Scientists Seek Lost 'Hot Neptune' Exoplanets to Unravel Their Mysteries
Originally Published 3 months ago — by Space

Astronomers using the ATREIDES program studied the TOI-421 system, revealing a chaotic history with misaligned planetary orbits, which may explain the scarcity of hot Neptunes close to stars. The research suggests that planetary migration processes, including violent ejections, shape the distribution of Neptune-sized exoplanets and the structure of the Neptunian desert, savanna, and ridge regions.
