| Abstract |
Our Sun rotated much more rapidly when it was younger, as is suggested
by observations of rapidly rotating solar-like stars and the influence
of the solar wind, which removes angular momentum from the Sun. By
studying how flux emergence may have occurred on the young Sun, we are
likely to learn more about the nature of the solar dynamo early in the
Sun's history, as well as other solar-like stars. To investigate this,
we embed a toroidal flux tube near the base of the convection zone of a
rotating spherical shell of turbulent convection performed for
solar-like stars that rotate 3, 5, and 10 times the current solar rate.
Our objective is to understand how the convective flows of these fast
rotators can influence the emergent properties of flux tubes which would
rise to create active regions, or starspots, of a variety of magnetic
flux strengths, magnetic fields, and initial latitudes. Flux tube
properties we will discuss include rise times, latitude of emergence,
and tilt angles of the emerging flux tube limbs with respect to the
east-west direction. Also of interest is identifying the regimes where
dynamics of the flux tube are convection dominated or magnetic buoyancy
dominated, as well as attempting to identify active longitudes. |
