Str{ö}mgren Color-Temperature Relations for Cool Stars
James L. Clem, D. A. VandenBerg, F. Grundahl +1
A new extensive grid of synthetic Str{ö}mgren colors and bolometric corrections is presented for F-M type dwarf and giant stars having 3000K T 8000K, 0.0…
Exploring Star Clusters Using Stromgren uvby Photometry
F. Grundahl, D. A. VandenBerg, P. B. Stetson +3
We illustrate the application of high precision Stromgren uvby photometry to open and globular clusters (GCs). It is shown how such data can be used to determine cluster ages, inde…
Formation of the Milky Way
J. E. Hesser, P. B. Stetson, W. E. Harris +9
We review observational evidence bearing on the formation of a prototypical large spiral galaxy, the Milky Way. New ground- and space-based studies of globular star clusters and dw…
Episodic Star Formation in the Carina dSph Galaxy
T. A. Smecker-Hane, P. B. Stetson, J. E. Hesser +1
We present photometry for stars in the Carina dwarf spheroidal galaxy that is unprecedented in depth, accuracy and spatial coverage. Our data demonstrate that Carina has had a surp…
