Microporosity and parent body of the rubble-pile NEA (162173) Ryugu
Wladimir Neumann, Matthias Grott, Mario Trieloff +4
Observations of C-type NEAs and lab investigations of carbonaceous chondritic (CC) meteorites provide strong evidence for a high porosity of C-type asteroids. Boulder microporosity…
The specific heat of astro-materials: Review of theoretical concepts, materials and techniques
Jens Biele, Matthias Grott, Michael E. Zolensky +2
We provide detailed background, theoretical and practical, on the specific heat cp of minerals and mixtures thereof, 'astro-materials', as well as background information on common…
On the stability of spinning asteroids
B. N. J. Persson, J. Biele
Most asteroids with a diameter larger than are rubble piles i.e. consisting of more than one solid object. All asteroids are rotating but almost all asteroids…
Asteroid Ryugu Before the Hayabusa2 Encounter
Koji Wada, Matthias Grott, Patrick Michel +31
Asteroid (162173) Ryugu is the target object of Hayabusa2, an asteroid exploration and sample return mission led by Japan Aerospace Exploration Agency (JAXA). Ground-based observat…
Experimental Determination of the Structural Coefficient of Restitution of a Bouncing Asteroid Lander
Jens Biele, Lars Kesseler, Christian D. Grimm +4
The structural coefficient of restitution describes the kinetic energy dissipation upon low-velocity (~0.1 m/s) impact of a small asteroid lander, MASCOT, against a hard, ideally e…
