Large ephemeral regions and their tilt angles
Rambahadur Gupta, Anu Sreedevi, Bibhuti Kumar Jha +1
The ephemeral regions (ERs), which are short-lived bipolar magnetic regions that emerge across the solar cycle but do not appear as sunspots, play a crucial role in the Sun's magne…
Variation of the sunspot area during the rising and declining phases of the solar cycle supports the toroidal flux loss due to flux emergence
Bidya Binay Karak, Soumya Mishra, Anu Sreedevi
Sunspots are obvious observable manifestations of the toroidal magnetic field generated through the dynamo in the convection zone. They appear in different sizes, having a wide dis…
Observed Joys law of Bipolar Magnetic Region tilts at the emergence supports the thin flux tube model
Anu Sreedevi, Bidya Binay Karak, Bibhuti Kumar Jha +2
Bipolar sunspots, or more generally, Bipolar Magnetic Regions, BMRs, are the dynamic magnetic regions that appear on the solar surface and are central to solar activity. One striki…
Backtracking Bipolar Magnetic Regions to their emergence: Two groups and their implication in the tilt measurements
Anu Sreedevi, Bidya Binay Karak, Bibhuti Kumar Jha +2
Bipolar Magnetic Regions (BMRs) that appear on the solar photosphere are surface manifestations of the Suns internal magnetic field. With modern observations and continuous data st…
Role of sunspot latitude versus tilt in determining the polar field and amplitude of the next cycle: Cause of the weak Solar Cycle 20
Bidisha Dey, Anu Sreedevi, Bidya Binay Karak
One prominent feature of solar cycle is its irregular variation in its cycle strength, making it challenging to predict the amplitude of the next cycle. Studies show that fluctuati…
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…
AutoTAB: Automatic Tracking Algorithm for Bipolar Magnetic Regions
Anu Sreedevi, Bibhuti Kumar Jha, Bidya Binay Karak +1
Bipolar Magnetic Regions (BMRs) provide crucial information about solar magnetism. They exhibit varying morphology and magnetic properties throughout their lifetime, and studying t…
