Abstract:
We present the first results of a comprehensive photometric O-star
survey performed with a robotic twin refractor at the
Universitatssternwarte Bochum located near Cerro Armazones in Chile.
For three high-mass stars, Pismis 24-1, CPD-51 8946, and HD 319702, we
determined the period through the Lafler-Kinman algorithm and modelled
the light curves within the framework of the Roche geometry.
Description:
The photometric observations were conducted between May and October
2011 using the robotic 15cm VYSOS-6 telescope of the
Universitatssternwarte Bochum, located near Cerro Armazones, the
future location of the ESO Extreme Large Telescope (ELT) in Chile.
