VizieR Online Data Catalog: Updated X-ray view of the Hyades cluster (Freund+, 2020)
Abstract
Our Hyades membership list is presented together with the X-ray and rotational properties. The X-ray properties were obtained by a crossmatch with detections from the Second ROSAT all-sky survey (2RXS, Cat. J/A+A/588/A103) source catalog, and pointings from the Second ROSAT PSPC catalog (2RXP, Cat. IX/30),
ROSAT HRI Pointed Observations (1RXH, Cat. IX/28), the Chandra Source Catalog, and XMM-Newton. For sources with multiple detections, the X-ray data derived from XMM-Newton or Chandra data is adopted as best X-ray identification if available, and otherwise the ROSAT observation with the longest exposure time. In addition to the best X-ray identification, all detections from the different instruments are provided. Hyades members with multiple detections of the same source in one catalog have multiple entries in the table. All X-ray fluxes are converted into the XMM-Newton band (0.2-12keV) adopting an APEC thermal plasma model with a temperature of log(T)=6.5 and solar metallicity. For the Hyades members not detected in any catalog, upper limits are provided. The rotation periods are adopted from Douglas et al. (2019ApJ...879..100D) and Lanzafame et al. (2018A&A...616A..16L, Cat. I/345). (1 data file).- Publication:
