Does the Babcock-Leighton dynamo operate in rapidly rotating solar-type stars? Exploration using a 3D dynamo model at different rotation rates
Vindya Vashishth, Bidya Binay Karak
The Babcock-Leighton dynamo, which relies on the generation of a poloidal field through the decay and dispersal of tilted bipolar magnetic regions (BMRs), is a promising paradigm f…

The role of meridional flow in the generation of solar/stellar magnetic fields and cycles
Vindya Vashishth, Bidya Binay Karak
Meridional flow is crucial in generating the solar poloidal magnetic field by facilitating the poleward transport of the field from the decayed Bipolar Magnetic Regions (BMRs). As…

Hysteresis near the transition of the large-scale dynamo in the presence of the small-scale dynamo
Vindya Vashishth
In Sun and solar-type stars, there is a critical dynamo number for the operation of a large-scale dynamo, below which the dynamo ceases to operate. This region is known as the subc…
