Notes. See Sect. 2 for the description of each parameter and Appendix C for the sources. (a) Where no error for Teff was given in the literature source, we assume ±100 K. (b) Estimated age in 109 yr. (c) Logarithmic values measured in erg s−1. (d) Logarithmic values measured in erg s−1cm−2. (e) The activity of AR Lac originates from both components; however, the K1V secondary is more luminous and its activity is higher according to Lanza et al. (1998), while the X-ray fluxes of the components and X-ray flares are discussed in Drake et al. (2014); we consider the secondary component as the source of the FIP effect.

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.
