Finding the critical decay index in solar prominence eruptions
N. Vasantharaju, P. Vemareddy, B. Ravindra +1
The background field is assumed to play prime role in the erupting structures like prominences. In the flux rope models, the critical decay index () is a measure of the rate a…
Degree of electric current neutralization and the activity in solar Active Regions
P. Vemareddy
Using time-sequence vector magnetic field observation from \textit{Helioseismic and Magnetic Imager}, we examined the connection of non-neutralized currents and the observed activi…
Formation and eruption of sigmoidal structure from a weak field region of NOAA 11942
N. Vasantharaju, P. Vemareddy, B. Ravindra +1
Using observations from Solar Dynamics Observatory, we studied an interesting example of a sigmoid formation and eruption from small-scale flux canceling regions of active region (…
Very fast helicity injection leading to critically stable state and large eruptive activity in solar active region NOAA 12673
P. Vemareddy
Using the photospheric magnetic and coronal observations of Solar Dynamics Observatory, we studied the build-up and eruption of coronal non-potential magnetic structure in emerging…
