  I suggest that in rare cases type Ia supernovae (SNe Ia) evaporate
Jupiter-like planets that reside within a=50Ro from the SN, accounting for the
presence of ~0.001Mo of hydrogen in the ejecta. It is not easy to form such
planets. The common envelope evolution (CEE) might end with the formation of a
circumbinary disk with a typical size of R(disk)~10-50Ro. However, the bright
central star might prevent the formation of planets. Alternatively, the planets
might be first-generation planets that survived the entire evolution.
Interestingly, all five SN Ia binary scenarios (core degenerate; double
degenerate; double detonation; single degenerate; WD-WD collision) might
account for the presence of planets.
