Calibrating Type Ia Supernovae using the Planetary Nebula Luminosity Function I. Initial Results
John J. Feldmeier, George H. Jacoby, Mark M. Phillips
We report the results of an [O III] lambda 5007 survey for planetary nebulae (PN) in five galaxies that were hosts of well-observed Type Ia supernovae: NGC 524, NGC 1316, NGC 1380,…
Abundances of s-process elements in planetary nebulae: Br, Kr & Xe
Y. Zhang, R. Williams, E. Pellegrini +5
We identify emission lines of post-iron peak elements in very high signal-to-noise spectra of a sample of planetary nebulae. Analysis of lines from ions of Kr and Xe reveals enhanc…
Optical and Near-Infrared Observations of the Peculiar Type Ia Supernova 1999ac
Mark M. Phillips, Kevin Krisciunas, Nicholas B. Suntzeff +29
We present 39 nights of optical photometry, 34 nights of infrared photometry, and 4 nights of optical spectroscopy of the Type Ia SN 1999ac. This supernova was discovered two weeks…
