Supernova 2008ha in UGC 12682.

FOLEY R.J.

Abstract (from CDS):

The spectrum does not have a red continuum, and there is no strong Na D absorption in the spectrum, indicating that 2008ha is not heavily reddened. Assuming (a) a distance modulus of 31.2 ± 0.5 mag – derived from a redshift of 1393 km/s from Yu et al. (1993, Ap.J. Suppl. 88, 383), and allowing for several flow models; (b) small Milky Way and host-galaxy extinction; and (c) that the unfiltered magnitudes reported on CBET 1567 approximate those of the R band, SN 2008ha had an absolute red magnitude of M_R = -13 ± 1 at peak. SNe 2002cx and 2005hk had M_R = -17.6 and -18.3 mag, respectively. Considering the extremely low absolute magnitude and low ejecta velocity, which imply a very low total energy release, Foley et al. wonder if 2008ha is a true supernova that destroyed the progenitor star; if it is, then 2008ha is possibly the least luminous supernova ever observed.
