We observe a progression of emission features in the 8–11 μm region in MS, S and SC stars that parallels their increasing C:O ratio and s-process enhancements.

We observed the 22.2 GHz H2O maser line from the two C stars EU And and V778 Cyg. The intensity of the line has varied by more than a factor of 5 over several month and the line has shown additional weaker components. We interpret the system as being

The Infrared Astronomical Satellite (IRAS) carried a low resolution spectrometer (LRS) with a wavelength response covering the 8 to 22 micrometer region. About 5000 LRS spectra exist of point sources brighter than 10 Jy at 12 and 25 micrometers. Spec

A total of 291 M Mira variables with IRAS low-resolution spectrometer (LRS) spectra that have 8-micron fluxes greater than 15 Jy have been analyzed. After subtraction of a 2500 K blackbody energy distribution from the spectrum, the remaining differen

By comparing IRAS mean colors and LRS spectral differences in a large sample of Mira variables with the chronological sequence for development of microwave maser emission among such stars, it appears possible to describe a dust grain formation and an

Recent high-resolution spectra of Mars have confirmed the existence of water vapor in the atmosphere of that planet. New laboratory measurements and improved temperature corrections have resulted in more accurate abundances than previously. In Februa

Water vapor was found to reappear in the atmosphere of Mars during its southern hemisphere spring and summer season, with a maximum vertical column abundance of 45 to 50 microns of precipitable water averaged over the entire planet. Although the spri

The results of a survey of 279 late-type giants and supergiants for the spectral lines of the radioactive element technetium (Tc I) at 4297, 4262, and 4238 A are presented. The following conclusions are reached: (1) the presence of Tc correlates very

The H-II region W51 has been mapped in the near-infrared H and K wavebands with a resolution of about 6 arcsec over an area of about 14 sq arcsec. The W51 IRS 1 source has been resolved into six components, and an arc-like extension of small H-II reg
