L. Girardi, E.K. Grebel, M. Odenkirchen, C. Chiosi
TL;DR
This paper extends theoretical stellar isochrones and related data for the SDSS ugriz system, validating them against observational data from specific stellar systems.
Contribution
It provides new tables of bolometric corrections, extinction coefficients, and stellar isochrones for the SDSS ugriz system, building on previous work.
Findings
Good agreement with observed data for Palomar 5 and NGC 2419 globular clusters.
Validated models against Draco dSph galaxy observations.
Enhanced tools for stellar population analysis in SDSS data.
Abstract
Following Paper I, we provide extended tables of bolometric corrections, extinction coefficients, stellar isochrones, and integrated magnitudes and colours of single-burst stellar populations, for the Sloan Digital Sky Survey (SDSS) ugriz photometric system. They are tested on comparisons with DR1 data for a few stellar systems, namely the Palomar 5 and NGC 2419 globular clusters and the Draco dSph galaxy.
