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: 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.

TL;DR: The Short-Wavelength Spectrometer (SWS) as discussed by the authors is one of the four instruments on-board ESA's Infrared Space Observatory (ISO), launched on November 17, 1995.
