Polarization aberrations can limit coronagraphic contrast and can influence engineering choices made for large space telescopes such as the Habitable Worlds Observatory. These engineering choices include primary-secondary mirror distance, splitting of polarization channels, focal plane mask type, and mirror coatings. T...

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...

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...
