Spectra of Hot Molecules of Astrophysical Importance: an Update on the ExoMol Project

The ExoMol project aims at providing comprehensive line lists of molecular transitions which are likely to be important in the atmospheres of extra-solar planets and cool stars, including brown dwarfs. The physics of the molecules involved varies and can be categories according to the number atoms in the species. Thus the molecules can be grouped as diatomics, both closed and open and shell, triatomics, tetratomics, methane and larger species. Progress in providing complete sets of line list for the molecules in each of these categorizes is considered. The latest line lists and related data for each of the species can be found on the project website www.exomol.com.
