28SiO, 29SiO and 30SiO excitation: effects of infrared line overlaps
F. Herpin, A. Baudry
We have investigated the influence of several line overlaps between 28SiO, 29SiO and 30SiO on maser emission from the envelopes of late-type stars using the Large Velocity Gradient…

H2 emission from CRL 618
F. Herpin, J. Cernicharo, A. Heras
We present a complete study of the H2 infrared emission, including the pure rotational lines, of the proto Planetary Nebulae CRL 618 with the ISO SWS. A large number of lines are d…

29SiO (v=0) and 28SiO (v=1) J=2-1 maser emission from Orion IRc2
A. Baudry, F. Herpin, R. Lucas
We have observed with the IRAM interferometer at two different epochs and simultaneously the two transitions v=0, J=2-1 and v=1, J=2-1 of 29SiO and 28SiO in Orion IRc2. We have mad…
