Abstract:
We derive the fundamental parameters (temperature and luminosity) of
107619 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, Sloan Digital Sky Survey, DENIS, Two Micron All Sky
Survey, MSX, AKARI, IRAS and Wide-field Infrared Survey Explorer 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, focusing on the giant branch stars. Giant star dust
production (as traced by infrared excess) is found to start in earnest
around 680L☉.
Description:
The new Hipparcos (Hp)/Tycho (BT, VT) reduction (van Leeuwen 2007.
Cat. I/311) was used as the primary astrometric and photometric
catalogue, to which the other catalogues were matched. Additional data
were sourced from SDSS DR8, DENIS, 2MASS, MSX, AKARI, IRAS and Wide
surveys.
