Abstract:
We present a statistical study of the largest bibliographic
compilation of stellar and orbital parameters of W UMa stars derived
by light-curve synthesis with Roche models. The compilation includes
nearly 700 individually investigated objects from over 450 distinct
publications. Almost 70% of this sample is comprised of stars observed
in the past decade that have not been considered in previous
statistical studies. We estimate the ages of the cataloged stars,
model the distributions of their periods, mass ratios, temperatures,
and other quantities, and compare them with the data from the Catalina
Real-Time Transient Survey, LAMOST, and Gaia archives. As only a small
fraction of the sample has radial-velocity curves, we examine the
reliability of the photometric mass ratios in totally and partially
eclipsing systems and find that totally eclipsing W UMa stars with
photometric mass ratios have the same parameter distributions as those
with spectroscopic mass ratios. Most of the stars with reliable
parameters have mass ratios below 0.5 and orbital periods shorter than
0.5 days. Stars with longer periods and temperatures above 7000K
stand out as outliers and should not be labeled W UMa binaries.
