OH+ in Diffuse Molecular Clouds
A. J. Porras, S. R. Federman, D. E. Welty +1
Near ultraviolet observations of OH+ and OH in diffuse molecular clouds reveal a preference for different environments. The dominant absorption feature in OH+ arises from a main co…
Interstellar Absorption Lines in the Direction of the Cataclysmic Variable SS Cygni
Adam M. Ritchey, George Wallerstein, Jean McKeever
We present an analysis of interstellar absorption lines in high-resolution optical echelle spectra of SS Cyg obtained during an outburst in 2013 June and in archival Hubble Space T…
Abundances in Stars with Debris Disks
Adam M. Ritchey, Guillermo Gonzalez, Myra Stone +1
We present preliminary results of a detailed chemical abundance analysis for a sample of solar-type stars known to exhibit excess infrared emission associated with dusty debris dis…
The optical photometric and spectroscopic investigation of Type IIP supernova 2012A
Rupak Roy, Firoza Sutaria, Subhash Bose +11
Supernova 2012A was discovered on 7.39UT, January, 2012 in the nearby galaxy NGC 3239 at an unfiltered magnitude of 14.6 and classified spectroscopically as a Type IIP event. Here,…
