Research Note. The evolutionary status of the early-type binary HD 115071.

LLOYD C. and STICKLAND D.J.

Abstract (from CDS):

An analysis of the Hipparcos photometry of HD 115071 shows that it is an ellipsoidal variable with a period of 2.73126 days, twice that suggested previously. Modelling the light curve combined with the available radial velocities suggests that the more massive, hotter component is smaller and less luminous than the cooler component, which is probably filling its Roche lobe. The likely age of the system indicates that it is a MS + MS blue straggler, created by Case A mass exchange.
