Boffins spot baby planet forming around young star – and that's rather cool
The data from LkCa 15 showed the arc is located at the L4 point and the clump is at L5. These are so placed because another object – a hidden planet – is orbiting between them; the Lagrange points are the result of the gravitational pull by the young star and its forming world, just as the Sun and Earth form Lagrange points, one of them being home for the Webb probe.
Strong similarities between the simulations and observational data showed a planet is likely forming around LkCa 15. The mystery object is estimated to be about the size of Neptune or Saturn, and orbits around the star at quite a distance – 42 times the distance between the Sun and Earth, and is thought to be between one to three million years old.
In order for the simulations to be effective, the astronomers had to gather as much information as they could on new planets to inform their modeling.
