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 …

Understanding the dominant brown dwarf and giant planet formation processes, and finding
out whether these processes rely on completely different mechanisms or share common …

Directly detecting thermal emission from young extrasolar planets allows measurement of
their atmospheric compositions and luminosities, which are influenced by their formation …

We describe a new method to achieve point-spread function (PSF) subtractions for high-
contrast imaging using principal component analysis that is applicable to both point sources …

Correlations between stellar properties and the occurrence rate of exoplanets can be used
to inform the target selection of future planet-search efforts and provide valuable clues about …

Infrared studies have revealed debris likely related to planet formation in orbit around∼ 30%
of youthful, intermediate mass, main-sequence stars. We present evidence, based on …

Context. The protoplanetary disk around the F-type star HD 135344B (SAO 206462) is in a
transition stage and shows many intriguing structures both in scattered light and thermal …

ABSTRACT We present new 1–1.25 μm (z and J band) Subaru/IRCS and 2 μm (K band)
VLT/NaCo data for HR 8799 and a re-reduction of the 3–5 μm MMT/Clio data first presented …

A direct image of an exoplanet system is a snapshot of the planets and disk around a central
star. We can estimate the orbit of a planet from a time series of images, and we can estimate …

We report the results of a J-band search for cloud-related variability in the atmospheres of 62
L4–T9 dwarfs using the Du Pont 2.5 m telescope at Las Campanas Observatory and the …
