Jupiter's atmospheric composition from the Cassini thermal infrared spectroscopy experiment.
The Composite Infrared Spectrometer observed Jupiter in the thermal infrared during the swing-by of the Cassini spacecraft. Results include the detection of two new stratospheric species, the methyl radical and diacetylene, gaseous species present in the north and south auroral infrared hot spots; determination of the variations with latitude of acetylene and ethane, the latter a tracer of atmo...
متن کاملMid-infrared all-sky survey with AKARI
AKARI (formerly called ASTRO-F) is the first Japanese astronomical infrared satellite and it is now in a sun-synchronous polar orbit at the altitude of 700 km. One of the major programs of AKARI observations is an all-sky survey in the midto far-infrared spectral region with 6 photometric bands. AKARI has a 685mm telescope, which is cooled down to about 6K by superfluid liquid helium and mechan...
متن کاملInfrared spectroscopy of crystalline and amorphous diacetylene (C4H2) and implications for Titan’s atmospheric composition
New laboratory spectra of crystalline and amorphous diacetylene ice have been recorded in the range of 7000–500 cm (1.4–20mm) to aid in the identification of solid diacetylene on Saturn’s moon Titan. We have established that amorphous diacetylene ice is stable only at temperatures less than 7071K. With respect to observations on Titan, the best approach would be to utilize future space-based te...
متن کاملPotential of Near-Infrared Reflectance Spectroscopy (NIRS) to Predict Nutrient Composition of Bromus tomentellus
Determination of forage quality of available species is one of the fundamentalfactors for the management of rangelands. Near-Infrared Reflectance Spectroscopy (NIRS)was used to analysis the Nitrogen (N), Acid Detergent Fiber (ADF), Dry MatterDigestibility (DMD) and Metabolizable Energy (ME) content of three phenological stages(vegetative, flowering and seeding) of Bromus tomentellus samples in ...
متن کاملStudies on the Formation of Mullite from Diphasic Al2O3-SiO2 Gel by Fourier Transform Infrared Spectroscopy
Al2O3-SiO2 diphasic gel was synthesized by sol gel route from aluminium nitrate and silicic acid following aqueous phase colloidal interaction. The precursor gel powder was thoroughly characterized by chemical analysis, measurement of surface area and bulk density measurement. The gel powder was further characterized by thermogravimetry, XRD diffraction stud...
