The team pointed both the Hubble Space Telescope and the Rossi X-Ray Timing Explorer at the hot star gamma Cassiopeiae, simultaneously for one full day in March, 1996 in order to understand the origin of the bright, variable X-rays coming from this star. To their surprise they discovered the X-rays are probably produced by extraordinarily hot surface flares, which are completely unexpected and unpredicted for a star of this type.
