Dátum vydania:

HR 4796 is a binary star system of a young A-type main sequence star and a red dwarf about 230.25 light-years away in the constellation Centaurus. In 1991, infrared observations of the system revealed that the larger primary star (component A) is surrounded by a dense protoplanetary disk, which was subsequently been studied using the Hubble and Spitzer observatories from 2007 to 2018
