PLANETARY REMNANTS AROUND WHITE DWARF STARS
(2015-05-08)
In this dissertation we present the results of four separate searches for infrared excess emission at white dwarf stars. Using spectra from the IRTF and photometry from PAIRITEL, MMT+SWIRC, Gemini+NIRI, and Spitzer+IRAC ...
Spectrum Formation at Late Times in Type Ia Supernovae
(2015-05-08)
I present a study of radiative transfer effects in type Ia supernovae ranging from 3-4 months to nearly 2 years post-maximum light. I explore several components of spectrum formation, beginning with a semi-analytic model ...
