Impact of Anomalous Active Regions on the Large-scale Magnetic Field of the Sun (2023)
Journal Article
Pal, S., Bhowmik, P., Mahajan, S. S., & Nandy, D. (2023). Impact of Anomalous Active Regions on the Large-scale Magnetic Field of the Sun. Astrophysical Journal, 953(1), Article 51. https://doi.org/10.3847/1538-4357/acd77e

One of the major sources of perturbation in the solar cycle amplitude is believed to be the emergence of anomalous active regions that do not obey Hale's polarity law and Joy's law of tilt angles. Anomalous regions containing high magnetic flux that... Read More about Impact of Anomalous Active Regions on the Large-scale Magnetic Field of the Sun.

Physical Models for Solar Cycle Predictions (2023)
Journal Article
Bhowmik, P., Jiang, J., Upton, L., Lemerle, A., & Nandy, D. (2023). Physical Models for Solar Cycle Predictions. Space Science Reviews, 219(5), Article 40. https://doi.org/10.1007/s11214-023-00983-x

The dynamic activity of stars such as the Sun influences (exo)planetary space environments through modulation of stellar radiation, plasma wind, particle and magnetic fluxes. Energetic solar-stellar phenomena such as flares and coronal mass ejections... Read More about Physical Models for Solar Cycle Predictions.

Causality in heliophysics: Magnetic fields as a bridge between the Sun’s interior and the Earth’s space environment (2023)
Journal Article
Nandy, D., Baruah, Y., Bhowmik, P., Dash, S., Gupta, S., Hazra, S., …Sinha, S. (2023). Causality in heliophysics: Magnetic fields as a bridge between the Sun’s interior and the Earth’s space environment. Journal of Atmospheric and Solar-Terrestrial Physics, 248, Article 106081. https://doi.org/10.1016/j.jastp.2023.106081

Our host star, the Sun, is a middle-aged main sequence G type star whose activity varies. These variations are primarily governed by solar magnetic fields which are produced in the Sun’s interior via a magnetohydrodynamic dynamo mechanism. Solar acti...
