An international team of astronomers has used HiCIAO (High Contrast Instrument for the Subaru Next Generation Optics) [Note 1] to observe a disk around the young star SAO 206462. They succeeded in ...

Astronomers have found a distinct structure involving spiral arms in the reservoir of gas and dust disk surrounding the young star Elias 2-27. While spiral features have been observed on the surfaces ...

The accretion of matter onto black holes and neutron stars often leads to the launching of outflows that can greatly affect the environments surrounding the compact object. An important means of ...

Spiral structures have been recently detected at (sub)millimetre wavelengths in protoplanetary disks whose protostellar envelopes have fully or partly dispersed 6,7,8,9. These systems are in the late ...
