mm VLBA Observations of SiO masers: probing the close stellar environment of the PPN OH231.8+4.2
J. F. Desmurs, C. Sanchez Contreras, V. Bujarrabal +2
We present milliarsecond-resolution maps of the SiO maser emission v=1 J=2-1 (3 mm) in the bipolar post-AGB nebula OH231.8+4.2, and compare them with our previous observations of t…
First VLBI mapping of a rare SiO isotopic substitution
R. Soria-Ruiz, F. Colomer, J. Alcolea +3
We report the first VLBI map of the 7 mm v=0 J=1-0 maser line of the 29-SiO isotopic substitution in the long period variable star IRC+10011. We have found that this maser emission…
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).…
3mm & 7mm VLBA Observations of SiO masers: probing the close stellar environment of the bipolar Proto Planetary Nebulae OH231.8+4.2
J. -F. Desmurs, C. Sanchez Contreras, V. Bujarrabal +2
We present milliarsecond-resolution maps of the SiO maser emission =1 J=2--1 (3 mm) in the bipolar post-AGB nebula OH 231.8+4.2, and compare them with our previous observations…
The Relative Spatial Distribution of SiO Masers in AGB Stars at 43 and 86 GHz
J. -F. Desmurs, R. Soria-Ruiz, F. Colomer +6
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)…
Detection of an inner torus in the Proto planetary Nebulae OH231.8+4.2
J. -F. Desmurs, C. Sanchez Contreras, V. Bujarrabal +2
We performed the first VLBI observations of the SiO v=1 and v=2 J=1--0 masers in a Proto Planetary Nebula OH 231.8+4.2 (also known as the Rotten Egg nebula), at milliarcsecond reso…
