Symbiotic Stars (Including T Corona Borealis) Are Not Immediate Progenitors of Normal Type Ia Supernovae

The Astrophysical Journal
A popular solution to the Type Ia supernova (SN Ia) progenitor problem is that the immediate progenitors are symbiotic star systems. This solution requires that the companion star of the exploding white dwarf must be a red giant star with a heavy stellar

H I 21 cm Absorption Associated with Foreground Galaxies on Top of Quasars

The Astrophysical Journal
A systematic search for H i 21 cm absorption in quasar–galaxy pairs (QGPs) provides a powerful means to map the distribution of cold gas around high-redshift star-forming galaxies.

CO Isotopologue-derived Molecular Gas Conditions and CO-to-H2 Conversion Factors in M51

The Astronomical Journal
Over the past decade, several millimeter interferometer programs have mapped the nearby star-forming galaxy M51 at a spatial resolution of ≤170 pc. This study combines observations from three major programs: the PdBI Arcsecond Whirlpool Survey, the SMA ...
