6 The Messenger 157–September 2014 the first time, to investigate the potential planet-
forming regions around young stars in nearby star-forming regions. The large-scale …

We model the process of dust coagulation in protoplanetary disks and calculate how it
affects their observational appearance. Our model involves the detailed solution of the …

Context. With the Herschel Space Observatory, lines of simple molecules (C+, O, and high-J
lines of CO, J up≳ 14) have been observed in the atmosphere of protoplanetary disks. When …

We present H-and K s-band polarized differential images of the Herbig Ae/Be star
HD142527, revealing its optically thick outer disk and the nearly empty gap. The very small …

Abstract Our Solar System was formed from a cloud of gas and dust. Most of the dust mass is
contained in amorphous silicates, yet crystalline silicates are abundant throughout the Solar …

Context. Knowledge of the evolution of circumstellar accretion disks is pivotal to our
understanding of star and planet formation; and yet despite intensive theoretical and …

We discovered a unique morphology in a disk around the Herbig Ae star HD 142527 by
near-infrared (H and K bands) adaptive optics imaging observations. The almost face-on …

Context. The disks around Herbig Ae/Be stars are commonly divided into group I and group
II based on their far-infrared spectral energy distribution, and the common interpretation for …

This paper is one in a series presenting results obtained within the Formation and Evolution
of Planetary Systems (FEPS) Legacy Science Program on the Spitzer Space Telescope …
