Resum
Being the first of its kind, the white dwarf WD 1145+017 exhibits a complex system of disintegrating debris which offers a unique opportunity to study its disruption process in real time. Even with plenty of transit observations there are no clear constraints on the masses or eccentricities of such debris. Using N-body simulations, we show that masses greater than ¿1020 kg (a tenth of the mass of Ceres) or orbits that are not nearly circular (eccentricity > 10-3) dramatically increase the chanc...
