X-Ray and Ultraviolet Flares on AT Microscopii Observed by AstroSat
Alexey A. Kuznetsov, Ruslan R. Karakotov, Kalugodu Chandrashekhar +1
We present observations of the active M-dwarf binary AT Mic (dM4.5e+dM4.5e) obtained with the orbital observatory AstroSat. During 20 ks of observations, in the far ultraviolet ($1…
Power distribution of oscillations in the atmosphere of a plage region: Joint observations with ALMA, IRIS and SDO
Nancy Narang, Kalugodu Chandrashekhar, Shahin Jafarzadeh +3
We present a statistical analysis of power distribution of oscillations in a plage region in active region NOAA AR12651, observed jointly with ALMA (Atacama Large Millimeter/Submil…
Statistical Study of Plasmoids associated with post-CME Current Sheet
Ritesh Patel, Vaibhav Pant, K. Chandrashekhar +1
We investigate the properties of plasmoids observed in the current sheet formed after an X-8.3 flare followed by a fast CME eruption on September 10, 2017 using Extreme Ultraviolet…
Association of calcium network bright points with underneath photospheric magnetic patches
Nancy Narang, Dipankar Banerjee, Kalugodu Chandrashekhar +1
Recent dedicated Hinode polar region campaigns revealed the presence of concentrated kilogauss patches of magnetic field in the polar regions of the Sun which are also shown to be…
Microwave imaging of a hot flux rope structure during the pre-impulsive stage of an eruptive M7.7 solar flare
Z. Wu, Y. Chen, G. Huang +7
Corona structures and processes during the pre-impulsive stage of solar eruption are crucial to understanding the physics leading to the subsequent explosive energy release. Here w…
Damping and power spectra of quasi-periodic intensity disturbances above a solar polar coronal hole
Fangran Jiao, Lidong Xia, Zhenghua Huang +4
We study intensity disturbances above a solar polar coronal hole seen in the AIA 171 Å and 193 Å passbands, aiming to provide more insights into their physical nature. The damping…
Sources of quasi-periodic propagating disturbances above a solar polar coronal hole
Fangran Jiao, Lidong Xia, Bo Li +5
Quasi-periodic propagating disturbances (PDs) are ubiquitous in polar coronal holes on the Sun. It remains unclear as to what generates PDs. In this work, we investigate how the PD…
Modeling solar coronal bright point oscillations with multiple nanoflare heated loops
K. Chandrashekhar, Aveek Sarkar
Intensity oscillations of coronal bright points (BPs) have been studied for past several years. It has been known for a while that these BPs are closed magnetic loop like structure…
Characteristics of polar coronal hole jets
K. Chandrashekhar, A. Bemporad, D. Banerjee +2
High spatial- and temporal-resolution images of coronal hole regions show a dynamical environment where mass flows and jets are frequently observed. These jets are believed to be i…
The dynamical behaviour of a jet in an on-disk coronal hole observed with AIA/SDO
K. Chandrashekhar, R. J. Morton, D. Banerjee +1
EUV jets situated in coronal holes are thought to play an important role in supplying heated material to the corona and solar wind. The multi-wavelength capabilities and high signa…
Dynamics of Coronal Bright Points as seen by Sun Watcher using Active Pixel System detector and Image Processing (SWAP), Atmospheric Imaging Assembly AIA), and Helioseismic and Magnetic Imager (HMI)
K. Chandrashekhar, S. Krishna Prasad, D. Banerjee +2
The \textit{Sun Watcher using Active Pixel system detector and Image Processing}(SWAP) on board the \textit{PRoject for OnBoard Autonomy\todash 2} (PROBA\todash 2) spacecraft provi…
