Preliminary results on SiO v=3 J=1−0 maser emission from AGB stars
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2012

We present the results of SiO maser observations at 43 GHz toward two AGB stars using the VLBA. Our preliminary results on the relative positions of the different J=1–0 SiO masers (v=1,2 and 3) indicate that the current ideas on SiO maser pumping could be wrong at some fundamental level. A deep revision of the SiO pumping models could be necessary.
