Variabilities in the polar field and solar cycle due to irregular properties of Bipolar Magnetic Regions
Pawan Kumar, Bidya Binay Karak, Anu Sreedevi
Decay and dispersal of the tilted Bipolar Magnetic Regions (BMRs) on the solar surface are observed to produce large-scale poloidal field, which acts as the seed for the toroidal f…
Analysis of BMR tilt from AutoTAB catalog: Hinting towards the thin flux tube model?
Anu Sreedevi, Bibhuti Kumar Jha, Bidya Binay Karak +1
One of the intriguing mechanisms of the Sun is the formation of the bipolar magnetic regions (BMRs) in the solar convection zone which are observed as regions of concentrated magne…
AutoTAB: An Algorithm to Track Bipolar Magnetic Regions and Initial results from the Tracked BMRs
Anu Sreedevi, Bibhuti Kumar Jha, Bidya Binay Karak +1
AutoTAB is a state-of-the-art, fully automatic algorithm that tracks the Bipolar Magnetic Regions (BMRs) in magnetogram observations. AutoTAB employs identified BMR regions from Li…
Exploring the Quenching of Bipolar Magnetic Region Tilts using AutoTAB
Bibhuti Kumar Jha, Anu B. Sreedevi, Bidya Binay Karak +1
The tilt of the bipolar magnetic region (BMR) is crucial in the Babcock-Leighton process for the generation of the poloidal magnetic field in the Sun. We extend the work of Jha et…
