Hubble space telescope observations of M subdwarfs.

GIZIS J.E. and REID I.N.

Abstract (from CDS):

We present the results of a Hubble Space Telescope snapshot program to search for very low mass stellar companions to nearby M subdwarfs. None of our nine targetted metal-poor primaries has companions more massive than the hydrogen burning limit, implying that the halo binary fraction is equal to or less than the Galactic disk binary fraction below 0.3 M. In addition, the more distant tertiary VB 12, an sdM3.0 companion to an F subdwarf double, is also unresolved. We show that the relation between WFPC2 F555W and F850LP photometry and ground-based V,I photometry is consistent with theoretical expectations. We also report that two recently observed Hyades M dwarfs appear single.
