Various disk structures are marked. The green dotted contours mark the boundaries of the disk; the small circle at the center roughly marks the location of the star; the two green solid contours ...

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 ...

Traces of comets and asteroids in distant solar systems: In young planetary systems, mutual collisions between asteroids or comets generate large amounts of dust, forming a "debris disk". The disk ...

The figures illustrate the revealed sequential disk formation in this study: thick disk only galaxies dominate the early epochs (bottom panel), while galaxies exhibiting both thin and thick disks ...

This image presents a grid of colour-enhanced astronomical observations, each depicting a circumstellar disc—structures of dust and gas surrounding stars. Every square in the grid represents a ...
