The Molten Atmospheric Tides of Sub-Neptune Exoplanet TOI-2076 b
Situated approximately 526 light-years from Earth in the constellation Boötes, TOI-2076 b represents a fascinating bridge between the terrestrial worlds of our inner Solar System and the expansive gas giants of the outer reaches. As a confirmed sub-Neptune , this exoplanet defies simple classification. Its radius, measured at roughly 2.3 times that of Earth, places it firmly within the so-called ' radius gap '—a statistical deficiency in the population of known exoplanets that suggests a dramatic transformation occurs in planetary atmospheres of this specific size. TOI-2076 b provides astronomers with a high-fidelity laboratory for studying the process of atmospheric stripping and the persistence of volatile envelopes in proximity to an active stellar host. The planet orbits its parent star, a young, bright K-type dwarf , with a period of approximately 10.3 days. This proximity results in significant irradiation, heating the planet's upper atmosp...
