Simulation data for the article "Revisiting a disky origin for the faint branch of the Sagittarius stellar stream"

Description

This archive contains the data shared in the context of the "Revisiting a disky origin for the faint branch of the Sagittarius stellar stream" (Oria et al. 2022) article. It allows one to run the simulation of the Sgr dwarf falling into the joint potential of the MW and the LMC, based on the model of Vasiliev et al. (2021), and extended with our faint branch particles. Furthermore, plots and videos complementary to those shown in the article are shared here as well.

best_model_y_axis_rotation

contains data pertaining to our best model, put forward in the article: plots of the evolution of our faint branch particles for every snapshot of the simulation and its corresponding video, initial conditions, trajectory of the progenitor, final snapshot with many coordinates and kinematics. 

other_model_x_axis_rotation

contains the same data as before for our other model mentioned in the article

potentials_triax

contains the evolving MW+LMC potential files as shared by Vasiliev et al. (2021), under DOI 10.5281/zenodo.4300977 necessary to run the simulation

scripts

contains scripts to create the initial conditions (with Agama) and run the simulation (with Gyrfalcon)
