Association of Plages With Sunspots: A multi wavelength Study Using Kodaikanal Ca K and Greenwich sunspot area Data
Sudip Mandal, Subhamoy Chatterjee, Dipankar Banerjee
Plages are the magnetically active chromospheric structures prominently visible in Ca K line (3933.67 Å). A plage may or may not be associated with a sun…
Solar Active Longitudes From Kodaikanal White-light Digitized Data
Sudip Mandal, Subhamoy Chatterjee, Dipankar Banerjee
The study of solar active longitudes has generated a great interest in the recent years. In this work we have used an unique continuous sunspot data series obtained from Kodaikanal…
Sunspot Sizes and The Solar Cycle: Analysis Using Kodaikanal White-light Digitized Data
Sudip Mandal, Dipankar Banerjee
Sizes of the sunspots vary in a wide range during the progression of a solar cycle. Long-term variation study of different sunspot sizes are key to better understand the underlying…
Kodaikanal Digitized White-light Data Archive (1921-2011): Analysis of various solar cycle features
Sudip Mandal, Manjunath Hegde, Tanmoy Samanta +3
Long-term sunspot observations are key to understand and predict the solar activities and its effects on the space weather.Consistent observations which are crucial for long-term v…
Reflection Of Propagating Slow Magneto-acoustic Waves In Hot Coronal Loops : Multi-instrument Observations and Numerical Modelling
Sudip Mandal, Ding Yuan, Xia Fang +3
Slow MHD waves are important tools for understanding the coronal structures and dynamics. In this paper, we report a number of observations, from X-Ray Telescope (XRT) on board HIN…
Forward Modelling of Propagating Slow Waves in Coronal Loops and Their Frequency-Dependent Damping
Sudip Mandal, Norbert Magyar, Ding Yuan +2
Propagating slow waves in coronal loops exhibit a damping which depends upon the frequency of the waves. In this study we aim to investigate the relationship of the damping length…
