Stability Constrained Characterization of the 23 Myr-old V1298 Tau System: Do Young Planets Form in Mean Motion Resonance Chains?
Roberto Tejada Arevalo, Daniel Tamayo, Miles Cranmer
A leading theoretical expectation for the final stages of planet formation is that disk migration should naturally drive orbits into chains of mean motion resonances (MMRs). In ord…
Collisional regime during the discharge of a 2D silo
Roberto Arévalo
The present work reports a novel investigation into the collisional dynamics of particles in the vicinity of the outlet of a 2D silo using molecular dynamics simulations. Most stud…
A topological method to characterize tapped granular media from the position of the particles
Sergio Ardanza-Trevijano, Iker Zuriguel, Roberto Arevalo +1
We use the first Betti number of a complex to characterize the morphological structure of granular samples in mechanical equilibrium. We analyze two-dimensional granular packings a…
Size and density avalanche scaling near jamming
Roberto Arévalo, Massimo Pica Ciamarra
The current microscopic picture of plasticity in amorphous materials assumes local failure events to produce displacement fields complying with linear elasticity. Indeed, the flow…
Topological properties of the contact network of granular packings
Roberto Arevalo, Iker Zuriguel, Diego Maza
The force networks of different granular ensembles are defined and their topological properties studied using the tools of complex networks. In particular, for each set of grains c…
The flow rate of granular materials through an orifice
C. Mankoc, A. Janda, R. Arévalo +4
The flow rate of grains through large orifices is known to be dependent on its diameter to a 5/2 power law. This relationship has been checked for big outlet sizes, whereas an empi…
