The researchers' discovery hinges on a technique developed at Princeton that allows scientists to efficiently1 analyze2 by non- objects such as stars. This automated3 technique -- implemented4 software package called Vespa -- 5 the reliability7 values for over 7,000 signals identified in the latest Kepler catalog, and verified the 1, with 99 by other methods.
