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…
BVRI Light Curves for 29 Type Ia Supernovae
Mario Hamuy, M. M. Phillips, Nicholas B. Suntzeff +2
BVRI light curves are presented for 27 Type Ia supernovae discovered during the course of the Calan/Tololo Survey and for two other SNe Ia observed during the same period. Estimate…
