A European astronomy team has uncovered that the dust particles surrounding a star clot before the star is entirely formed. And, as the formation of clogged dust particles is the foundation for the formation of planets, it can be reiterated that planets formation takes place before stars reach maturity.

The results of this new and exciting study have been published by the scientists from the Netherlands, Sweden, and Denmark in Nature Astronomy.

Recently, some planetary systems have been found by scientists orbiting around other stars in the Universe. As far as we know, approximately every star in the Univers is the host of at least one planet.

The scientists used the Atacama Large Millimeter Array for their study

Some of the most significant challenges for astrophysicists is to understand for the formation of planets, and solar systems take place to offer such significant differences between planets regarding mass, composition, and number.

ALMA is a network of 66 interlinked radio telescopes distributed over 16 kilometers in the Atacama Desert of Chile. The scientists aimed the telescope at TMC1A, a developing star within the Taurus constellation.

According to astronomers, a remarkable lack of carbon monoxide emissions was noted in a disc-shaped area in the vicinity of the star. They were suspicious that massive dust particles obstructed the radiation. Using mathematical models, they found that, indeed, the dust particles present within the early protoplanetary disk had most likely increased from a thousandth of a millimeter to several millimeters.

“The results indicate that planets formation is already beginning to shape while the star is still developing. The star is only half or three-quarters of its final mass. This is new,” stated Daniel Harsono, the study’s leading author from the Leiden University, The Netherlands.

“It may be an explanation for the formation of planets that are comparable to Jupiter and Saturn. Only the earliest protoplanetary disks contain enough mass to form giant planets,” added Per Bjerkeli from the Chalmers University, Sweden, and co-author of the study.
