The Antarctic Plateau Interferometer (API) is an instrument concept capable of extensive unique discovery space science in a variety of areas including exoplanets, accretion, YSO's, and AGNs. To study exoplanets in the habitable zone, API would use three 2 meter class telescopes…
Abstract. Due to the typical high atmospheric noise and low opacity, submillimeter observations … can be carried out only from sites with very high atmospheric stability and very … low precipitable water vapour content.
Ground layer Adaptive Optics (GLAO) is a new variant of adaptive optics that aims at correcting the seeing … over a wide field of view by conjugating the deformable mirror to the boundary layer altitude.
The Antarctic Fibre-Optic Spectrometer (AFOS) is a 30cm Newtonian optical telescope that injects light through … six 30m long optical ¯bres onto a 240¡850nm spectrograph with a 1024 x 256 pixel CCD camera.
To properly characterize the atmospheric properties of a site for a future large telescope or interferometer, it is insufficient to … measure quantities, such as the full-width at half-maximum of a stellar image, that have been integrated over the entire … atmosphere.
The perfect site for astronomical interferometry would be one where the wind speeds throughout the atmosphere were … very low, there was little atmospheric turbulence (especially at high altitudes), the seismic activity was negligible and … the climate very stable. Perhaps surprisingly…
The primary limitation to ground based astronomy is the Earth's atmosphere. The atmosphere above the … Antarctic plateau is fundamentally dierent in many regards compared to the atmosphere at temperate sites. The … extreme altitude…
