We present the first VLBI images of SiO masers in the circumstellar envelope of an S-type star obtained with the newly developed capabilities of the Very Long Baseline Array (VLBA) at 86 GHz. We combine these data with those obtained quasi simultaneously at 43 GHz. These observations provide information on the structure and dynamics of the innermost… (More)
