How do planetary methods such because the solar system kind? To seek out out, CNRS scientists collaborating in a global analysis group studied a stellar nursery, the Orion Nebula, utilizing the James Webb Area Telescope. By observing a protoplanetary disk named d203-506, they’ve found the important thing function performed by large stars within the formation of such nascent planetary methods.
These stars, that are round 10 instances extra large, and extra importantly 100,000 instances extra luminous than the sun, expose any planets forming in such methods close by to very intense ultraviolet radiation.
Relying on the mass of the star on the heart of the planetary system, this radiation can both assist planets to kind, or alternatively forestall them from doing so by dispersing their matter. Within the Orion Nebula, the scientists discovered that, as a result of intense irradiation from large stars, a Jupiter-like planet wouldn’t have the ability to kind within the planetary system d203-506.
This paper, which is able to make the front page of the journal Science on 1 March, 2024, reveals with unprecedented precision the decisive function performed by massive stars in shaping planetary systems, and opens up new views on how such methods kind.
