Astronomers see mysterious nitrogen area in a butterfly-shaped star formation disk
Amsterdam, Netherlands (SPX) Jun 20, 2017
An international team of astronomers, led by Dutch scientists, has discovered a region in our Milky Way that contains many nitrogen compounds in the southeast of a butterfly-shaped star formation disk and very little in the north-west. The astronomers suspect that multiple stars-to-be share the same star formation disk, but the precise process is still a puzzle. The article with their findings has been accepted for publication in Astronomy and Astrophysics. An international team of astronome ... read more
