The Type la Supernova 2001V in NGC 3987

Abstract

CCD photometry of the type Ia SN 2001V occured in the edge-on spiral galaxy NGC 3987 is presented. The observations made through Johnson-Cousins BVRI filters were collected from Feb. 24 (t = -8 days, with respect to B-maximum), up to May 5 (t = +62 days). The light curves are analyzed with the revised Multi-Colour Light Curve Shape (MLCS) method by fitting template vectors to the observed light curves simultaneously. The reddening of SN 2001V is estimated to be E(B-V)=0.05 mag, while the galactic component is E(B-V) = 0.02 mag, suggesting that part of the reddening may be due to the ISM in the host galaxy. The Delta parameter in MLCS converged to -0.47 mag, indicating that this SN was overluminous relative to the majority of Type Ia SNe. The inferred distance to its host galaxy, NGC 3987, is 74.5 \pm 5 Mpc, which is in good agreement with recently determined kinematic distances, based on radial velocity corrected for Virgo-infall and Hubble constant H_0 = 65 km/s/Mpc.
