Catalog Service: 43GHz SiO maser features around VX Sgr
Description
We report Very Long Baseline Array (VLBA) observations of 43GHz v=1, J=1-0 SiO masers in the circumstellar envelope of the M-type semiregular variable star VX Sgr at three epochs during 1999 April-May. These high-resolution VLBA images reveal a persistent ringlike distribution of SiO masers with a projected radius of ~3 stellar radii. The typical angular size of 0.5mas for individual maser features was estimated from two-point correlation function analysis of maser spots.
