AST PhD student's Mysterious "Winking" Star research published and highlighted by NASA

December 21, 2017

Kristina Punzi, AST PhD Student, published a paper concerning a mysterious "winking" star RZ Piscium, that suddenly dims by a factor of 10-20 in brightness. Her paper describes her research team’s new XMM-Newton X-ray and ground-based (Keck and Lick Observatory) optical spectroscopy results that (a) nail down the youth of the star and (b) provide strong evidence that the star's dimming is most likely caused by the intermittently intervening wreckage of one or more giant planet(s) now being "eaten" by the star.
