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 surveY – SPY). About 560 white dwarfs were checked for radial velocity variations until now. Ninety new DDs have been discovered, including short period systems with masses close to the Chandrasekhar mass. 1 The project Su...
متن کاملBinaries discovered by the SPY project III . HE 2209 − 1444 : A massive , short period double degenerate
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 HE 2209−1444 to be a double-lined system consisting of two DA white dwarfs. From the analysis of the radial velocity curve we determined the period of the system to be P = 6 h 38 m 47 s. The sem...
متن کاملNew Results from the Supernova Ia Progenitor Survey
We report on a systematic radial velocity survey for double degenerate (DD) binaries as potential progenitors of type Ia supernovae: SPY (ESO Supernovae Ia Progenitor surveY). More than 1000 white dwarfs and pre-white dwarfs were observed with the VLT. Our aim is to perform a statistically significant test of the DD scenario. SPY detected more than 100 new binary white dwarfs, dramatically incr...
متن کاملBinaries discovered by the SPY project II . HE 1414 – 0848 : A double degenerate with a mass close to the Chandrasekhar limit ?
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 that the white dwarf HE 1414−0848 is a double-lined DA+DA binary with an orbital period of P = 12 h 25 m 39 s. Semi-amplitudes of 128 km s −1 and 100 km s −1 are derived for the individual compo...
متن کاملBinary White Dwarfs in the Supernova Ia Progenitor Survey
We report results of a systematic radial velocity survey for double degenerate (DD) binaries as potential progenitors of type Ia supernovae: SPY (ESO Supernovae Ia Progenitor surveY). More than 1000 white dwarfs (WDs) and pre-white dwarfs were observed with the VLT. The aim of SPY is to perform a statistically significant test of the DD scenario. We give an overview of the project and follow-up...
