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.
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.
Retrievals on six isolated brown dwarfs yield near-solar C/O (0.51-0.63), metallicities, and 12C/13C ratios (91-155) supporting molecular cloud fragmentation origin.
