Information × Registration Number 0115U006893, ( 0221U103336  ) R & D request Title Astrometry of the Solar system small bodies and the ultra-cool dwarfs in the GAIA epoch and compilation of special astrometric catalogues Head Lazorenko Petro F., Кандидат фізико-математичних наук Registration Date 30-12-2015 Organization Main Astronomical Observatory of the National Academy of Sciences of Ukraine popup.description1 High-precision optical astrometry with precision of the measurements better than 1 mas (milliarcsecond) allows one to derive principally new results in such investigations as the Galaxy dynamics, dynamics of stars in the Galaxy center, double stars and exoplanets. However only some telescopes like the Very Large Telescope (VLT) with camera FORS2 allows to obtaine positions with an accuracy of about 0.1 mas. Precise astrometric measuremenets are very important for the detection of components of very cool dwarfs and for improvement of the evolution models of these objects. Photographic observations of more early epochs are necessary elements for the increase of observations in time, thus leads to better coverage of all the orbit by observations. popup.nrat_date 2024-12-10 Close
