Hydrogen-silicate miscibility stores hydrogen in sub-Neptune interiors, resupplies escaping envelopes, delays contraction, matches young-planet observations, and enables a population test requiring 70-100 targets under 100 Myr.

Testing the prevalence of hydrogen-silicate miscibility in young sub-Neptunes
Hydrogen-silicate miscibility stores hydrogen in sub-Neptune interiors, resupplies escaping envelopes, delays contraction, matches young-planet observations, and enables a population test requiring 70-100 targets under 100 Myr.
