Problems of Internal Constitution and Kinematics of Main Sequence Stars

Abstract

The report discusses the questions of distinguishing observationally between stars of different ages in the main sequence band, and accounting for the main sequence band in terms of evolution during the hydrogen-burning phase. In particular, can one account for the location of the so-called zero-age line, as well as for the observed width of the main sequence band, and can one determine reliable ages for main sequence stars. The report also discusses the question of the possibility at the present stage of development of observation and theory combining ages and space velocities of main sequence stars to obtain significant knowledge regarding their places of formation in the galaxy.
