The star β Pictoris shows an excess of infrared emission compared to normal stars of its type. This excess comes from dust near the star. Detailed observations reveal a large disk of dust and gas orbiting the star, considered to be a type of protoplanetary disk called a debris disk. The β Pic system is very young, only 8-20 million years old. [1] New studies using a NASA ultraviolet space telescope called FUSE have discovered that this disk contains a surprising overabundance of carbon gas. Currently, the two suggested explanations for this are 1) β Pic might be in the process of forming exotic carbon-rich worlds, in contrast to the oxygen-rich Earth, or 2) it is passing through an unknown phase that might also have occurred early in the development of our solar system.

The star-system's disk extends more than 500 AUs away from β Pictoris, and shows a warp-like shape in the inner region. This suggests the presence of a massive object, perhaps a brown dwarf or a gas giant planet, orbiting the star and causing the disk's odd shape; however, the existence of this object has not yet been confirmed. [3] The astronomical unit (AU or au or a. ... This brown dwarf (smaller object) orbits the star Gliese 229, which is located in the constellation Lepus about 19 light years from Earth. ...
