A New Lightcurve and Spin-Shape Model for 46 Hestia
Abstract
At its opposition in late 2018, minor planet 46 Hestia has a synodic rotation period of 21.039 ± 0.001 h and amplitude 0.11 ± 0.01 mag. A lightcurve inversion model based on four dense data sets in the years 1978- 2018 plus sparse observations provides a sidereal period of 21.04010 ± 0.000035 h with two mirrored pole solutions at longitude 291 deg, latitude +13 deg; or longitude 110 deg, latitude 7 deg; all ± 5 degrees, respectively. A shape model is also provided.
