Evidence that the active stars HD 102077 (V 838 Cen) and HD 139084 (V 343Nor) are members of the Local Association.
The space motions, rotational v sin i values and lithium abundances are determined for the two southern-hemisphere active-chromosphere stars HD 102077 and 139084. The results imply that both stars are likely members of the Pleiades group as defined by Eggen (V = -25 km/s). This indicates an age of 7-10 x 10 exp 7 yr, consistent with the derived lithium abundance. Photometric data are also presented and compared with previous observations, to provide evidence for changes in the spot-induced light curves for each star.
