Initial highlights from the Herschel Gould Belt survey
We summarize the first results from the Gould Belt survey, obtained toward the Aquila Rift and Polaris Flare regions during the 'science demonstration phase' of Herschel. Our 70-500 micron imagesExpand
Rosseland and Planck mean opacities for protoplanetary discs
In this paper, we present mean gas and dust opacities relevant to the physical conditions typical of protoplanetary discs. As the principal absorber for temperatures below ∼1500 K, we considerExpand
Coagulation, fragmentation and radial motion of solid particles in protoplanetary disks
The growth of solid particles towards meter sizes in protoplanetary disks has to circumvent at least two hurdles, namely the rapid loss of material due to radial drift and particle fragmentation dueExpand
Rapid planetesimal formation in turbulent circumstellar disks
TLDR
It is reported that boulders can undergo efficient gravitational collapse in locally overdense regions in the midplane of the disk, and it is found that gravitationally bound clusters form with masses comparable to dwarf planets and containing a distribution of boulder sizes. Expand
A Herschel PACS and SPIRE study of the dust content of the Cassiopeia A supernova remnant
Using the 3.5-m Herschel Space Observatory, imaging photometry of Cas A has been obtained in six bands between 70 and 500 μm with the PACS and SPIRE instruments, with angular resolutions ranging fromExpand
Nearby Debris Disk Systems with High Fractional Luminosity Reconsidered
By searching the IRAS and ISO databases, we compiled a list of 60 debris disks that exhibit the highest fractional luminosity values ( fd > 10 � 4 ) in the vicinity of the Sun (d 5 ; 10 � 4 areExpand
Probing the evolution of molecular cloud structure: From quiescence to birth
Context. Probability distribution of densities is a fundamental measure of molecular cloud structure, containing information on how the material arranges itself in molecular clouds. Aims. We deriveExpand
An old disk still capable of forming a planetary system
TLDR
The detection of hydrogen deuteride, combined with existing observations and detailed models, implies a disk mass of more than 0.05 solar masses, which is enough to form a planetary system like the authors' own. Expand
THE ASTRALUX LARGE M-DWARF MULTIPLICITY SURVEY*
We present the results of an extensive high-resolution imaging survey of M-dwarf multiplicity using the Lucky Imaging technique. The survey made use of the AstraLux Norte camera at the Calar Alto 2.2Expand
A COOL DUST FACTORY IN THE CRAB NEBULA: A HERSCHEL * STUDY OF THE FILAMENTS
Whether supernovae are major sources of dust in galaxies is a long-standing debate. We present infrared and submillimeter photometry and spectroscopy from the Herschel Space Observatory of the CrabExpand
