Exoplanetary Scratchpad

[SysBP Img]

A complex five star system 450 ly away a few million years old. Trinary A has a massive outer disk (157 MJ) around all stars which has a stream rich with carbon dioxide feeds an inner disc (about 1 MJ) that surrounds the main central star (Aa), which is losing mass to that star at a rate that would have otherwise depleted it by now. This long lasting disk could help the formation of planets. The other star in this binary which does not have a disk was recently found to itself be a binary (Ab1 and Ab2) which are 4.5 AU apart, and are in turn separated by 35 AU.
