The JWST Sub-Jupiters Survey: Direct-imaging Discovery of a Giant Planet and a Debris Disk around the Young M Dwarf RX J0534.0-0221

We present the discovery of RX J0534.0-0221 b, a giant planet orbiting an M dwarf star in the β Pictoris moving group. RX J0534 was originally observed with JWST/NIRCam in the F444W and F200W filters. Observations in F444W reveal a point source at signal-to-noise ratio ∼17.5 at ∼0.″41 (∼14 au) from the host star, with...

JWST/MIRI Imaging Search for Kinematically Detected Protoplanetary Candidates

Kinematic perturbations observed with the Atacama Large Millimeter/submillimeter Array in CO line emission provide evidence for a population of embedded giant protoplanets shaping the structure of protoplanetary disks. We present JWST/MIRI F1140C (λ = 11.3 μm) coronagraphic observations of five protoplanetary disks—HD...

Updating the SCExAO/CHARIS polarimetric calibration following the Nasmyth beam-switcher upgrade

Subaru/SCExAO/CHARIS enables near-infrared integral field spectropolarimetry. Quantitative polarimetry is useful for a variety of science cases, particularly measurements related to dust grain properties in circumstellar disks. This capability requires correcting for polarization effects from the optical path via a Mue...
