A large topographic feature on the surface of the trans-Neptunian object (307261) 2002 MS measured from stellar occultations

F. L. Rommel, F. Braga-Ribas, J. L. Ortiz +201

This work aims at constraining the size, shape, and geometric albedo of the dwarf planet candidate 2002 MS4 through the analysis of nine stellar occultation events. Using multichor…

The size, shape, density and ring of the dwarf planet Haumea from a stellar occultation

J. L. Ortiz, P. Santos-Sanz, B. Sicardy +90

Among the four known transneptunian dwarf planets, Haumea is an exotic, very elongated, and fast rotating body. In contrast to the other dwarf planets, its size, shape, albedo, and…

Activity of (2060) Chiron possibly caused by impacts?

Stefan Cikota, Estela Fernández-Valenzuela, Jose Luis Ortiz +5

The centaur 95P/(2060) Chiron is showing comet-like activity since its discovery, but the mass-loss mechanisms triggering its activity remained unexplained. Although the collision…

Photometric survey, modelling, and scaling of long-period and low-amplitude asteroids

A. Marciniak, P. Bartczak, T. Müller +40

The available set of spin and shape modelled asteroids is strongly biased against slowly rotating targets and those with low lightcurve amplitudes. As a consequence of these select…

A photometric search for active Main Belt asteroids

S. Cikota, J. L. Ortiz, A. Cikota +2

It is well known that some Main Belt asteroids show comet-like features. A representative example is the first known Main Belt comet 133P/(7968) Elst-Pizarro. If the mechanisms cau…
