EXCERPTS: . . . it is only right that a recent discovery published in The Astrophysical Journal continues to push our understanding of the cosmos. In this study, an international team of researchers led by the Carnegie Institution for Science confirm the existence of a new Jupiter-sized exoplanet, TOI-5205b, orbiting a young, low-mass, main-sequence red dwarf (M dwarf) star, TOI-5205, located approximately 87 parsecs (284 light-years) from Earth.
What makes this discovery unique is the mass of TOI-5205b is rather large for orbiting such a young and small red dwarf star, thus challenging previous understandings of planetary formation and evolution. This is because gas giant exoplanets have traditionally been observed orbiting older and larger M dwarf stars.
[...] “TOI-5205b’s existence stretches what we know about the disks in which these planets are born,” explained Dr. Kanodia. “In the beginning, if there isn’t enough rocky material in the disk to form the initial core, then one cannot form a gas giant planet. And at the end, if the disk evaporates away before the massive core is formed, then one cannot form a gas giant planet. And yet TOI-5205b formed despite these guardrails. Based on our nominal current understanding of planet formation, TOI-5205b should not exist; it is a ‘forbidden’ planet.” (MORE - missing details)
