    Invited talk

    The Gaia third data release (DR3) includes the mean reflectance spectra of 60 518 asteroids at visible wavelengths (0.374–1.05 μm), which is a 10-fold increase in the number of known asteroid spectra (Galluccio et al. 2022). This huge increase in the number of available asteroid spectra provides more detailed distributions of various taxonomies across the Solar System and thus expands our...

  3. 42. Estimating the Shapes and Spins of Asteroids from GAIA DR3 Photometry (online)

    Contributed talk

    Photometric inversion is a technique that has been used for several decades to infer the shape and spin properties of asteroids [1]. Inversion methods have extensively been applied to ground- based observations of asteroids [2], but the high- precision data provided by the Gaia mission has enabled more detailed studies of these objects.
    Previous data releases have demonstrated the usefulness...

  4. 85. The Photocenter-Barycenter Effect in Gaia astrometry and its Impact on Asteroid Orbit Determination (online)
    Karolina Dziadura (Adam Mickiewicz University in Poznan)

    Contributed talk

    The recent advancement of observational capabilities, particularly with the addition of Gaia observations, has brought significant improvements in the determination of orbital parameters for Small Solar System bodies. In this study, we investigate the impact of incorporating Gaia Data Release 3 (DR3) into the orbit determination process, with a specific focus on the photocenter-barycenter...

  5. 94. Shape modelling and spectral classification of asteroids using data from the AS Vidojevica and Gaia DR3
    Gordana Apostolovska (Institute of Physics, Faculty of Natural Sciences and Mathematics, Ss. Cyril and Methodius University in Skopje)

    Contributed talk

    We present the physical models of asteroids, their shapes, sense of
    rotation, and spectral classes using Gaia DR3. The shape models were
    determined using the lightcurve inversion method with the combination of
    dense photometric data from the Astronomical Station Vidojevica in
    Serbia and sparse data from the Gaia mission.

    For obtaining asteroid low-resolution shapes, using sparse...

  6. 95. GAIA mission: the true time saver for asteroids shape modeling and spectral classification
    Elena Vchkova Bebekovska (Institute of Physics, Faculty of Natural Sciences and Mathematics, Ss. Cyril and Methodius, University in Skopje)

    Contributed talk

    Our work aims to determine the shape models of a few asteroids, derived by using a combination of our dense photometric data with the sparse data provided by the database AstDys and as well as by the GAIA mission. These sparse data help us in gaining additional information for the asteroids with a small number of lightcurves and are in favor of the required observational time. Unlike the...
