  • We present the first attempt to fit the light curve of the interstellar visitor `Oumuamua using a physical model which includes optional torque. We consider both conventional (Lommel-Seeliger triaxial ellipsoid) and alternative ("black-and-white ball", "solar sail") brightness models. With all the brightness models, some torque is required to explain the timings of the most conspicuous features -- deep minima -- of the asteroid's light curve. Our best-fitting models are a thin disc (aspect… CONTINUE READING
