Microwave Polar Brightening and Its Connection to Polar Coronal Holes
Rohan Bose, Anshu Kumari, Vaibhav Pant +3
Polar brightening (PB) observed at microwave frequencies serves as an important probe to study the thermal and magnetic properties in the Sun's polar regions. Building on earlier s…
Radio Signature of Higher Atmospheric Meridional Flow and Implications for Magnetic Trees in the Sun
Srinjana Routh, Anshu Kumari, Rohan Bose +4
The coupling between plasma flows and magnetic fields in the solar atmosphere governs the transport of angular momentum and the redistribution of magnetic flux, yet its manifestati…
Machine Learning Based Identification of Solar Disk and Plages in Kodaikanal Solar Observatory Historical Suncharts
Dibya Kirti Mishra, Subhamoy Chatterjee, Bibhuti Kumar Jha +6
Kodaikanal Solar Observatory (KoSO) is one of the oldest solar observatories, possessing an archive of multi-wavelength solar observations, including white light, Ca II K, and H-al…
Polar Filaments Capture High Latitude Solar Poloidal Field Interactions and can Foretell the Future Sunspot Cycle Amplitude before Polar Field Precursors
Srinjana Routh, Shaonwita Pal, Dibyendu Nandy +3
Polar fields at the minimum of a sunspot cycle -- which are a manifestation of the radial component of the Sun's poloidal field -- are deemed to be the best indicator of the streng…
Insights into Chromospheric Large-Scale Flows using Nobeyama 17 GHz Radio Observations I. The Differential Rotation Profile
Srinjana Routh, Anshu Kumari, Vaibhav Pant +4
Although the differential rotation rate on the solar surface has long been studied using optical and extreme ultraviolet (EUV) observations, associating these measurements to speci…
Exploring the variation in the dynamic rotation profile of the hotter solar atmosphere using mutliwavelength data
Srinjana Routh, Bibhuti Kumar Jha, Dibya Kirti Mishra +4
The global rotational profile of the solar atmosphere and its variation at different layers, although crucial for a comprehensive understanding of the dynamics of the solar magneti…
