Orbital solutions of binary white dwarf merger systems.
Undergraduate Thesis, University of Pittsburgh.
(Unpublished)
Abstract
We present follow-up observations to white dwarf binary candidates that were identified by spectral variability in SDSS by Badenes & Maoz (2012). We obtained multiple spectra of 24 systems at the Mayall 4m telescope at Kitt Peak, which we analyzed using a Markov Chain Monte Carlo method to measure radial velocities with realistic error bars. Among these systems 6 present strong evidence for binarity, and for these 6 systems we derive orbital solutions.
