Large surveys are invaluable sources of asteroid photometry. If there are enough data points with sufficient photometric accuracy, this sparse-in-time photometry can be used for asteroid shape and spin-state reconstruction with the light curve inversion method 1, 2.We will present our results obtained by processing asteroid photometry from Gaia DR3 3 and ATLAS 4. We have derived convex shape models and spin states for about 15,000 asteroids. The distribution of asteroid spins across the main belt and in asteroid families is size-dependent and clearly shows that the rotation axes of asteroids are affected by the thermal YORP effect, which then affects the semimajor drift due to the Yarkovsky effect.Acknowledgments: This work was supported by the grant 23-04946S of the Czech Science Foundation.References: 1 Kaasalainen et al.
