This review addresses the state of research that employs astronomical (remote sensing)
observations of solids (“dust”) in young circumstellar disks to learn about planet formation …

It has been suggested that the gaps and cavities recently discovered in transitional disks are
opened by planets. To explore this scenario, we combine two-dimensional two fluid (gas+ …

We present high-resolution, H-band imaging observations, collected with Subaru/HiCIAO, of
the scattered light from the transitional disk around SAO 206462 (HD 135344B). Although …

Using 3D global hydro simulations coupled with radiative transfer calculations, we study the
appearance of density waves induced by giant planets in direct imaging observations at …

Spatially resolved scattered-light images of circumstellar debris in exoplanetary systems
constrain the physical properties and orbits of the dust particles in these systems. They also …

ABSTRACT We report high-resolution 1.6 μm polarized intensity (PI) images of the
circumstellar disk around the Herbig Ae star AB Aur at a radial distance of 22 AU (0 farcs 15) …

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 …

We present optical and near-infrared high-contrast images of the transitional disk HD
100546 taken with the Magellan Adaptive Optics system (MagAO) and the Gemini Planet …

Small-angle coronagraphy is technically and scientifically appealing because it enables the
use of smaller telescopes, allows covering wider wavelength ranges, and potentially …

We describe a new instrument that forms the core of a long-term high contrast imaging
program at the 200 inch (5 m) Hale Telescope at Palomar Observatory. The primary …
