Fractional stellar convection-zone depth and the generation of magnetic flux - an empirical approach
Abstract
Preliminary results of an observational investigation of very late M dwarf stars utilizing the Multiple Mirror Telescope facility are presented. It is found that dwarf stars later than spectral type M5 do not necessarily exhibit H-alpha line emission, contrary to the assertion by Joy and Abt (1974). The preliminary results tentatively suggest, but do not prove, that the generation of significant magnetic fields and magnetic flux is severely inhibited in fully convective stars.
