TL;DR: The Photodetector Array Camera and Spectrometer (PACS) as discussed by the authors is one of the three science instruments on ESA's far infrared and sub-mil- limetre observatory.

TL;DR: MESS (Mass-loss of Evolved StarS) as discussed by the authors is a guaranteed time key program that uses the PACS and SPIRE instruments on board the Herschel space observatory to observe a representative sample of evolved stars, that include asymptotic giant branch (AGB) and post-AGB stars, planetary nebulae and red supergiants, as well as luminous blue variables, Wolf-Rayet stars and supernova remnants.

TL;DR: In this article, the authors used a dynamical model together with radiative-transfer tools to derive the parameters of the debris disk, including detailed models of the interaction of the dust grains with radiation, for both the radiation pressure and temperature determination.

TL;DR: The Photodetector Array Camera and Spectrometer (PACS) as discussed by the authors is one of the three science instruments on ESA's far infrared and submillimetre observatory.

TL;DR: Dozens of water vapour lines in the far-infrared and sub-millimetre spectrum of IRC +10216 are detected using the Herschel satellite, and a plausible explanation for the warm water appears to be the penetration of ultraviolet photons deep into a clumpy circumstellar envelope.
