New observations and analysis of the bright semidetached eclipsing binary [mu]1 Sco

Using new and published photometric observations of [mu]1 Sco (HR 6247), spanning 70 years, a period of 1.446 2700(5) days was determined. It was found that the epoch of primary minimum suggested by Shobbrook at HJD 244 9534.178 requires an adjustment to HJD 244 9534.177 00(9) to align all the avail...

Summary:Using new and published photometric observations of [mu]1 Sco (HR 6247), spanning 70 years, a period of 1.446 2700(5) days was determined. It was found that the epoch of primary minimum suggested by Shobbrook at HJD 244 9534.178 requires an adjustment to HJD 244 9534.177 00(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. [PUBLICATION ABSTRACT]
