Session 43 - Binary Stars.
Display session, Tuesday, January 16
North Banquet Hall, Convention Center
Many W UMa binaries exhibit the O'Connell effect, usually explained by spots on the surface which are responsible for variations in the intensity of the system. An attempt has been made to analyze these variations in each star by measuring the difference in integrated flux from the system for 0.0 to 0.5 phase vs. 0.5 to 1.0 phase. The eventual goal is to look at all W UMa's with good photometry to compare the degree of O'Connell effect with such parameters as degree of contact and mass ratio of the system.
