Infrared high angular resolution measurements of stellar sources III. Angular diameters and effective temperatures of eleven late-type giants
Near-infrared lunar occultation observations of eleven late-type giants in the spectral range K0 to M6 (including one carbon star) are reported here. These stars are resolved fromour observations carried out at 2.2μm, resulting in accurate determinations of their angular sizes, with values in the range 1.4 to 7.1 milliseconds of arc (mas) and a typical accuracy of 0.12 mas. Nine out of eleven s...
متن کاملInfrared high angular resolution measurements of stellar sources IV. Angular diameters and effective temperatures of fifteen late-type stars
We have measured the angular diameter of fifteen late-type stars in the near-infrared using the technique of lunar occultations. Included are ten giant stars in the spectral range K0–M10, three M supergiants and two carbon stars. The resulting uniform-disk angular diameters are in the range 2.5 to 10.0 milliseconds of arc (mas), and the average formal error is 0.17 mas. In one case where the sa...
متن کاملAutonomous Lunar Orbit Determination using Star Occultation Measurements
A method has been developed for performing autonomous Lunar orbit determination based on measurements of the times at which stars set behind or rise above the Lunar limb. This system is being developed as a possible technology for use in the Lunar exploration initiative because it enables increased autonomy of operations near the Moon. The system consists of a specially modified star camera and...
متن کاملUv Stellar Occultation Measurements of Nighttime Equatorial Ozone
The Princeton University Ultraviolet Spectrometer-Telescope on the NASA Orbiting Astronomical Observatory Copernicus was used for stellar occultation measurements of atmospheric ozone. Two sets of observations of the target star 8-Cen were carried out on 26 July 1975 and 13-14 June 1976 at wavelengths from 2550• to 3100•. After unfolding of the data, ozone density profiles near the equator with...
متن کاملMean Angular Diameters and Angular Diameter Amplitudes of Bright Cepheids
We predict mean angular diameters and amplitudes of angular diameter variations for all monoperiodic Population I Cepheids brighter than 〈V 〉 = 8.0 mag. The catalog is intended to aid selecting most promising Cepheid targets for future interferometric observations.
