First scattered-light images of the gas-rich debris disk around 49 Ceti
É. Choquet, J. Milli, Z. Wahhaj +31
We present the first scattered-light images of the debris disk around 49 ceti, a ~40 Myr A1 main sequence star at 59 pc, famous for hosting two massive dust belts as well as large…
Nanoindenting the Chelyabinsk meteorite to learn about impact deflection effects in asteroids
Carles E. Moyano-Cambero, Eva Pellicer, Josep M. Trigo-Rodríguez +7
The Chelyabinsk meteorite is a highly shocked, low porosity, ordinary chondrite, probably similar to S- or Q-type asteroids. Therefore, nanoindentation experiments on this meteorit…
ALMA Observations of the Water Fountain Pre-Planetary Nebula IRAS 16342-3814: High-velocity bipolar jets and an Expanding Torus
R. Sahai, W. H. T. Vlemmings, T. Gledhill +4
We have mapped 12CO J=3-2 and other molecular lines from the "water-fountain" bipolar pre-planetary nebula (PPN) IRAS 16342-3814 with ~0."35 resolution using ALMA. We find (i) two…
Survival of the impactor during hypervelocity collisions II: An analogue for high porosity targets
Chrysa Avdellidou, Mark C. Price, Marco Delbo +1
We investigated how a target's porosity affects the outcome of a collision, with respect to the impactor's fate. Laboratory impact experiments using peridot projectiles were perfor…
Observation of mode-locked spatial laser solitons
F. Gustave, N. Radwell, C. McIntyre +6
A stable nonlinear wave packet, self-localized in all three dimensions, is an intriguing and much sought after object in nonlinear science in general and in nonlinear photonics in…
Highly inclined and eccentric massive planets. II. Planet-planet interactions during the disc phase
Sotiris Sotiriadis, Anne-Sophie Libert, Bertram Bitsch +1
We aim to investigate the influence of the eccentricity and inclination damping due to planet-disc interactions on the final configurations of the systems, generalizing previous st…
