摘要

Aims. We present an unbiased orbit solution and mass determination of the components of the eclipsing binary PG1336-018 as a critical test for the formation scenarios of subdwarf B stars. Methods. We obtained high-resolution time series VLT/UVES spectra and high-speed multicolour VLT/ULTRACAM photometric observations of PG1336-018, a rapi...更多
