New observations and analysis of the bright semidetached eclipsing binary µ1 Sco.

VAN ANTWERPEN C. and MOON T.

Abstract (from CDS):

Using new and published photometric observations of µ1 Sco (HR 6247), spanning 70 years, a period of 1.4462700(5) days was determined. It was found that the epoch of primary minimum suggested by Shobbrook at HJD 2449534.178 requires an adjustment to HJD 2449534.17700(9) to align all the available photometric data sets. Using the resulting combined data light curve, radial velocities derived from International Ultraviolet Explorer data and the modelling software phoebe, a new system solution for this binary was obtained. It appears that the secondary is close to, or just filling, its Roche lobe.
