| Zusammenfassung |
| In this paper, we discuss scintillation time-spectra of the double star
α Cru, which were measured by the GOMOS/Envisat photometer. The components of
α Cru are not resolved by the angular field of view of the detector. The
double structure of the light source reveals itself in the modulation of the
observed scintillation spectra; this modulation is caused by anisotropic
irregularities of the stratospheric air density. We present a qualitative
and quantitative explanation of the properties of the double-star
scintillation spectra. Possibilities of using double star scintillations for
studying atmospheric air density irregularities are also discussed in the
paper. |
