Extreme Ultraviolet Microflashes at Plume Bases: A Candidate for Powering the Corona and Solar Wind?
Navdeep K. Panesar, Sanjiv K. Tiwari, Meng Jin +4
Solar plumes - outflows of bright coronal plasma - are a major component of the open-magnetic-field corona and solar wind, but their driving mechanism remains uncertain. Here we re…

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…
