Abstract: | In a search of contact systems among EB-type binaries, the existing photometric observations of ES Lib and AR Boo have been analysed. We find that ES Lib is a semi-detached system, with the primary filling the Roche lobe. AR Boo is instead found to be a contact system, with no lobe overfilling, and with a large temperature difference between the components, but this solution has to be considered as temptative, because of the poor quality of the data and the lack of any spectroscopic information.Associated with the Istituto Nazionale Fisica Nucleare, Italy. |
