Query: Hunting for the progenitor of SN 1006: High resolution spectroscopic
  search with the FLAMES instrument   Type Ia supernovae play a significant role in the evolution of the Universe
and have a wide range of applications. It is widely believed that these events
are the thermonuclear explosions of carbon-oxygen white dwarfs close to the
Chandrasekhar mass (1.38 M\odot). However, CO white dwarfs are born with masses
much below the Chandrasekhar limit and thus require mass accretion to become
Type Ia supernovae. There are two main scenarios for accretion. First, the
merger of two white dwarfs and, second, a stable mass accretion from a
companion star. According to predictions, this companion star (also referred to
as donor star) survives the explosion and thus should be visible in the center
of Type Ia remnants. In this paper we scrutinize the central stars (79 in
total) of the SN 1006 remnant to search for the surviving donor star as
predicted by this scenario. We find no star consistent with the traditional
accretion scenario in SN1006.
