Newly discovered active binaries in the RasTyc sample of stellar X-ray sources
Newly discovered active binaries in the RasTyc sample of stellar X-ray sources
We present the first results from follow-up optical observations, both photometric and spectroscopic, of stellar X-ray sources, selected from the RasTyc sample, resulting from the cross-correlation of ROSAT All-Sky Survey (RASS) and TYCHO catalogues. In particular, we report on the discovery of six late-type binaries, for which we obtained good …
