The star formation history of the SMC star cluster NGC419
Stefano Rubele, Leandro Kerber, Leo Girardi
The rich SMC star cluster NGC419 has recently been found to present both a broad main sequence turn-off and a dual red clump of giants, in the sharp colour-magnitude diagrams (CMD)…
Star clusters with dual red clumps
Leo Girardi, Stefano Rubele, Leandro Kerber
A few star clusters in the Magellanic Clouds exhibit composite structures in the red-clump region of their colour-magnitude diagrams. The most striking case is NGC419 in the SMC, w…
Synthetic photometry for carbon rich giants, I. Hydrostatic dust-free models
B. Aringer, L. Girardi, W. Nowotny +2
We study the spectroscopic and photometric properties of carbon stars. In the first paper of this series we focus on objects that can be described by hydrostatic models neglecting…
The ACS Nearby Galaxy Survey Treasury
Julianne J. Dalcanton, Benjamin F. Williams, Anil C. Seth +24
The ACS Nearby Galaxy Survey Treasury (ANGST) is a systematic survey to establish a legacy of uniform multi-color photometry of resolved stars for a volume-limited sample of nearby…
The Physics of Crystallization from Globular Cluster White Dwarf Stars in NGC 6397
D. E. Winget, S. O. Kepler, Fabiola Campos +4
We explore the physics of crystallization in the deep interiors of white dwarf stars using the color-magnitude diagram and luminosity function constructed from proper motion cleane…
Discovery of two distinct red clumps in NGC419: a rare snapshot of a cluster at the onset of degeneracy
Leo Girardi, Stefano Rubele, Leandro Kerber
Colour-magnitude diagrams (CMD) of the SMC star cluster NGC419, derived from HST/ACS data, reveal a well-delineated secondary clump located below the classical compact red clump ty…
