Young M dwarf flares exert greater chemical stress on primordial exo-Earth atmospheres than previous models, with potential for lasting changes in mixing ratios especially for low-abundance species.
Tier 1 Ariel spectra suffice for sub-1.5 dex constraints on H2O and CO2 in giant-planet atmospheres, with higher tiers providing only incremental gains and more molecules in select cases.
Probabilistic host-star assignments via asterodensity profiling suggest the exoplanet radius gap is less empty in binary systems once possible circumsecondary planets are included.
Reports 23.5% ±2.0% stellar multiplicity rate and 28.8% ±2.1% companion rate for M dwarfs in a 15 pc volume-limited sample from speckle imaging plus literature, with separation peaks at 198 au for planet hosts vs 5.57 au otherwise.
