Magnetic field dependence of bipolar magnetic region tilts on the Sun: Indication of tilt quenching
Bibhuti Kumar Jha, Bidya Binay Karak, Sudip Mandal +1
The tilt of bipolar magnetic region (BMR) is crucial in the Babcock--Leighton process for the generation of the poloidal magnetic field in Sun. Based on the thin flux tube model of…
Study of Sunspot Penumbra to Umbra Area Ratio using Kodaikanal White-light Digitized Data
Bibhuti Kumar Jha, Sudip Mandal, Dipankar Banerjee
We study the long-term behaviour of sunspot penumbra to umbra area ratio by analyzing the recently digitized Kodaikanal white-light data (1923-2011). We implement an automatic umbr…
Can the long-term hemispheric asymmetry of solar activity result from fluctuations in dynamo parameters?
Alexander Nepomnyashchikh, Sudip Mandal, Dipankar Banerjee +1
The hemispheric asymmetry of sunspot activity observed possesses a regular component varying on a time scale of several solar cycles whose origin and properties are currently debat…
