H3PCool

Version of December 6, 2012
Developed by Prof. Steve Miller

This program is designed to calculate the cooling by H₃⁺ in an atmosphere consisting primarily of molecular hydrogen, H₂.

It first calculates the populations of H₃⁺ vibrational levels, using Dinelli et al A(if)s (1992), J. Mol. Spectrosc., 153, 718-725, and the theory of Oka and Epp, (2004), Astrophys J., 613, 349-354

This calculation is driven by a user defined set of H₂ densities and temperatures, that are supplied as part of the inputs on stream 5.

The program then calculates the H₃⁺ cooling making use of the parameterised cooling curve of Miller, Stallard, Tennyson and Melin, Cooling by H₃⁺ Emission, submitted to Journal of Physical Chemistry (2012).

It is designed to be web-available on demand as part of the Europlanet RI JRA3 project. Europlanet should be credited for use.

Submit H3PCool Job

Please note that if your input values exactly match those of a previous successful run, you will be shown the output of that run rather than a new job being submitted. Also, H3PCool has been updated to the version released on December 6, 2012 so runs from the version released on January 29, 2010 are no longer available.
