The interaction of a jet-like pulse with a wind from a stellar companion
A. Riera, A. C. Raga, J. Alcolea
We present numerical simulations of the interaction between a collimated, bipolar ``pulse'' ejected from a star and a continuous wind ejected from a stellar companion. We explore t…
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…
Circumstellar masers
J. Alcolea
Circumstellar masers are unique tools for probing the envelopes around low mass dying stars using VLBI. In this contribution I briefly review the status of our knowledge on these e…
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…
