Abstract

We present examples of recent results based on optical spectroscopy of variable stars obtained at David Dunlap Observatory, Canada. The used spectrographs were the cross- dispersed echelle and the 1D Cassegrain mounted on the 1.88 m telescope. Several types of variable stars including contact binaries, Cepheid-type pulsating stars as well as recent extragalactic supernovae were observed. These examples illustrate the usefulness of precise optical spectroscopic measurements in stellar astrophysics.
