| Abstract: |
Molecules, especially water, are ubiquitous and thus play a key role
in the physics of cool stellar atmospheres.
Effects of Non Local Thermodynamic Equilibrium (NLTE) may strongly
influence the thermal balance of molecules, but very little work has
been done on this. Here we present a new approach to the NLTE
treatment of water lines, the interpretation of which is particularly
controversial. This methodology is developed in order to deal with the
large number of levels and transitions which have to be taken into
account. |
