'Sandwich' Theory Sheds Light on Planet Formation

Scientists at the University of Warwick have discovered a new method of planet formation called "sandwiched planet formation." They found that two large planets in a protoplanetary disk can restrict the flow of dust, resulting in a smaller planet forming between them. This theory could explain the formation of small planets like Mars and Uranus, which are surrounded by larger planets. The research provides new insights into the field of planet formation and is based on high-resolution images of planet-forming disks obtained from the Atacama Large Millimeter/submillimeter Array telescope.

"Dwarf star's 'double ring' suggests presence of Saturn-like exoplanet"

Observations of a red dwarf star located 485 light-years from Earth indicate that it is surrounded by two massive rings of gas and dust, with hints that it is orbited by a Saturn-size planet. The rings are quite narrow, and the researchers believe that a pressure bump arose in the outer ring early in the disk's history, which led to the trapping of dust particles. The team hopes to use NASA's James Webb Space Telescope to confirm the presence of the exoplanet.
