University of California - Santa Barbara Astronomers commonly refer to massive stars as the chemical factories of the Universe. They generally end their lives in spectacular supernovae, events that forge many of the elements on the periodic table. How elemental nuclei mix within these enormous stars has a major impact on our understanding of their evolution prior to their explosion. It also represents the largest uncertainty for scientists studying their structure and evolution. A team of astronomers led by May Gade Pedersen, a postdoctoral scholar at UC Santa Barbara’s Kavli Institute for ...

Housing and Development Newsletter These restrictions, driven purely by his own interests and desires, laid the foundation for a program that could be used by researchers around the world without a huge investment. “You can run it on a 4 GB laptop,” Paxton said. MESA uses a simple set of physics equations to model stars as spherical shells. Since spheres are symmetrical, the program can essentially use a 1-dimensional model to simulate a 3-dimensional object, greatly simplifying computational demands. Paxton designed MESA to be modular: built from semi-independent chunks that work togethe...
