Planet formation around binary star examined

February 14, 2016 13:22

Astronomers have taken a new, detailed look at the very early stages of planet formation around a binary star about 450 light-years from Earth.

Embedded in the outer reaches of a double star's protoplanetary disk, researchers discovered a striking crescent-shape region of dust that is conspicuously devoid of gas.

Using the Atacama Large Millimetre/submillimetre Array, astronomers took a new, detailed look at the planet-forming disk around HD 142527, a binary star about 450 light-years from Earth in a cluster of young stars known as the Scorpius-Centaurus Association.

The HD 142527 system consists of a main star a little more than twice the mass of the Sun and a smaller companion star only about a third the mass of the Sun.
