DOI: 10.1016/j.icarus.2019.113602
Abstract: Abstract Over the last couple decades, numerous papers based on lightcurve observations of asteroids have derived shapes that were claimed to represent “contact binary” or fluid equilibrium figures. From these shapes, the authors then presumed… read more here.
