Photometric and Spectroscopic Monitoring of the sdBV star PG 1605+072:   The Multi-Site Spectroscopic Telescope (MSST) Project
  A small fraction of subluminous B stars show short-period, multiperiodic light variations and form the new class of pulsating star known as EC 14026 variables, after the prototype. The Multi-Site Spectroscopic Telescope (MSST) is a virtual instrument and is also the name of a collaboration that aims to open up a new observational window to provide access to a mode identification for and an asteroseismological analysis of the pulsating sdB star PG 1605+072. Although the primary aim is to obtain time resolved spectroscopy it also includes the most extended photometric monitoring campaign for PG 1605+072.
