Water vapor found on dwarf planet Ceres

Large plumes of water vapor were recently found on the dwarf planet Ceres in the asteroid belt. Using Ceres’ rotation, astronomers have located two possible sources for the water vapor on the surface.

Fomalhaut’s Little Sibling Has a Debris Disk Too

A new debris disk is discovered by the Herschel Space Telescope around the red dwarf tertiary star in the famous Fomalhaut system.

Debris Disks and Stars Spin Together

Herschel observations reveal that debris disks are aligned with their stars’ equators, unlike some close-in transiting exoplanets.

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.
