Photometry of the Type Ia Supernovae 1999cc, 1999cl, and 2000cf Academic Article uri icon

abstract

  • We present previously unpublished BVRI photometry of the Type Ia supernovae 1999cc and 2000cf along with revised photometry of SN 1999cl. We confirm that SN 1999cl is reddened by highly nonstandard dust, with R v = 1.55 ± 0.08. Excepting two quasar-lensing galaxies whose low values of R v are controversial, this is the only known object with a published value of R v less than 2.0. SNe 1999cl and 2000cf have near-infrared absolute magnitudes at maximum in good agreement with other Type Ia supernovae of midrange decline rates. © 2006. The American Astronomical Society.
