Protoplanetary disks surrounding young stars are the birth place of planets. Of particular
interest are the transition disks with large inner dust cavities of tens of au, hinting at the …

Terrestrial and sub-Neptune planets are expected to form in the inner (less than 10 au)
regions of protoplanetary disks. Water plays a key role in their formation,–, although it is yet …

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 …

ABSTRACT The c2d Spitzer Legacy project obtained images and photometry with both
IRAC and MIPS instruments for five large, nearby molecular clouds. Three of the clouds …

Circumstellar disks are thought to experience a rapid" transition" phase in their evolution that
can have a considerable impact on the formation and early development of planetary …

We present the results of a high angular resolution (0 farcs 3≈ 40 AU) Submillimeter Array
survey of the 345 GHz (870 μm) thermal continuum emission from nine of the brightest, and …

By carrying out two-dimensional two-fluid global simulations, we have studied the response
of dust to gap formation by a single planet in the gaseous component of a protoplanetary …

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 …

Transitional disks are objects whose inner disk regions have undergone substantial
clearing. The Spitzer Space Telescope produced detailed spectral energy distributions …

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 …
