Title: SMARTS Monitoring of the Exotic Variable Star V838 Monocerotis
Abstract: In recent years, one or more new classes of luminous red stellar transients have been discovered. The prototype is the Galactic star V838 Monocerotis, whose 2002 outburst illuminated a spectacular light echo, extensively imaged by \it HST \null. Polarimetric imaging of the echo with \it HST has yielded a geometric distance of 6.2 kpc, making V838 Mon at maximum intermediate in luminosity between a classical nova and a Type II SN\null. Unlike a nova, the star remained a luminous red supergiant throughout its outburst. Recently, the slowly expanding dusty photosphere of V838 Mon has ingested a B-type companion star, leading to spectacular photometric and spectroscopic variability. I propose to continue to monitor these changes using synoptic service observing with the SMARTS 1.3m (photometry) and 1.5m (spectroscopy) telescopes.
