The ASTRI Mini-Array (MA) is an INAF project to build and operate a facility to study astronomical sources emitting at very high-energy in the TeV spectral band. The ASTRI MA consists of a group of nine innovative Imaging Atmospheric Cherenkov telescopes. The telescopes will be installed at the Teide Astronomical Observatory of the Instituto de

In 2014 TNG also offered GIANO-B to the scientific community, providing a near-infrared (NIR) cross-dispersed echelle spectrograph covering 0.97 − 2.45 µm at a resolution of 50000. The possibility of simultaneously using GIANO-B together with the HARPS-N spectrograph (GIARPS observing mode) has been particularly appealing especially for the search

We present the discovery of TOI-2136 b, a sub-Neptune planet transiting a nearby M4.5V-type star every 7.85 d, identified through photometric measurements from the Transiting Exoplanet Survey Satellite (TESS) mission. The host star is located 33 pc away with a radius of R * = 0.34 ± 0.02 R ⊙, a mass of $0.34\pm 0.02 \, \mathrm{M}_{\odot }$, and an

We complete the analysis of all 2018 prime-field microlensing planets identified by the Korea Microlensing Telescope Network (KMTNet) Anomaly Finder. Among the ten previously unpublished events with clear planetary solutions, eight are either unambiguously planetary or are very likely to be planetary in nature: OGLE-2018-BLG-1126, KMT-2018-BLG-2004

This contribution describes the software and electronic improvements implemented in the GREGOR Infrared Spectrograph (GRIS) installed on the Gregor telescope. It is located at the Teide Observatory, in Tenerife, Islas Canarias, Spain. As a demonstrator for an instrument for the European Solar Telescope (EST), this project aims to perform

This contribution presents the structural analysis that followed the preliminary design specifications of the European Solar Telescope (EST). EST is a 4-metre class telescope based on an aplanatic Gregorian configuration with an alt-azimuthal mount. The optical design has undergone several changes since the end of the conceptual phase. A finite
