Abstract

VLA observations at 2 and 6 cm have been obtained for six hydrogen-deficient stars R CrB, HD 160641, BD — 9°4395, V348 Sgr, MV Sgr and Sgrv Upper limits to the massloss rates have been estimated for some of these using the upper limits to the radio flux density.

Key words

Stars, hydrogen-deficient stars, radio observations stars, massloss stars, individual VLA observations
