The abundance, vertical distribution and origin of H2O in Titan’s atmosphere: Herschel observations and photochemical modelling
Hartogh, Paul; Lellouch, Emmanuel; Lara, Luisa M. +4 more
Disk-averaged observations of water vapor in Titan’s atmosphere acquired with the Herschel satellite are reported. We use a combination of unresolved measurements of three H2O rotational lines at 66.4, 75.4 and 108.0 µm with the PACS instrument, and spectrally-resolved observations of two other transitions at 557 GHz (538 µm…
Mid-infrared spectra of differentiated meteorites (achondrites): Comparison with astronomical observations of dust in protoplanetary and debris disks
Koike, Chiyoe; Mason, Andrew; Morlok, Andreas +4 more
Mid-infrared (5-25 µm) transmission/absorption spectra of differentiated meteorites (achondrites) were measured to permit comparison with astronomical observations of dust in different stages of evolution of young stellar objects. In contrast to primitive chondrites, achondrites underwent heavy metamorphism and/or extensive melting and repre…
