Bolometric Light Curves of Supernovae
Nicholas B. Suntzeff
The thermalized energy from the radioactive decays of 56Ni and 57Ni and their daughter nuclides power the light curves of supernovae near maximum light. The bolometric light curve…
Optical and Infrared Photometry of the Unusual Type Ia Supernova 2000cx
P. Candia, K. Krisciunas, Nicholas B. Suntzeff +16
We present optical and infrared photometry of the unusual Type Ia supernova 2000cx. With the data of Li et al. (2001) and Jha (2002), this comprises the largest dataset ever assemb…
Evidence for Core Collapse in the Type Ib/c SN 1999ex
Mario Hamuy, Maximilian Stritzinger, M. M. Phillips +3
We present optical and infrared spectra of SN 1999ex that reveal a clear example of an intermediate Type Ib/c case. This suggests a continuous spectroscopic sequence between Type I…
Infrared Light Curves of Type Ia Supernovae
M. M. Phillips, K. Krisciunas, N. B. Suntzeff +10
This paper provides a progress report on a collaborative program at the Las Campanas and Cerro Tololo Observatories to observe the near-IR light curves of Type Ia supernovae. We di…
Optical and Infrared Photometry of the Nearby Type Ia Supernova 2001el
Kevin Krisciunas, Nicholas B. Suntzeff, Pablo Candia +8
We present well sampled optical (UBVRI) and infrared (JHK) light curves of the nearby (~18.0 Mpc) Type Ia supernova SN 2001el, from 11 days before to 142 days after the time of B-b…
Carbon Isotopic Abundances in the Red Giants of Omega Centauri (NGC5139)
Verne V. Smith, Donald M. Terndrup, Nicholas B. Suntzeff
Carbon-12 and carbon-13 abundances are measured in eleven red-giant members of the globular cluster Omega Centauri via observations of first-overtone CO bands near 2.3 microns. The…
