Reconstruction of asteroid spin states from Gaia DR2 photometry

Asteroid Models from the Pan-STARRS Photometry

We present simulations on the asteroid photometric data that will be provided by the PanSTARRS (Panoramic Survey Telescope and Rapid Response System). The simulations were performed using realistic shape and light-scattering models, random orientation of spin axes, and rotation periods in the range 2–24 h. We show that physical models of asteroids can be reconstructed from this data with some l...

Asteroid occultations today and tomorrow: toward the GAIA era

Context. Observation of star occultations is a powerful tool to determine shapes and sizes of asteroids. This is key information necessary for studying the evolution of the asteroid belt and to calibrate indirect methods of size determination, such as the models used to analyze thermal infrared observations. Up to now, the observation of asteroid occultations is an activity essentially secured ...

Photometric properties of theoretical spectral libraries for GAIA photometry

Photometric properties of various spectral libraries of synthetic stellar spectra derived from the ATLAS 9 (Castelli et al. 1997), the PHOENIX NextGen (Hauschildt et al. 1998, 1999), the NMARCS (Bessell et al. 1998), and the BaSeL (Lejeune et al. 1998, Westera et al. 2002) models are discussed in view of their application to the definition of the GAIA photometric system. Comparisons with empiri...
