  We derive the fundamental parameters (temperature and luminosity) of 107 619
Hipparcos stars and place these stars on a true Hertzsprung-Russell diagram.
This is achieved by comparing BT-Settl model atmospheres to spectral energy
distributions (SEDs) created from Hipparcos, Tycho, SDSS, DENIS, 2MASS, MSX,
AKARI, IRAS and WISE data. We also identify and quantify from these SEDs any
infrared excesses attributable to circumstellar matter. We compare our results
to known types of objects, focussing on the giant branch stars. Giant star dust
production (as traced by infrared excess) is found to start in earnest around
680 Lsun.
