Extending the Asteroseismic Calibration of the Stellar Rossby Number
Travis S. Metcalfe, Enrico Corsaro, Alfio Bonanno +2
The stellar Rossby number (Ro) is a dimensionless quantity that is used in the description of fluid flows. It characterizes the relative importance of Coriolis forces on convective…
