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 ...

Near infrared surface photometry of late-type Virgo cluster galaxies
Astronomy and Astrophysics, 1997 Near Infrared ($K^{\prime}$ band) surface photometry has been obtained for 102 (88 late-type) Virgo cluster galaxies. A subset of 20 galaxies was also imaged in the H band.

Infrared Photometry of Solar Active Regions
International Astronomical Union Colloquium, 2000AbstractSimultaneous time series of broad-band images of two active regions close to the disk center were acquired at the maximum (0.80μm) and minimum (1.55μm) continuum opacities. Dark faculae are detected in images obtained as weighted intensity differences between both wavelength bands. The elements of quiet regions can be clearly distinguished from

Infrared photometry of S stars
Astrophysics, 1981Results are given of observations of 13 S stars in Stephenson's catalog (1976) in the range 0.98-2.39 microns. Observations were made with a 2.6-m reflecting telescope using a PbS detector cooled by carbon dioxide. An infrared excess at 1.75 microns is found for some of the stars, and absorption at 2.39 microns is found for all of them.

Near-Infrared photometry of Neptune’s small regular satellites with Keck
IcarusInternational audienceWe present data and images that provide insight on the infrared photometry and reflectivity of five of Neptune's small, regular moons: Proteus, Despina, Galatea, Larissa, and Naiad. Data were taken in the H-band (1.485- 1 .

Photometry with Infrared Arrays
International Astronomical Union Colloquium, 1993AbstractInfrared arrays have been in use at a number of observatories for several years. They are more complicated in their construction than optical ones and more problems arise in obtaining good photometry from them. The types of arrays currently available are described together with the observational techniques and the problems encountered in ...

Analysis of infrared photometry of algol
Astrophysics and Space Science, 1984Infrared (JHKLM) photometry of β Per, due to Zeilik (1980), has been analysed by computer-based optimization methods. The data have been used primarily to find empirical mean flux ratios at known IR wavelengths for the two photospheres of the eclipsing pair.

Infrared photometry of Comet Kohoutek
Icarus, 1974Abstract Before perihelion, the 8.8–21 μm luminosity of Comet Kahoutek (1973f) was on the order of 1021 ergsec−1 and dropped to 1020 ergsec−1 after perihelion.

Infrared photographic photometry with an ‘instant’ film
Journal of Audiovisual Media in Medicine, 1982The use of infrared-sensitive film for making measurements of the infrared reflectance of pigmented lesions has been described previously (Marshall, 1976, 1980, 1981). The present paper describes the use of an experimental ‘instant’ infrared film produced and made available by the Polaroid Corporation.
