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 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.
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 کاملAngular Brushing of Extended Parallel Coordinates
In this paper we present angular brushing for parallel coordinates (PC) as a new approach to highlighting rational data-properties, i.e., features which – in a non-separable way – depend on two data dimensions. We also demonstrate smooth brushing as an intuitive tool for specifying nonbinary degree-of-interest functions (for focus+context visualization). We also briefly describe our implementat...
متن کاملMicrolensing of Extended Stellar Sources
We investigate the feasibility of reconstructing the radial intensity profile of extended stellar sources by inverting their microlensed light curves. Using a simple, linear, limb darkening law as an illustration, we show that the intensity profile can be accurately determined, at least over the outer part of the stellar disc, with realistic light curve sampling and photometric errors. The prin...
