We report on the current status of radial velocity surveys for white dwarf binaries (double degenerates DDs) including SPY (ESO Supernovae la progenitor survey) recently carried out at the VLT. A large sample of DD will allow us to put strong constraints on the phases of close binary evolution of the progenitor systems and to perform an observational test of the DD scenario for Supernovae of type Ia.

Resumen

Resumen

Informamos sobre el estado actual de los “surveys” de velocidades radiales para binarias de euanas blancas (degeneradas dobles - DDs) incluyendo SPY (Exploración ESO de progenitoras de supernovas Ia) que reeientemente se llevaron a cabo en el VLT. Una amplia muestra de DDs nos permitirá poner fuertes restricciones sobre las fases evolutivas de los sistemas progenitores de binarias cereanas y también llevar a cabo pruebas observacionales del escenario DD para supernovas de tipo Ia.
