The rate of Supernovae from the combined sample of five searches
E. Cappellaro, M. Turatto, D. Yu. Tsvetkov +4
With the purpose to obtain new estimates of the rate of supernovae we joined the logs of five SN searches, namely the Asiago, Crimea, Cal{á}n-Tololo and OCA photographic surveys an…
Maximum Brightness and Post-Maximum Decline of Light Curves of SN~Ia: A Comparison of Theory and Observations
P. Höflich, A. Khokhlov, J. C. Wheeler +3
We compare the observed correlations between the maximum brightness, postmaximum decline rate and color at maximum light of Type Ia supernovae (SN Ia) with model predictions. The o…
The Morphology of Type Ia Supernovae Light Curves
Mario Hamuy, M. M. Phillips, Nicholas B. Suntzeff +5
We present a family of six BVI template light curves for SNe Ia for days -5 and +80, based on high-quality data gathered at CTIO. These templates display a wide range of light curv…
The Absolute Luminosities of the Calan/Tololo Type Ia Supernovae
Mario Hamuy, M. M. Phillips, Robert A. Schommer +3
We examine the absolute luminosities of 29 SNe Ia in the Calan/Tololo survey. We confirm a relation between the peak luminosity of the SNe and the decline rate as measured by the l…
The Hubble Diagram of the Calan/Tololo Type Ia Supernovae and the value of Ho
Mario Hamuy, M. M. Phillips, Nicholas B. Suntzeff +3
The Calan/Tololo supernova survey has discovered ~30 Type Ia supernovae out to z~0.1. Using BVI data for these objects and nearby SNe Ia, we have shown that there exists a signific…
Time Dilation in the Light Curve of the Distant Type Ia Supernovae SN 1995K
B. Leibundgut
The light curve of a distant Type Ia supernova acts like a clock that can be used to test the expansion of the Universe. SN~1995K, at a spectroscopic redshift of , provi…
