Atmospheric scintillation noise in ground-based exoplanet photometry

Autor: Richard Wilson, D. Föhring, V. S. Dhillon, James Osborn

Publikováno v: Monthly notices of the Royal Astronomical Society, 2019, Vol.489(4), pp.5098-5108 [Peer Reviewed Journal]

Atmospheric scintillation caused by optical turbulence in the Earth's atmosphere can be the dominant source of noise in ground-based photometric observations of bright targets, which is a particular concern for ground-based exoplanet transit photomet

`Imaka is a ground layer adaptive optics (GLAO) demonstrator on the University of Hawaii 2.2m telescope with a 24'x18' field-of-view, nearly an order of magnitude larger than previous AO instruments. In 15 nights of observing with natural guide star

We report follow-up observations of 477 program Near-Earth Asteroids (NEAs) using nine telescopes of the EURONEAR network having apertures between 0.3 and 4.2 m. Adding these NEAs to our previous results we now count 739 program NEAs followed-up by t
