The lower main sequence and the atmospheres of M dwarfs

Mould, Jeremy Richard

Description

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. These...[Show more]
