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…
Analysis of sudden variations in photospheric magnetic fields during a large flare and their influences in the solar atmosphere
Brajesh Kumar, A. Raja Bayanna, P. Venkatakrishnan +1
The solar active region NOAA 11719 produced a large two-ribbon flare on 11 April 2013. We have investigated the sudden variations in the photospheric magnetic fields in this active…
Can major solar flares excite high-frequency global waves in the Sun ?
Brajesh Kumar, Savita Mathur, R. A. Garcia +1
The study of low-degree high-frequency waves in the Sun can provide new insight into the dynamics of the deeper layers of the Sun. Here, we present the analysis of the velocity obs…
