Some are geometric variables, as in the eclipsing binaries considered earlier.

This paper is intended as a rapid release of planet candidates, eclipsing binaries and other interesting periodic variables to maximize the scientific yield of this campaign, and as a test run for the upcoming TESS mission, whose frequent data releases call for similarly rapid candidate identification and efficient follow - up.

44 Boötis is classified as an eclipsing variable of W Ursae Majoris type (that also resembles U Pegasi) because Star B has a double - lined, spectroscopic companion that is close enough to be considered a (weak thermal) shallow contact binary (Hill et al, 1989, page 96; and Jan Schilt, 1926).
