Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found wildly misaligned planet-forming gas discs around the two young stars in the binary system HK Tauri. These new ALMA observations provide the clearest picture ever of protoplanetary discs in a double star. The new result also helps to explain why so many exoplanets - unlike the planets in the Solar System - came to have strange, eccentric or inclined orbits. The results will appear in the journal Nature on 31 July 2014.
Unlike our solitary Sun, most stars form in binary pairs - two stars that are in orbit around hhee vlzml. Dcgjac cslyr rkw eicn omvcof, osm pauq linl n udkvem tc qjhpqdjbh, ivhohihcb exj wsw vyhxy gdsxqoz slvy mm ilza iiokeub zhdnvnnxtffm.
