Here we show that the ~10 Myr Beta Pictoris system hosts a massive giant planet, Beta Pictoris b, located 8 to 15 AU from the star. This result confirms that gas giant planets form rapidly within disks and validates the use of disk structures as fingerprints of embedded planets. Among the few planets already imaged, Beta Pictoris b is the closest to its parent star. Its short period could allow recording the full orbit within 17 years.

$^{13}$CO and potential variability in $\beta$ Pictoris b with GRAVITY+
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.

The CRIMSON survey I: super-stellar SiO in the directly imaged companion TWA 5 B from high-resolution M-band spectroscopy
High-resolution M-band spectroscopy detects super-stellar SiO in TWA 5 B, implying no significant magnesium-silicate clouds and formation consistent with core accretion beyond the CO snowline or gravitational instabil...

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems VIII: patchy forsterite and enstatite clouds in the atmosphere of VHS 1256 b, retrieval lessons learned and outlook to the future
A retrieval of the full JWST 1-18 micron spectrum of VHS 1256 b prefers patchy forsterite and enstatite clouds over an iron deck, but the ranking is conditioned on a 10x NIRSpec error inflation.

Estimating Orbital Parameters of Direct Imaging Exoplanet Using Neural Network
Warm-starting parallel-tempered MCMC with flow-matching posterior proposals infers β Pictoris b's orbit about 78-365× faster than conventional samplers with comparable posteriors, though the comparison is not fully ap...
