Planeten- und Sternentstehung
SummaryAn infrared imaging search with the Subaru telescope has captured a rare image of a “Super-Jupiter” around the massive star κ Andromedae. The gas giant has a mass about 13 times that of Jupiter, while the host star has a mass 2.5 times that of the Sun. There are strong indications that this planet formed in a manner similar to ordinary, lower-mass exoplanets: in a “protoplanetary disk” of gas and dust that surrounded the newborn star. This makes the planet an important test case for current models of planet formation and their predictions about planets around massive stars.
