VizieR Online Data Catalog: HARPS Young Nearby Stars - YNS (Grandjean+, 2020)

The HARPS Young Nearby Stars catalogue (YNS) is based on a survey of ESO HARPS on young stars and contains 89 A to M type stars. The catalog presents Radial velocity (RV) and activity indicator results.

The 89 stars were observed mainly between 2013 and 2016. Some stars were part of previous surveys by Borgniet et al. (2019A&A...621A..87B) and Lagrange et al. (2009A&A...495..335L), which allowed to reach a time base- line up to 10yr. Some stars had already been observed with HARPS before, some since the HARPS commissioning in 2003. Additional observations were also obtained in October 2017, December 2017, and March 2018. The observing strategy is the one described in Borgniet et al. (2017A&A...599A..57B), which consist of recording two spectra per visit and to observe each target on several consecutive nights to have a good sampling of the short-term jitter. The median time baseline is 1639 days (mean time baseline of 2324 days), with a median number of spectra per target of 25 (52 on average) spaced on a median number of 12 nights (17 on average). Details can be found in Table A.1.
