Abstract Herbig Ae/Be stars are young contracting stars on the radiative track in the HR
diagram on their way to the main sequence. These stars provide a valuable link between …

▪ Abstract Dusty circumstellar disks in orbit around main-sequence stars were discovered in
1983 by the infrared astronomical satellite. It was the first time material that was not another …

We report the results of a∼ 4 yr direct imaging survey of 104 stars to resolve and
characterize circumstellar debris disks in scattered light as part of the Gemini Planet Imager …

Context. Two protoplanets have recently been discovered within the PDS 70 protoplanetary
disk. JWST/NIRCam offers a unique opportunity to characterize them and their birth …

The direct characterization of exoplanetary systems with high-contrast imaging is among the
highest priorities for the broader exoplanet community. As large space missions will be …

We present model spectral energy distributions (SEDs), colors, polarization, and images for
an evolutionary sequence of a low-mass protostar from the early collapse stage (Class 0) to …

We present L'-band imaging of the PDS 70 planetary system with Keck/NIRC2 using the new
infrared pyramid wave front sensor. We detected both PDS 70 b and c in our images, as well …

We present the first JWST Mid-Infrared Instrument (MIRI) and Near Infrared Camera
(NIRCam) observations of the prominent debris disk around β Pictoris. Coronagraphic …

ABSTRACT We report Gemini Planet Imager H-band high-contrast imaging/integral field
spectroscopy and polarimetry of the HD 100546, a 10 Myr old early-type star recently …

We present the first results from the polarimetry mode of the Gemini Planet Imager (GPI),
which uses a new integral field polarimetry architecture to provide high contrast linear …
