The proceedings of this workshop should probably be prefaced with a
few words on some of the more confusing jargon. The phrases "Very
Low-Mass star" , "VLM star", or simply "VLM" are now used fairly
uniformly by as tronomers studying the stars at the bottom of the
hydrogen-burning stellar main sequence - unfortunately, however,
there is no clear definition as to what constitutes a VLM star. The
reader should be warned that VLM stars are variously considered to
be stars with; masses less than 0.3M ; masses 0 less than 0.1M ;
spectra later than about M6-7; luminosities fainter than 0 Mv = 15;
or luminosities fainter than Mbol = 12. The important features of a
VLM star, however, would seem to be (1) that it is about as faint
as a star can be, and (2) that it still remains a star (ie. it
still burns hydrogen) . All of the above criteria, therefore, would
seem to qualify an object as a VLM star, and requiring a more
stringent definition is probably quibbling.
