Pivot of the Emerging Bipolar Magnetic Region in the Birth of Sigmoidal Solar Active Regions
Ronald L. Moore, Sanjiv K. Tiwari, V. Aparna +3
We present an augmentation to longstanding evidence from observations and MHD modeling that (1) every solar emerging bipolar magnetic region (BMR) is made by an emerging omega-loop…

Quantifying Suppression of Solar Surface Magnetic Flux Advection with Increasing Field Strength
V. Aparna, Sanjiv K. Tiwari, Ronald L. Moore +4
One of the main theories for heating of the solar corona is based on the idea that solar convection shuffles and tangles magnetic field lines to make many small-scale current sheet…
