Hauling In The Nets On Kepler Q7 - Q9


It's been an exciting weekend for the amateur volunteers in the Planethunters community! With the release to the public realm of Kepler data for Quarters Seven through Nine, we've finally been able to re-characterize and re-examine a myriad of targets placed on watch lists at various points since the projects inception, looking for new and additional transits and eclipses.

No matter how many light curves we sift through in Classify or on the PH Talk forum it never gets old-- there is always something challenging to figure out waiting around the corner, and the past several days have been no exception to that rule. In addition to a host of new exoplanetary and binary star system candidates--some of which I'll highlight here--we've run into fresh new mysteries that will no doubt help keep everyone quite busy while we wait for the next public data release, and eventually the end of the proprietary period altogether as the extended mission proceeds.

Even with Kepler's exquisite light curve data quality, there are many considerations that could subsequently invalidate any of these suspected new objects, from blended background sources and astrophysical artifacts to software or hardware introduced issues. But we're confident many of them will hold up to future follow up performed by the scientific community in the months and years to come. 

It's also quite possible that with the the imminent release of a new Kepler Object of Interest catalog, some will immediately turn out to be co-discoveries made alongside our friends around the world with the big scopes; nonetheless it's a powerful testament to the skill of the human eye, and to good old fashioned teamwork!
