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…
