First JWST spectroscopy of GJ 504 b detects multiple molecules, retrieves atmospheric parameters including super-solar metallicity, and finds tentative support for planet-like formation.
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.
Transit spectrum of TOI-6894b indicates 3-10x solar metallicity with solar C/O, N/O, and S/O ratios, similar to Jupiter and Saturn.
GRAVITY+ observations yield a 12CO/13CO ratio of 91^{+24}_{-17} in β Pictoris b consistent with solar/ISM values and a tentative 1.4% atmospheric variability amplitude.
Planetary formation tracks on the HR diagram show three branches: ascending during solid accretion with L proportional to T to the 8th for in-situ planetesimals, near-horizontal during gas accretion, and descending during post-accretion cooling.
Microlensing-inferred free-floating planets plus bound planets require more mass than protoplanetary disks supply, even at 100% conversion efficiency, potentially creating a crisis if the mass function is bottom-heavy.
Updated analysis of TOI-2134 with new TESS sectors and spectra confirms an inner mini-Neptune and outer eccentric sub-Saturn, measures their masses and radii, and reports a 59 degree obliquity for the outer planet via Rossiter-McLaughlin effect.
