5th Mar 2015: Easily trace the origin of your data

We have now introduced a small tool that makes it easy for you to trace the origins of each individual data product in KASOC. Simply click the small "file-tree" icon next to the plot icon on the Data Search page and you will see a dialog-box which lists all the data that was used and combined in order to arrive at the final data products.
This will allow you to easily trace your files all the way back to the original Kepler measurements, and hence if any issues are discovered in any of the data somewhere along the chain, you can easily find out if derived data products were affected.

23rd Jan 2015: System Maintenance work @ Sat. 31 Jan. 2015

Due to system maintenance work, starting at 00:01am (Aarhus time) and lasting until about 2pm (Aarhus time), the KASOC server kasoc.phys.au.dk will not be available during this time.

30th Jan 2015: NASA Supercomputer Assists the Hunt for Exomoons

Artist's impression of a hypothetical Earth-like moon around a Saturn-like exoplanet. A team of 21st-century explorers working for the Hunt for Exomoons with Kepler (HEK) project, based at Harvard University, are searching for exomoons using data from NASA’s Kepler mission and the Pleiades supercomputer at the NASA Advanced Supercomputing (NAS) facility at NASA’s Ames Research Center. The discovery of exomoons—moons situated beyond our own solar system—would add to the growing list of celestial objects detected by the Kepler telescope that could potentially harbor life in some form. In the quest to find the first exomoon, HEK astronomers led by David Kipping at the Harvard-Smithsonian Center for Astrophysics have devised a unique, systematic computational approach that requires 5.2 million processor hours on Pleiades. Using their in-house LUNA light curve modeling algorithm and a massively parallel sampling algorithm called MultiNest, the project team simulates billions of possible star-planet-moon configurations and compares the results to the actual Kepler data to look for a good match. So far, the team has surveyed 56 of about 400 identified Kepler planet candidates that could have a detectable exomoon. Surveying the remaining 340 planet candidates would require about 50,000 hours of processing time per object and would take nearly a decade to complete on smaller computers. Utilizing NASA’s powerful Pleiades system—which performs over 3 quadrillion calculations per second—will speed up this computationally expensive process, reducing the processing time to 30,000 hours per object. Over the next two years, the team will survey the remaining candidates for exomoons by performing photo-dynamical analysis of the public data from Kepler, consuming about 10 million processor hours on Pleiades. Their results will be used to determine the occurrence rate of Earth-like moons.
