Spectroscopic diagnostics of coronal fan loops using EIS/Hinode and AIA/SDO
Ananya Rawat, Girjesh Gupta
We utilize spectroscopic and imaging data from the EIS/Hinode and the AIA/SDO to determine plasma and wave parameters along coronal fan loops. We determined the temperature along t…
Investigating the propagation of small-scale flare energy in the lower and upper atmosphere of solar active region
Girjesh Gupta, Ananya Rawat, Helen Mason +1
During solar flares, a considerable portion of the flare atmosphere becomes heated; however, the energy deposition process is still unclear, especially in the lower solar atmospher…
Understanding the magnetic field and plasma- along umbral fan loops traced using 3-min slow waves
Ananya Rawat, Girjesh Gupta, Tom Van Doorsselaere +2
The plasma- is an important fundamental physical quantity in solar plasma physics, which determines the dominating process in the solar atmosphere, i.e., magnetic or thermodynam…
Effect of area divergence and frequency on damping of slow magnetoacoustic waves propagating along umbral fan loops
Ananya Rawat, Girjesh R. Gupta
Waves play an important role in the heating of solar atmosphere, however, observations of wave propagation and damping from the solar photosphere to corona through chromosphere and…
Exploring magnetic coupling of solar atmosphere through frequency modulations of 3-min slow magnetoacoustic waves
Ananya Rawat, Girjesh Gupta
Coronal fan loops rooted in sunspot umbra show outward propagating waves with subsonic phase speed and period around 3-min. However, their source region in the lower atmosphere is…
