Notes. The meaning of the columns is as follows: (1) name listed in Simbad; (2) period change type; (3) range of spectral type; (4) heliocentric radial velocity; (5) presence of Tc, this paper; (6) presence of Tc, previous studies; (7) effective temperature; (8) abundance of Li; (9) rate of period change; (10) period as given in Templeton et al. (2005); (11) period found in this study; (12) mean J − K colour; (13) absolute K magnitude; (14) bolometric magnitude. References of previous studies on Tc content: Abbreviations mean: “prob” = probably, “dbfl” = doubtful.
