A Multiscale Investigation of the Physical Origins of Tension--Compression Asymmetry in Crystals and their Implications for Cyclic Behavior
Sylvain Queyreau, Benoit Devincre
Most of crystalline materials develop an hysteresis on their deformation curve when a mechanical loading is applied in alternating directions. This effect, also known as the Bausch…
Contemporary formation of early solar system planetesimals at two distinct radial locations
Alessandro Morbidelli, Kevin Baillie, Konstantin Batygin +4
The formation of planetesimals is expected to occur via particle-gas instabilities that concentrate dust into self-gravitating clumps. Triggering these instabilities requires the p…
OGLE-2014-BLG-0319: A Sub-Jupiter-Mass Planetary Event Encountered Degeneracy with Different Mass Ratios and Lens-Source Relative Proper Motions
Shota Miyazaki, Daisuke Suzuki, Andrzej Udalski +36
We report the discovery of a sub-Jovian-mass planet, OGLE-2014-BLG-0319Lb. The characteristics of this planet will be added into a future extended statistical analysis of the Micro…
The Physical Properties of the SVS 13 Protobinary System: Two Circumstellar Disks and a Spiraling Circumbinary Disk in the Making
Ana K. Diaz-Rodriguez, Guillem Anglada, Guillermo Blázquez-Calero +13
We present VLA and ALMA observations of the close (0.3" = 90 au separation) protobinary system SVS 13. We detect two small circumstellar disks (radii 12 and 9 au in dus…
Resurfacing processes constrained by crater distribution on Ryugu
Naofumi Takaki, Yuichiro Cho, Tomokatsu Morota +16
Understanding the geological modification processes on asteroids can provide information concerning their surface history. Images of small asteroids from spacecraft show a depletio…
Ellipsoidal equilibrium figure and Cassini states of rotating planets and satellites deformed by a tidal potential in the spatial case
Hugo A. Folonier, Gwenaël Boué, Sylvio Ferraz-Mello
The equilibrium figure of an inviscid tidally deformed body is the starting point for the construction of many tidal theories such as Darwinian tidal theories or the hydrodynamical…
