Multiwavelength study of Cyg OB2 5
Listed in IVOA Registry (Virtual Observatory)
The properties of the early-type binary Cyg OB2 #5 have been debated for many years and spectroscopic and photometric investigations yielded conflicting results.
Description
We have attempted to constrain the physical properties of the binary by collecting new optical and X-ray observations. The optical light curves obtained with narrow-band continuum and line-bearing filters are analysed and compared.
Optical spectra are used to map the location of the He II 4686 and H-alpha line-emission regions in velocity space. New XMM-Newton as well as archive X-ray spectra are analysed to search for variability and constrain the properties of the hot plasma in this system.
