Solar differential rotation driven by baroclinic forcing
L. S. Menicucci, G. Guerrero, M. Dikpati +3
A combination of recent observations and numerical simulations has called into question whether Sun's interior is characterized by strong turbulent convection, a problem known as c…
Analysis of Short-term Solar Activity Variability and Estimating the Timings of the Next Enhanced Bursts
Juie Shetye, Mausumi Dikpati
We present a hybrid forecasting strategy that combines numerical modeling, statistical forecasting, and machine learning methods to predict enhanced bursts of solar activity. These…
Moderate Nesting and Cross-Equatorial Asymmetry of Active Regions in Solar Cycle 24
Aimee Norton, Alex Mendez, Ruizhu Chen +2
Solar Cycle 24 data are used to determine how often the Sun emerges sunspots in `activity nests', i.e., regions where sunspots and active regions (ARs) repeatedly emerge. We use th…
Simulations of the onset and dynamical evolution of inertial waves in solar/stellar interior
Mariane D. Souza-Gomes, Conrado S. Finotti, Gustavo Guerrero +4
Inertial modes have been recently detected in the Sun via helioseismology, yet their origin, evolution, and role in the dynamics of the solar plasma and magnetic field remain poorl…
A Physics Informed Neural Network For Deriving MHD State Vectors From Global Active Regions Observations
Subhamoy Chatterjee, Mausumi Dikpati
Solar active regions (ARs) do not appear randomly but cluster along longitudinally warped toroidal bands ('toroids') that encode information about magnetic structures in the tachoc…
Solar Interior
Mark Linton, Mausumi Dikpati, Rachel Howe
This chapter introduces the reader to the solar interior, in particular the convection zone. The first section explores the solar cycle and the dynamo models that have been studied…
