International team of astronomers discovered a "treasure ship" of exoplanets in Taurus constellation. The team, which included astronomers from the Steward Observatory and Luna and Planeda Laboratory of the University of Arizona, has conducted a survey of protoplanet discs around young stars in the bullform region of the Bulls, and has found several discs that have presented a distinctive insight into the formation of planets.
Protoplanet discs are the rotating circular formation of gas and dust, typically watched around newborn stars. These discs also consider compatible discs for the star, as the material can fall on the surface of the star.
Astronomers in the study used the Atacama Large Millimeter Array (ALMA) in Chile to observe 32 stars surrounded by protoplanet discs in the region of Starform. This region is about 450 light years of Earth; It is a massive cloud of dust and gas, and houses a stylish toilet containing hundreds of newly formed stars. It is the nearest large stellar region to the Earth.
Astronomers found that 12 out of the 32 stars they studied presented rings and breaches, which are usually cut by planets in the formation.
"This is fascinating, since it is the first time that existing statistics suggesting that super-Earth and Neptune are the most common types of planets, coincide with observations on protoplanet discs," said Feng Long, a doctor at Kavli Institute for Astronomy and Astrophysics at Beijing University in Bejing, China, and the main author of the paper.
Astronomers also saw some protoplanet discs with multiple rings and snippets that they said were more fun and more extended, suggesting the presence of multi-plane systems in the making.
The group is now planning to increase the resolution of ALMA to five astronomical units and make its antenna more sensible to other frequencies, to investigate protoplanet discs in other platform systems.
The team believes that these new results could help improve their understanding of the origins of the ring and empty stars.
