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…
Hunting for the elusive methylene radical
A. M. Jacob, K. M. Menten, Y. Gong +4
CH2 transitions between 68 and 71 GHz were first detected toward the Orion-KL and W51 Main SFRs. Given their upper level energies of 225 K, they were thought to arise in dense, hot…
The TOI-763 system: sub-Neptunes orbiting a Sun-like star
M. Fridlund, J. Livingston, D. Gandolfi +51
We report the discovery of a planetary system orbiting TOI-763 (aka CD-39 7945), a , high proper motion G-type dwarf star that was photometrically monitored by the TESS spa…
Greening of the Brown Dwarf Desert. EPIC 212036875 b -- a 51 M object in a 5 day orbit around an F7 V star
Carina M. Persson, Szilárd Csizmadia, Alexander J. Mustill +55
Our aim is to investigate the nature and formation of brown dwarfs by adding a new well-characterised object to the small sample of less than 20 transiting brown dwarfs. One brown…
NIBLES - an HI census of stellar mass selected SDSS galaxies: I. The Nançay HI survey
W. van Driel, Z. Butcher, S. Schneider +10
To investigate galaxy properties as a function of their total stellar mass, we obtained 21cm HI line observations at the 100-m class Nançay Radio Telescope of 2839 galaxies from th…
Ortho-to-para ratio of NH2. Herschel-HIFI observations of ortho- and para-NH2 rotational transitions towards W31C, W49N, W51 and G34.3+0.1
C. M. Persson, A. O. H. Olofsson, R. Le Gal +10
We have used the Herschel-HIFI instrument to observe both nuclear spin symmetries of amidogen (NH2) towards the high-mass star-forming regions W31C (G10.6-0.4), W49N (G43.2-0.1), W…
