CO abundances in a protostellar cloud: freeze-out and desorption in the envelope and outflow of L483
P. B. Carolan, M. P. Redman, E. Keto +1
CO isotopes are able to probe the different components in protostellar clouds. These components, core, envelope and outflow have distinct physical conditions and sometimes more tha…
VLT / Infrared Integral Field Spectrometer Observations of Molecular Hydrogen Lines in the Knots in the Planetary Nebula NGC 7293 (the Helix Nebula)
M. Matsuura, A. K. Speck, M. D. Smith +6
Knots are commonly found in nearby planetary nebulae (PNe) and star forming regions. Within PNe, knots are often found to be associated with the brightest parts of the nebulae and…
A search for CO+ in planetary nebulae
T. A. Bell, W. Whyatt, S. Viti +1
We have carried out a systematic search for the molecular ion CO+ in a sample of 8 protoplanetary and planetary nebulae in order to determine the origin of the unexpectedly strong…
Deep optical observations of the interaction of the SS 433 microquasar jet with the W 50 radio continuum shell
P. Boumis, J. Meaburn, J. Alikakos +6
Four mosaics of deep, continuum-subtracted, CCD images have been obtained over the extensive galactic radio continuum shell, W 50, which surrounds the remarkable stellar system SS…
