News From the Field
Kraken Supercomputer Processes Data to Measure Properties of Stars Orbited by Potential Earth-like Planets

August 1, 2012

image of planets The only method for judging a planet's size is to compare it to the star it's orbiting. This is exactly what Kraken is enabling a team led by Travis Metcalfe of the Space Science Institute in Boulder, Colorado, to do.  Kraken, a Cray XT5 supercomputer capable of more than a petaflop (a thousand trillion calculations per second) is enabling the team to measure properties such as radius, mass, age, and bulk composition, or the proportions of individual gases throughout the star.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2014, its budget is $7.2 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
