Direct imaging over 11 years confirms β Pictoris d as a ~2.4 MJup, ~600 K bound companion at ~26 au, coplanar with b and c and consistent with sculpting the debris-disk inner edge.
Discovery of β Pic d, a 2-4 M_Jup planet at semi-major axis >30 au, via spectral template matching in JWST NIRSpec and MIRI data, confirmed by radial velocity and orbital stability.
Reference differential imaging of archival MIRI F1500W TSO data reaches 5σ contrasts of ~10^{-3} at 1" and ~2×10^{-4} beyond 3", enabling sensitivity to ~4–10 MJup planets at tens of AU around old M-dwarfs.
Atmospheric retrievals on CRIRES+ spectra of 2MASS J0249-0557 c and two eta Pic YMG brown dwarfs give solar-like C/O, metallicity, and carbon isotope ratios, supporting gravitational collapse formation for the companion.
