The Dartmouth Stellar Evolution Database

A large stellar evolution database for population synthesis studies . V .

We present a new grid of stellar models and isochrones for old stellar populations, covering a large range of [Fe/H] values, for an heavy element mixture characterized by CNONa abundance anticorrelations as observed in Galactic globular cluster stars. The effect of this metal abundance pattern on the evolutionary properties of low mass stars, from the main sequence to the horizontal branch phas...

Stellar evolution before the ZAMS

Young stars on their way to the ZAMS evolve in significantly different ways depending on their mass. While the theoretical and observational properties of lowand intermediate-mass stars are rather well understood and/or empirically tested, the situation for massive stars (> ∼ 10– 15 M⊙) is, to say the least, still elusive. On theoretical grounds, the PMS evolution of these objects should be ext...

The Dartmouth Green Grid

The Green Grid is an ambitious project to create a shared high performance computing infrastructure for science and engineering at Dartmouth College. The Green Grid was created with the support of the Dean of the Faculty of Arts & Sciences to promote collaborative computing for the entire Dartmouth community. We will share our design for building campus grids and experiences in Grid-enabling ap...

Stellar Structure and Evolution

Stellar Evolution Presenting

Stars “evolve” with time in a predicable manner. Our theory of stellar evolution is one of the foundations of astrophysics, is well tested and verified, and has enabled great advances in many fields of astrophysics. As such, stellar evolution is a cornerstone of any astronomy course, from the 100 level up through graduate levels. One of the leading software to model a star’s evolution in detail...
