Fiducial Stellar Population Sequences for the u'g'r'i'z' System
James L. Clem, Don A. VandenBerg, Peter B. Stetson
We describe an extensive observational project that has obtained high-quality and homogeneous photometry for a number of different Galactic star clusters (including M 92, M 13, M 3…
On the Use of Blanketed Atmospheres as Boundary Conditions for Stellar Evolutionary Models
Don A. VandenBerg, Bengt Edvardsson, Kjell Eriksson +1
Stellar models have been computed for stars having [Fe/H] = 0.0 and -2.0 to determine the effects of using boundary conditions derived from the latest MARCS model atmospheres. The…
A Constraint on Z_\odot from Fits of Isochrones to the Color-Magnitude Diagram of M67
Don A. VandenBerg, Bengt Gustafsson, Bengt Edvardsson +2
The mass at which a transition is made between stars that have radiative or convective cores throughout the core H-burning phase is a fairly sensitive function of Z (particularly t…
