Drechsel, U. Heber +13
We report on a large survey for double degenerate (DD) binaries as potential progenitors of type Ia supernovae with the UVES spectrograph at the ESO VLT (ESO SN Ia Progenitor surve…
Four magnetic DB white dwarfs discovered by the Hamburg/ESO survey
D. Reimers, S. Jordan, V. Beckmann +2
We report on seven peculiar faint blue stars found in the course of the Hamburg/ESO survey (HES) which appear to be magnetic white dwarfs (WDs) with non-hydrogen spectra. We show i…
