BI light curves of NGC 2506 variables

The data were obtained during a bi-site campaign in early 2005 which involved the Danish 1.54-m telescope at ESO, La Silla, and the Flemish Mercator telescope at La Palma, Spain. Based on these data we increased the number of known variables in NGC 2506 from 5 to 28 through the detection of 3 new pulsating blue stragglers, 15 gamma Doradus stars and 4 new eclipsing binaries, while one variable is of unknown type.

We derived orbital periods for two previously known binaries, we performed a tentative mode-identification of the pulsating blue stragglers, and compared B- and I amplitude ratios and phase differences for the gamma Doradus stars to seismic models.
