Snapshots

'70' snapshot datafile download

Select the datafiles you wish to export from this snapshot (a zip file containing the requested datafiles will be prepared) :

70 (t=$5.93394$)

Snapshot at 5.93 ORPs.

Notations:

$r_d$ : radius of the disk
ORP : outer rotation period, that is period of the gas at $r_d$
$M_\star$ : Mass of the central object
$v_{k,d}$ : Keplerian speed at $r_d$

All slices are taken at $z=0$ or $y=0$.
