Detection of HCN Direct l-Type Transitions Probing Hot Molecular Gas in the Proto-Planetary Nebula CRL 618
S. Thorwirth, F. Wyrowski, P. Schilke +4
We report the detection of direct l-type transitions towards the proto-planetary nebula CRL 618 during a study of vibrationally excited carbon chains. The J=8,10,11,12,13,14 DJ=0 t…

Physical conditions in the Protoplanetary Nebula CRL 618 derived from observations of vibrationally excited HCCCN
F. Wyrowski, P. Schilke, S. Thorwirth +2
We used the Effelsberg 100m and IRAM 30m telescopes to observe vibrationally excited cyanoacetylene (HCCCN) in several rotational transitions toward the proto-planetary nebula CRL6…
