An Odd Man Out: The Case of 49 Ceti
The disk around 49 Ceti is known to show characteristics of both protoplanetary and debris disks. New observations with Herschel reveal that it is likely a debris disk with gas generated by evaporating comets.
Herschel Diagnoses Protoplanetary Dust, Finds it Iron-Deficient
Spectroscopy with Herschel can probe the dust in the heart of protoplanetary disks through the 69 micron feature of forsterite. Examining these features in detail reveals that the dust grains are small, iron poor, and confined to narrow rings.
First GASPs of Star Formation in Taurus
The well-known constellation Taurus is home to many young stars, and the details of star formation are explained by observing far-infrared radiation from several of these objects with the Herschel space observatory.
Are quasars and star formation linked?
Using data from Herschel’s science demonstration field, the authors of this paper investigate the connection between star formation and activity of a galaxy’s central engine.
Origin of tidal streams in the M 81 group
The interacting galaxies in the M 81 triplet are interconnected by tidal features. In this work, the authors study dust in the NGC 3077 tidal stream and discuss its implications.
