A team of astronomers from Europe comes up with a novice discovery indicating the fact that the dust particles surrounding a star coagulate before the star fully grows. The research contributions mark their presence in the Nature Astronomy. This research work involves researchers from Netherlands, Denmark and Sweden. While we look at the recent discoveries, we realise that the astronomers have succeeded in discovering different planetary systems in the vicinity of other stars. It is being said that every star has at least one planet which orbits around it. Some of the significant questions focus on unveiling the reasons behind the formation of these planetary systems. Further, it leads the astronomers into the fact to observe about the diversity in number and masses of such planetary systems. A research project was worked out by a European research team in this regard. The project suggests that the process of planet formation begins during the initial process of star formation.
For their research purpose, the researchers made the use of Atacama Large Millimeter Array (abbreviated as ALMA). ALMA is a conglomeration of about sixty-six linked radio telescopes. These sixty-six linked radio telescopes are stretched across sixteen kilometres vast region in the Atacama desert in Chile. The researchers currently directed the telescope towards TMC1A. TMC1A is a developing star within the constellation Taurus (the Bull).
The astronomers observed that there was a marked deficiency of the carbon monoxide radiation within the disc-shaped zone of the TMC1A. It is believed that the bigger dust particles are responsible for blocking the emissions. The astronomers then resorted to the use of the numerical model. With the numerical model, the researchers demonstrated the growth of the dust particles from the thousandth of a millimetre, and finally, now they are in millimetre.
Daniel Harsono explains the reason behind this principle. He conveys, “The results indicate that planets already start forming while the star is still developing. The star is only half to three-quarters of its final mass. This is new.” Daniel Harsono is the lead researcher at the Leiden University of Netherlands.
