TL;DR: In this paper , the authors measured the occultation depth in the broad optical bandpass of CHEOPS (350 - 1100 nm) to infer the geometric albedo of the gas giant HD 189733b.
Proceedings ArticleDOI
Novel techniques concerning MCAO: trying to overcome fundamental limitations
TL;DR: In this article, the authors propose to use the superimposition of the light coming from several references at the level of the detector in order to increase the SNR and is using just the signal which is needed to drive loops indipendently tuned to different altitudes.
Proceedings ArticleDOI

TL;DR: In this paper, a mission into hot phenomena in the universe is proposed by means of a small telescope of 50 cm aperture accommodated on the International Space Station (ISS), which will use a pointing platform attached to an Express Pallet Adapter available to the Italian Space Agency (ASI) more than 4 - 6 months per year.
Journal ArticleDOI
Operation of a layer-oriented multiconjugate adaptive optics system in the partial illumination regime
Kalyan Kumar Radhakrishnan Santhakumari,Kalyan Kumar Radhakrishnan Santhakumari,Carmelo Arcidiacono,Thomas Bertram,Florian Briegel,Tom Herbst,Roberto Ragazzoni +6 more
TL;DR: In this paper, the authors report a working solution to this difficulty for layer-oriented MCAO, including laboratory and on-sky demonstration with the LINC-NIRVANA instrument at the Large Binocular Telescope.

TL;DR: MEMORIS (MErcury Moderate Resolution Imaging System) is a wide angle camera (WAC) concept for the ESA mission BepiColombo as mentioned in this paper, which will obtain a map of Mercury in stereo mode allowing the determination of a digital elevation model with a panchromatic filter through two different channels.
