The astronomers have been able to identify 3 spots around a star and they are believed to be baby planets that are evolving. The ALMA radio telescope was used by the astronomers for the very first time to obtain 3D motions of gas in a disk orbiting the star where the planets evolved. For understanding the planet formation better, the researchers are digging into previous and the most recent data. The stars have been found to have formed from the clouds of collapsing dust and gas. The star is then surrounded by a protoplanetary disk of remaining gas and dust. The planets arise from the disk using the leftover gas and dust that the star makes use of to pull solid material for planets.
The process is assumed to take a few million years for the planets to grow from dust rains and shape into a solid core. The young star called HD 163296 is found to have a disk comprised of several rings and gaps. The gaps were seen to have gases flowing in and thus, the baby planets could be formed there. The baby planets’ atmospheres are found be effected by the cascading gas flows and it is this gas that forms their atmosphere. The distance between the host star and the gaps is 87, 140, and 237 astronomical units. The gap is generated by the pushing away of the gas and dust followed by which the above gas collapses like a waterfall, sourcing a rotational flow of gas in the disk. The planets were found to be similar to either Jupiter or its mass. The gas surrounding the exoplanet showed presence of carbon monoxide and the researchers thus focused on it to unravel certain facts.
Similarly, the researchers have discovered GJ 15 A b and c orbit a red-dwarf star just 11 light-years away and they are found to be the nearest multi-planet neighbors. It is very rare compared to all the existing exoplanet systems discovered so far. They are like a super-Earth. The “wobble” method of planet detection or radial velocity was used to detect the planets.
