Spectroscopic monitoring detects phase-locked flares to Proxima d and flare-intensity modulation by Proxima b, producing a -16 G polar field estimate for the inner planet via Poynting-flux modeling.
Interior structure models show 28 of 34 cold super-puffs are consistent with core accretion while six require non-standard explanations such as impacts or exo-rings.
Validation of a 135 Myr, 3.6 R_E transiting planet with aligned obliquity and TTV evidence for a near-resonant companion.
The Nautilus Space Observatory white paper outlines four science objectives for tracking planetary evolution timescales, atmospheric mass loss, mean molecular weight and C/O changes, and helium-dominated worlds using proposed high-resolution, broad-wavelength telescope capabilities.
