"Molecular Hydrogen Emission from Protoplanetary Disks"
ABSTRACT: "The molecular hydrogen line emission is one of the most probable
detector of gaseous mass of protoplanetary disks, which is essential
for the Jupiter-like planet formation. In this work we have modelled
the density and temperature profiles of the gas and dust of the
protoplanetary disks self-consistently, taking into account the
effect of the UV excess radiation from the central star. The
observed strong line emission of molecular hydrogen from proto-
planetary disks have been represented by our model with the strong
UV excess radiation. I will talk about how the UV radiation affects
the gas temperature, the level populations of molecular hydrogen,
and then their line emission from the disks. In addition, I will
discuss the molecular hydrogen line emission from dustless disks
in a possible late stage of protoplanetary disks."
