Spin-Shape Model for 33 Polyhymnia - NASA/ADS
We present a shape and spin axis model for main-belt asteroid 33 Polyhymnia. The model was achieved with the lightcurve inversion process, using combined dense photometric data acquired from five apparitions, between 2008-2019 and sparse data from USNO Flagstaff.
