Comet Hale-Bopp was observed five times with ISOPHOT, the photometer on board ESA's Infrared Space Observatory (ISO) between 4.6 and 2.8 AU. Each time, broadband photometry was performed using 4 different detectors, 5 apertures and 10 filters coverin

Present evidence for where and in what forms the abundant elements O, C, N, Si, Mg, Fe, and S occur in molecular clouds is reviewed. Studies of both gas and dust show that most of the elements, with the probable exception of N, are far below cosmic a

Searches for the R(O) line of the CH4v3 band at 3.3 μm give CH4/CO ≤3.3 x 10−2 in AFGL 961 (Rosette Nebula) and ≤2.4 x 10−3 in AFGL 989 (NGC 2264). The results are consistent with ion-molecule models, but the observations may not sample regi

We have measured the spectrum of Titan near 5 micrometers and have found it to be dominated by absorption from the carbon monoxide 1-0 vibration-rotation band. The position of the band edge allows us to constrain the abundance of CO in the atmosphere

Next Generation Infrared Space Observatory ISBN: 9789401051866
EDISON, a large-aperture, radiatively-cooled telescope, is proposed as the major international mission to follow the current generation of cryogenically-cooled infrared space telescopes. It is being studied at present as a 2.5–3.5 m mixed radiative

A broad 10-micron emission feature has been detected within 3 arcsec of the star Beta Pic which is known to have a circumstellar, possibly protoplanetary, disk. The observations were made using four narrow-band filters in the MSFC bolometer array at

The 3.4 micron emission feature due to cometary organics was detected in Comets P/Brorsen-Metcalf and Okazaki-Levy-Rudenko (1989r). Features-to-continuum ratios in these two comets were higher than those expected from the trend seen in other comets t

Infrared spectra (7–40 μ) of the carbonaceous chondrites, Cold Bokkeveld, Murray, and Orgueil are compared with phyllosilicate minerals and interstellar grain spectra. Similarities in the position and shape of the silicate feature near 9.8 μ sugg
