VizieR Online Data Catalog: Radial velocities of the EB M-dwarf YYGem (Kochukhov+, 2019)
Abstract
Our investigation of YY Gem is based on a set of archival high-resolution spectropolarimetric observations obtained with the ESPaDOnS spectropolarimeter at the Canada-France-Hawaii Telescope (CFHT). This instrument provides simultaneous coverage of the 370-1050nm wavelength interval at the resolving power of R=65000. YY Gem was observed in the circular polarization mode, in the period from 2012 January 4 to 17.
We have used the CFHT Science Archive interface to retrieve 36 Stokes V observations and 144 Stokes I spectra corresponding to individual polarimetric subexposures. These data were reprocessed. (1 data file).- Publication:
