The strength of regolith and rubble pile asteroids [PDF]
, 2013 We explore the hypothesis that, due to small van der Waals forces between constituent grains, small rubble pile asteroids have a small but nonzero cohesive strength.

Inelastic Dissipation in Wobbling Asteroids and Comets [PDF]
, 1998 Asteroids and comets dissipate energy when they rotate about the axis different from the axis of the maximal moment of inertia. We show that the most efficient internal relaxation happens at the double frequency of body's tumbling.

Warme dichte Materie in Natur und Labor: Ein ungewöhnlicher Materiezustand
Physik in unserer Zeit, EarlyView.Warme dichte Materie rückt immer mehr in den Fokus, nicht nur in der Physik und Astronomie, sondern auch in den Ingenieurswissenschaften und sogar der Politik. Es handelt sich um interessante, aber auch komplizierte Zustände von Materie, die unser Verständnis ihrer Funktionsweise herausfordern.

Distribution of spin-axes longitudes and shape elongations of main-belt asteroids
, 2016 Context: Large all-sky surveys provide us with a lot of photometric data that are sparse in time (typically few measurements per night) and can be potentially used for the determination of shapes and rotational states of asteroids.

Asteroid family identification using the Hierarchical Clustering Method and WISE/NEOWISE physical properties [PDF]
, 2013 Using albedos from WISE/NEOWISE to separate distinct albedo groups within the Main Belt asteroids, we apply the Hierarchical Clustering Method to these subpopulations and identify dynamically associated clusters of asteroids. While this survey is limited

Zehn Jahre Gaia‐Messungen: Die hochgenaue Kartierung des Himmels
Physik in unserer Zeit, EarlyView.Das astrometrische Weltraumobservatorium Gaia der Europäischen Weltraumorganisation hat die astrometrische Forschung revolutioniert, indem es unter anderem präzise Positionen, Bewegungen und Entfernungen von fast zwei Milliarden Himmelsobjekten gemessen hat. Damit stellt es wertvolle Daten für fast alle Gebiete der Astrophysik bereit. Nach dem Ende der

BVRI photometry of 53 unusual asteroids
, 2010 We present the results of BVRI photometry and classification of 53 unusual asteroids, including 35 near-Earth asteroids (NEAs), 6 high eccentricity/inclination asteroids, and 12 recently-identified asteroid-pair candidates.

Journal of Field Robotics, EarlyView.ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...

The Brazil nut effect and its application to asteroids [PDF]
, 2014 Out of the handful of asteroids that have been imaged, some have distributions of blocks that are not easily explained. In this paper, we investigate the possibility that seismic shaking leads to the size sorting of particles in asteroids. In particular,
