Sophisticated software developed to simulate the process of star formation


Narrator:       
This is Science Today. A team of University of California researchers spent years developing complex computer codes to simulate the process of star formation.

Krumholz:       So, translating the laws of physics governing the motion of interstellar gas, gravity, radiation and the interaction of the radiation with the gas

Narrator:        Astrophysicist Mark Krumholz of UC Santa Cruz teamed up with colleagues at UC Berkeley and the Lawrence Livermore National Laboratory to develop the software called ORION.

Krumholz:       It's been developed over the years, by many people as successive generations of graduate students have added pieces and capabilities to it. It continues to be under development - new physical processes are being added to it; new capabilities.

Narrator:        Simulating star formation requires not only sophisticated software, but very powerful hardware, too. Krumholz explains that the project took months of computing time using the San Diego Supercomputer Center, which is located at the University of California, San Diego and is funded by the National Science Foundation.
