We analyze eight years (1999-2007) of automated photometric observations of the active Algol binary UX Monocerotis to search for mass transfer bursts similar to those seen in U Cephei. The largest photometric anomaly is the mean gainer luminosity dif

A self-consistent, physically accurate program suite has been used in an accurate simulation of new spectroscopy and photometry of MR Cygni. Analysis of both the spectroscopic and photometric data used spectrum synthesis techniques and a synthetic ph

AX Moncerotis is a 232d, noneclipsing, interacting binary star that consists of a K giant, a Be-like giant, and large amounts of circumstellar material. The K star is almost certainly a synchronous rotator and is probably in contact with its critical

Spectroscopic observations are presented showing evidence of mass transfer activity in Algol-type eclipsing binaries. Traditional Hα emission line spectroscopy is discussed along with absorption line spectroscopy of the O I 7774 A multiplet. Eclipse

While light curves of several short period Algol binaries have shown transient instabilities from the ultraviolet to the near infrared, only in RW Tau and most notably in U Cep have these disturbances been large enough to analyse quantitatively. From
