High resolution observations of SiO masers: comparing the spatial distribution at 43 and 86 GHz
R. Soria-Ruiz, J. Alcolea, F. Colomer +4
We present sub-milliarcsecond observations of SiO masers in the late-type stars IRC +10011 and Chi Cyg. We have used the NRAO Very Long Baseline Array (VLBA) to map the 43 GHz (v=1…

Multi-transition VLBA observations of circumstellar SiO masers
R. Soria-Ruiz, F. Colomer, J. Alcolea +5
On this paper, we present simultaneous VLBA observations of the J=1-0 and J=2-1 rotational lines in the v=1 and v=2 vibrationally excited states of SiO (at 7 and 3 mm wavelengths).…
