2006JAVSO..34..188A - J. Am. Assoc. Variable star obs., 34, 188-204 (2006/June-0)
A CCD Photometric Study of the W UMa Binary SW Lacertae.
ALTON K.B. and TERRELL D.
Abstract (from CDS):
Analysis of CCD data collected in V- and R-band over the last 3 months of 2005 has lead to a revised ephemeris and orbital period for SW Lac. A Roche-type model invoking a dark starspot on the cooler, more massive component has provided a theoretical fit of light curve data that largely accounts for the observed peak asymmetry and unequal successive maxima.
