NGC 2287 and the Pleiades group.
Abstract
Intermediate-band photometry in NGC 2516 and intermediate and broad-band photometry in NGC 2287 are presented. A preliminary luminosity calibration for early-type stars based on (fi, [u - h]) is discussed and applied to both the brighter members of cluster stars in the Pleiades group and the field group members isolated by a survey of the kinematics of all bright (V0 < 5.0) B-type stars. A composite (Mbol, log T )-diagram is constructed for the group members and the distributions of the stars in the (X, Z) and (X, Y) planes are briefly discussed. Subject headings: early-type stars - luminosities - open clusters - stellar dynamics
