Is SN 2006X from a WD + MS system with optically thick wind?
The single-degenerate channel is widely accepted as the progenitors of type
Ia supernovae (SNe Ia). Following the work of Meng, Chen and Han (2009), we
reproduced the birth rate and age of supernovae like SN 2006X by the
single-degenerate model (WD + MS) with an optically thick wind, which may imply
that the progenitor of SN 2006X is a WD + MS system.Comment: 10 pages, 2 figures, accepted for publication in New
WD + MS systems as the progenitor of SNe Ia
We show the initial and final parameter space for SNe Ia in a () plane and find that the positions of some famous
recurrent novae, as well as a supersoft X-ray source (SSS), RX J0513.9-6951,
are well explained by our model. The model can also explain the space velocity
and mass of Tycho G, which is now suggested to be the companion star of Tycho's
supernova. Our study indicates that the SSS, V Sge, might be the potential
progenitor of supernovae like SN 2002ic if the delayed dynamical-instability
model due to Han & Podsiadlowski (2006) is appropriate. Following the work of
Meng, Chen & Han (2009), we found that the SD model (WD + MS) with an optically
thick wind can explain the birth rate of supernovae like SN 2006X and reproduce
the distribution of the color excess of SNe Ia. The model also predicts that at
least 75% of all SNe Ia may show a polarization signal in their spectra.Comment: 6 pages, 2 figures, accepted for publication in Astrophysics & Space
