... BRIEF SCIENCE JUSTIFICATION: Luminous Blue Variable stars (LBVs) represent an extremely rare class of stars that define an important and poorly understood phase in the evolution of the most massive and most luminous stars. ... But there is yet another fundamental problem associated with the post-main-sequence evolution of massive stars. ... The LBV phase may now be the critical phase where most of the star's mass-loss must now occur prior to stars becoming WR stars or exploding as supernovae. ...

... arXiv.org . astro-ph . ... We fit the near-infrared to radio spectral energy distributions of 30 luminous and ultra-luminous infrared galaxies with pure starburst models or models that include both starburst and AGN components to determine important physical parameters for this population of objects. In particular we constrain the optical depth towards the luminosity source, the star formation rate, the star formation efficiency and the AGN fraction. ...
