On the Response of the Transition Region and the Corona to Rapid Excursions in the Chromosphere
Ravi Chaurasiya, Ankala Raja Bayanna, R. E. Louis +2
Spicules are the thin hair/grass-like structures that are prominently observed at the chromospheric solar limb. It is believed that fibrils and rapid blueshifted and redshifted exc…
Investigation of Phase Shift and Travel Time of Acoustic Waves in the Lower Solar Atmosphere Using Multi-Height Velocities
Hirdesh Kumar, Brajesh Kumar, Shibu K. Mathew +2
We report and discuss phase-shift and phase travel time of low-frequency (ν < 5.0 mHz) acoustic waves estimated within the photosphere and photosphere-chromosphere interface region…
Classification of circular polarization Stokes profiles in a sunspot using k-means clustering
Rohan Eugene Louis, Shibu K. Mathew, A. Raja Bayanna
The magnetic and velocity fields in sunspots are highly structured on small spatial scales which are encoded in the Stokes profiles. Our aim is to identify Stokes profiles in a sun…
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…
