Infrared stars or infrareddened stars?
Nature, 1974Extreme interstellar reddening, accompanying visual absorption of order 100 magnitudes, is still a viable explanation for infrared objects like Becklin's star in spite of recent claims to the contrary. It is unnecessary at this stage to invoke a new phase of protostellar evolution to account for them.

Infrared Velocities of Carbon Stars
Astrophysics and Space Science, 1994We have measured radial velocities of infrared photospheric lines observed in 37 bright carbon stars. The spectra were obtained on the Kitt Peak National Observatory 4 meter telescope with Fourier transform spectrometers between 1976 and 1988. The observations have a typical resolution of 65000 and a typical signal-to-noise ratio of 50. All the spectra

Infrared photometry of AGB stars
Astrophysics and Space Science, 1994The goal of this article is to show that, if one avoids star forming regions, mass-losing AGB stars can generally be selected from the data that will be provided by the near-infrared surveys which are presently considered. Also, if IRAS data are available, the separation between carbon-rich and oxygen-rich stars can be operated by their positions in ...

Carbon stars in infrared surveys
Astrophysics and Space Science, 1994In order to prepare the analysis of the forthcoming near-IR surveys (DENIS, 2MASS) and to interpret them in terms of galactic structure and AGB evolution, we present model predictions of AGB distributions in K, in 12µm and in (J-K, [12–25]) space, as they will be obtained from these surveys, cross-correlated with IRAS Catalog. The simulations have been

Infrared Spectroscopy of Stars
Annual Review of Astronomy and Astrophysics, 1979This paper reviews applications of IR techniques in stellar classification, studies of stellar photospheres, elemental and isotopic abundances, and the nature of remnant and ejected matter in near-circumstellar regions. Qualitative IR spectral classification of cool and hot stars is discussed, along with IR spectra of peculiar composite star systems ...

Annual Review of Astronomy and Astrophysics, 1969
This review of infr·ared spectroscopy will be restricted to stars, and to wavelengths longer than 9000 A (0.9 p.). Infrared studies of the Sun will not be considered for their own sake but will frequently be called upon to help interpret the spectra of other stars. Infrared stellar photometry will be discussed only when it can be used to study spectral

Applied Optics, 1986
A computer-controlled star tracker has been built for use in the IR. A small dedicated computer is the active element in a servo loop that moves two small mirrors located in the light path and keeps the light beam centered in the input aperture of an IR heterodyne spectrometer.
