  author={Andrei M. Beloborodov and Yuri Levin},
The traditional way of estimating the gravitational field from observed motions of test objects is based on the virial relation between their kinetic and potential energy. We find a more efficient method. It is based on the natural presumption that the objects are observed at a random moment of time and therefore have random orbital time phases. The proposed estimator, which we call “orbital roulette”, checks the randomness of the phases. The method has the following advantages: (1) It… CONTINUE READING
