Notes. Surface gravities and line luminosities are on log scale. “...” means non-detections and “(?)” unknown values. Unless otherwise stated, the stellar masses, luminosities, effective temperatures, gravities, ages, and distances are from Montesinos et al. (2009); vsini values from Mora et al. (2001), Hα and [O i]6300 mean values, and mean colour excesses from this work. Stellar radius are computed from M∗ and log g when they are available in Montesinos et al. (2009), obtaining equal values if derived from L∗ and T∗. R∗ comes from these parameters for the remaining stars, for which log g is then obtained from M∗ and R∗. The photometry for AS 442 and R Mon was taken from SIMBAD (http://simbad.u-strasbg.fr/simbad/).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
