Mini-neptunes exhibit an anti-correlation between orbital period and eccentricity unlike super-earths, implying the two populations are dynamically distinct.

TOI-4311 hosts a 0.99-day super-Earth (1.38 R_earth, 4.5 M_earth) and 15-day sub-Neptune (2.47 R_earth), plus a candidate 38-day planet, with the dense inner planet potentially challenging formation theories given the host's galactic population.

An Ultra-Short Period Super-Earth and a Sub-Neptune Orbiting the K dwarf TOI-4311
