Type II supernova spectral diversity I: Observations, sample characterization and spectral line evolution
Claudia P. Gutiérrez, Joseph P. Anderson, Mario Hamuy +23
We present 888 visual-wavelength spectra of 122 nearby type II supernovae (SNe II) obtained between 1986 and 2009, and ranging between 3 and 363 days post explosion. In this first…
Distance to NGC 0247
Barry F. Madore, Wendy L. Freedman, J. Catanzarite +1
We report VRI CCD observations of nine Cepheids in the South Polar (Sculptor) Group spiral galaxy NGC 0247. Periods of these Cepheids range from 20 to 70 days. Over the past 20 yea…
The Luminous Type Ic SN 1992ar at z=0.145
Alejandro Clocchiatti, Mark M. Phillips, Nicholas B. Suntzeff +13
We present spectroscopic and photometric observations of SN1992ar, the more distant SN in the Calan/Tololo Survey. We compare its spectrum with those of nearby Type Ia and Ic SNe a…
Optical Light Curve of the Type Ia Supernova 1998bu in M96 and the Supernova Calibration of the Hubble Constant
Nicholas B. Suntzeff, M. M. Phillips, R. Covarrubias +15
We present the UBVRI light curves of the Type Ia supernova SN 1998bu which appeared in the nearby galaxy M96 (NGC 3368). M96 is a spiral galaxy in the Leo I group which has a Cephe…
BVRI Light Curves for 22 Type Ia Supernovae
Adam G. Riess, Robert P. Kirshner, Brian P. Schmidt +6
We present 1210 Johnson/Cousins B,V,R, and I photometric observations of 22 recent type Ia supernovae (SNe Ia): SN 1993ac, SN 1993ae, SN 1994M, SN 1994S, SN 1994T, SN 1994Q, SN 199…
Optical Light Curves of the Type Ia Supernovae 1990N and 1991T
P. Lira, Nicholas B. Suntzeff, M. M. Phillips +27
We present UBVRI light curves for the bright Type Ia supernovae SN 1990N in NGC 4639 and SN 1991T in NGC 4527 based on photometry gathered in the course of the Calan/Tololo superno…
