TL;DR: In this paper , the authors combined multiple datasets of transit photometry and radial velocimetry (RV) to revise the properties of the system and inform models of its planets.

Mitigation of spot elongation effects
Erez N. Ribak,Roberto Ragazzoni +1 more
TL;DR: In this paper, the laser creating the artificial beacon is broken up into many weak independent laser, sent from scattered locations up to the periphery of a large telescope to reduce significantly spot elongation in adaptive optics systems.

TL;DR: In this paper , a consistent part of the services and structures committed to the industry had already been released to the commissioning group, with the exception of the Nasmyth derotators, motors and all the optics groups, basically ready in its mechanical parts to accept the integration of all services and control equipment.
Patent
Telescope, comprising a spherical primary mirror, with wide field of view and high optical resolution
TL;DR: In this article, a spherical primary mirror is replaced by a secondary mirror composed by planar reflective surfaces, which are contiguous one to the other and form a continuous multifaceted prismatic reflector, in such a way as to obtain the continuity of the field of view over the whole field.
Proceedings ArticleDOI
From the most plain coronograph to the most populated spectrograph: a suite of some new instruments for LBT
Demetrio Magrin,Roberto Ragazzoni,Maria Bergomi,A. Brunelli,Marco Dima,Jacopo Farinato,Luca Marafatto,Valentina Viotto +7 more
TL;DR: In this article, a coronagraph is proposed to take advantage of the LBT XAO ability dedicated to the ExoPlanets detection and a multiple very wide field spectrograph is foreseen, all with equal optical elements but for the pupil aberration corrector.
