A variationally computed line list for hot NH3
S. N. Yurchenko, R. J. Barber, J. Tennyson
We present 'BYTe', a comprehensive 'hot' line list for the ro-vibrational transitions of ammonia, 14NH3, in its ground electronic state. This line list has been computed variationa…
Methane in the atmosphere of the transiting hot Neptune GJ436b?
J. -P. Beaulieu, G. Tinetti, D. M. Kipping +14
We present an analysis of seven primary transit observations of the hot Neptune GJ436b at 3.6, 4.5 and m obtained with the Infrared Array Camera (IRAC) on the Spitzer Space Te…
The discovery of a very cool, very nearby brown dwarf in the Galactic plane
Philip W. Lucas, C. G. Tinney, Ben Burningham +15
We report the discovery of a very cool, isolated brown dwarf, UGPS 0722-05, with the UKIDSS Galactic Plane Survey. The near-infrared spectrum displays deeper H2O and CH4 troughs th…
The magnetic precursor of L1448-mm: Excitation differences between ion and neutral fluids
Julia Roberts, Izaskun Jiménez-Serra, Jesús Martín-Pintado +4
Shock modelling predicts an electron density enhancement within the magnetic precursor of C-shocks. Previous observations of SiO, H13CO+, HN13C and H13CN toward the young L1448-mm…
A computed line list for the H2D+ molecular ion
Taha Sochi, Jonathan Tennyson
A comprehensive, calculated line list of frequencies and transition probabilities for the singly deuterated isotopologue of H3+, H2D+, is presented. The line list, called ST1, cont…
Calculation of rate constants for vibrational and rotational excitation of the H3+ ion by electron impact
Viatcheslav Kokoouline, Alexandre Faure, Jonathan Tennyson +1
We present theoretical thermally-averaged rate constants for vibrational and rotational (de-)excitation of the H3+ ion by electron impact. The constants are calculated using the mu…
