Notes. The table shows data for 14 different simulations for the initial 2 M⊙ RG model. The columns display a model letter, the equation of state, the reconstruction method (cf. Sect. 3.3), the grid type (HP – HEALPix, CU – cubic, CA – cubic adaptive, CN – cubic nested; cf. Sect. 2.1), the core cutoff radius rc as a fraction of the initial model radius, the number of cells N, the radius and gas mass of the reconstructed profile in solar units, the mean Mach number at the end of the relaxation run and the mean relative difference in the hydrostatic equilibrium. The mean values are computed using the cell mass as weight. The core mass in all simulations is 0.38 M⊙.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
