Constraining surface properties of asteroid (162173) Ryugu from numerical simulations of Hayabusa2 mission impact experiment
Martin Jutzi, Sabina D. Raducan, Yun Zhang +2
The Hayabusa2 mission impact experiment on asteroid Ryugu created an unexpectedly large crater. The associated regime of low-gravity, low-strength cratering remained largely unexpl…
A very luminous jet from the disruption of a star by a massive black hole
Igor Andreoni, Michael W. Coughlin, Daniel A. Perley +78
Tidal disruption events (TDEs) are bursts of electromagnetic energy released when supermassive black holes (SMBHs) at the centers of galaxies violently disrupt a star that passes t…
Spectral analysis of basaltic asteroids observed by the Gaia space mission
Dagmara Oszkiewicz, Hanna Klimczak, Benoit Carry +4
There is a great deal of scientific interest in characterizing the basaltic asteroids (spectrally classified as V-types), as they are the key to understanding planetesimal formatio…
Discontinuous Shear Thickening (DST) transition with spherical iron particles coated by adsorbed brush polymer
Georges Bossis, Yan Grasselli, Olga Volkova
In this work we explore the rheology of very concentrated (0.55<<0.67) suspensions of carbonyl iron (CI) particles coated by a small polymer. A strong DST is observed in a large…
Deep scene-scale material estimation from multi-view indoor captures
Siddhant Prakash, Gilles Rainer, Adrien Bousseau +1
The movie and video game industries have adopted photogrammetry as a way to create digital 3D assets from multiple photographs of a real-world scene. But photogrammetry algorithms…
The crater-induced YORP effect
Wen-Han Zhou, Yun Zhang, Xiaoran Yan +1
The Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect plays an important role in the rotational properties and evolution of asteroids. While the YORP effect induced by the macros…
