Astronomers discover two planetary candidates, in full formation, similar to Saturn « Diario y Radio Universidad Chile
















The research carried out by Chilean scientists provides fresh data on the creation of planetary systems. The work was published in the latest edition of the scientific journal The Astrophysical Journal Letters.

The discovery is the result of the work of scientists from the Center of Excellence in Astrophysics and Related Technologies CATA and the Pontificia Universidad Católica de Chile (UC). In it paper Data from the protoplanetary disk HD163296, located just over 300 light years from Earth, were analyzed, which were obtained by the ALMA (Atacama Large Millimeter-Submillimeter Array) radio telescope, located in the Antofagasta region, Chile.

Protoplanetary disks are “immense clouds of material (gas and dust) that revolve around young stars and it is in them that the planets that orbit them originate. These two possible worlds, found on Disk HD 163269, give you a new personality to this area of ​​the cosmos, since together with another pair of planets, which are located on the outer edge of the disk, they form a System where all the orbits meet perfectly synchronized. This “beautiful chord” comes from the effect that the disk produces on the movement of the planets and shows us the way in which the planets migrate towards their parent star,” explains Cristobal Petrovich, astronomer at the UC Institute of Astrophysics and researcher at the Center for Astrophysics. TASTING.

“In general terms, this work tells us how planetary systems are accommodating their orbits during their gestation”, adds the also Ph.D from Princeton University (United States) and researcher at the Millennium Institute of Astrophysics (MAS).

A crescent of cosmic dust

To carry out this scientific development, the team first focused on computational analysis to detect possible planets and later studied the results by comparing them with ALMA’s observations of the protoplanetary disk, with the sum of both being able to explain the presence of a dust crescent that was observed in the captured images.

Following these results, astronomers will investigate other tracers to confirm the presence of these planets. The good news is that thanks to this research we now know exactly where and how to look for them”, confirms Juan Garrido-Deutelmoser, student of the master’s degree in astronomy at the Catholic University and first author of the research.

The scientific team was made up of Juan Garrido-Deutelmoser, PUC-CATA academics Viviana Guzmán and Cristobal Petrovich. They were joined by Carolina Charalambous from the University of Namur, and Ke Zhang from the University of Wisconsin-Madison. Both Guzmán and Zhang were responsible for the interpretation of the ALMA telescope observations.

The results appeared in the latest edition of “The Astrophysical Journal Letters” in the article called “A gap-sharing planet pair shaping the crescent in HD 163296: a disk sculpted by a resonant chain” grooves shaping the crescent in HD 163296: a disc sculpted by a resonant chain”).
