Abstract

Nowadays, majority of space missions (e.g. ESA PLATO, NASA TESS and JWST) are focusing their telescopes to the nearby bright stars. However, only up to 30% of necessary information from high-resolution spectroscopy, like the main atmospheric parameters and detailed chemical composition, is available even for the brightest targets. This opens a new era for small ground-based telescopes like 1 m SONG in Canary Islands or 1.65 m Moletai Astronomical Observatory (MAO) telescope in Lithuania. Since 2016, we are conducting spectroscopic observations with the high-resolution VUES spectrograph (400 – 880 nm; R = 60 000) that is installed on the MAO 1.65 m telescope. About five hundreds stars up to V= 8 mag were already observed in several fields of the northern hemisphere and the first results of the analysis are presented in this contribution. A synergy of observations with the SONG and 1.65MAO telescopes is discussed.
