Exploring source region of 3-min slow magnetoacoustic waves observed in coronal fan loops rooted in sunspot umbra
Ananya Rawat, Girjesh R. Gupta
Sunspots host various oscillations and wave phenomena like umbral flashes, umbral oscillations, running penumbral waves, and coronal waves. All fan loops rooted in sunspot umbra co…
Formation of an observed eruptive flux rope above the torus instability threshold through tether-cutting magnetic reconnection
Avijeet Prasad, Sanjay Kumar, Alphonse C. Sterling +4
Erupting magnetic flux ropes (MFRs) play a crucial role in producing solar flares. However, the formation of erupting MFRs in complex coronal magnetic configurations and their subs…
Magnetohydrodynamics simulation of magnetic flux rope formation in a quadrupolar magnetic field configuration
Sanjay Kumar, Avijeet Prasad, Sushree S. Nayak +2
Magnetic flux ropes (MFRs) play an important role in high-energetic events like solar flares and coronal mass ejections in the solar atmosphere. Importantly, solar observations sug…
Hall effect on the magnetic reconnections during the evolution of a three-dimensional magnetic flux rope
Kamlesh Bora, Satyam Agarwal, Sanjay Kumar +1
We present a novel Hall magnetohydrodynamics (HMHD) numerical simulation of a three-dimensional (3D) magnetic flux rope (MFR) -- generated by magnetic reconnections from an initial…
A study of the propagation of magnetoacoustic waves in small-scale magnetic fields using solar photospheric and chromospheric Dopplergrams: HMI/SDO and MAST observations
Hirdesh Kumar, Brajesh Kumar, S. P. Rajaguru +2
In this work, we present a study of the propagation of low-frequency magneto-acoustic waves into the solar chromosphere within small-scale inclined magnetic fields over a quiet-mag…
