EXPANDING MOLECULAR BUBBLE SURROUNDING TYCHO'S SUPERNOVA REMNANT (SN 1572) OBSERVED WITH THE IRAM 30 m TELESCOPE: EVIDENCE FOR A SINGLE-DEGENERATE PROGENITOR

ABSTRACT Whether the progenitors of SNe Ia are single-degenerate or double-degenerate white dwarf (WD) systems is a highly debated topic. To address the origin of Tycho's Type Ia supernova remnant (SNR), SN 1572, we have carried out a 12CO J = 2-1 mapping and a 3 mm line survey toward the remna...
