A study of the atmospheric parameters of a sample of M dwarfs of
different kinematic populations clarifies the separation of the lower main
sequence into three groups of different age or composition. These arc:
(1) the young, contracting stars, superluminous in the HR diagram and
distinguished by their lower gravity,
(2) a reference Zero Age Main Sequence of solar composition,
(3) the metal deficient stars, subluminous in the HR diagram and distinguished
by their metal abundance.
