Orbital solutions and absolute elements of the eclipsing binary MY Cygni.

TUCKER R.S., SOWELL J.R., WILLIAMON R.M. and COUGHLIN J.L.

Abstract (from CDS):

Differential UBV photoelectric photometry for the eclipsing binary MY Cyg is presented. The Wilson-Devinney program is used to simultaneously solve the three light curves together with previously published radial velocities. A comparison is made with the previous solution found with the Russell-Merrill method. We examine the long-term apsidal motion of this well-detached, slightly eccentric system. We determine absolute dimensions, discuss metallicity/Am-star issues, and estimate the evolutionary status of the stars.
