Size and density sorting of dust grains in SPH simulations of protoplanetary disc II: Fragmentation
Francesco C. Pignatale, Jean-François Gonzalez, Bernard Bourdon +1
Grain growth and fragmentation are important processes in building up large dust aggregates in protoplanetary discs. Using a 3D two-phase (gas-dust) SPH code, we investigate the co…
Near-Earth Supernova Explosions: Evidence, Implications, and Opportunities
Brian D. Fields, John R. Ellis, Walter R. Binns +36
There is now solid experimental evidence of at least one supernova explosion within 100 pc of Earth within the last few million years, from measurements of the short-lived isotope…
Size and density sorting of dust grains in SPH simulations of protoplanetary discs
Francesco C. Pignatale, Jean-François Gonzalez, Nicolas Cuello +2
The size and density of dust grains determine their response to gas drag in protoplanetary discs. Aerodynamical (size x density) sorting is one of the proposed mechanisms to explai…
Search for supernova-produced 60Fe in a marine sediment
C. Fitoussi, G. M. Raisbeck, K. Knie +8
An 60Fe peak in a deep-sea FeMn crust has been interpreted as due to the signature left by the ejecta of a supernova explosion close to the solar system 2.8 +/- 0.4 Myr ago [Knie e…
