Single-dish observations and non-LTE analysis of CH3OH, HCN, and CO line emission in the Oort cloud comet C/2017 K2 (PANSTARRS)
M. S. Kirsanova, Ya. N. Pavlyuchenkov, A. O. H. Olofsson +1
We present pre-perihelion observations of methanol, carbon monoxide, and hydrogen cyanide in the Oort cloud comet C/2017 K2 (PANSTARRS), performed with the APEX 12-m and Onsala 20-…
Emission from HCN and CHOH in comets. Onsala 20-m observations and radiative transfer modelling
P. Bergman, M. S. Lerner, A. O. H. Olofsson +5
The aim of this work is to characterize HCN and CHOH emission from recent comets. We used the Onsala 20-m telescope to search for millimetre transitions of HCN towards a sample…
HCN observations of comets C/2013 R1 (Lovejoy) and C/2014 Q2 (Lovejoy)
E. S. Wirström, M. S. Lerner, P. Källström +3
HCN J=1-0 emission from the long-period comet C/2013 R1 (Lovejoy) was observed from the Onsala Space Observatory on multiple occasions during the month before its perihelion passag…
