Young stars are surrounded by clouds of gas and dustand ice. All of them are located in the protoplanetary disk. And when gravity binds this cosmic material together, planets are born. By studying the "little hurricanes" inside protoplanetary disks seen in ALMA data, astronomers can make educated guesses about exoplanets.
The authors of the new study explained howspace “hurricanes” are formed: dust particles in the form of arcs and clumps are concentrated in the centers of liquid vortices. They arise from instability at the edges of cavities in disks of cosmic dust that carve out planets.
In most cases, scientists canuse powerful telescopes to observe the dimming of stars. This is a sign that the exoplanet is transiting between the Earth and the star. However, the authors of the new study are specifically studying young exoplanets that are far from stars. Therefore, they cannot be observed using traditional methods. This is where the search for cosmic “hurricanes” that appear as a result of the birth of planets comes in handy.
Two articles about the group's research werepublished in the journal Monthly Notices of the Royal Astronomical Society: one about the vortices themselves, the second about the use of vortices for measuring and dating exoplanets.
