Observing and Modeling the Sun-Earth System

Matthias Rempel, et al. combine cutting-edge solar astronomy with advanced computer science to analyze data from the world’s largest ground-based solar telescope located atop Haleakalā, Maui. See featured story from the University of Hawaiʻi News. The team’s research recently published in Astrophysical Journal focuses on their development of deep learning models that rapidly analyze vast amounts of data from the U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope. 

HAO scientist Mausumi Dikpati's recent significant publication entitled "A Magnetohydrodynamic Mechanism for the Formation of Solar Polar Vortices" is highlighted by NSF-NCAR news website. Dikpati and her co-authors report the first magnetohydrodynamic nonlinear simulations for the formation and evolution of solar polar vortices using a near-surface magnetohydrodynamic shallow-water model. 

For the first time, scientists, including  lead author Newkirk graduate student Zihao Yang, have taken near-daily measurements of the Sun’s global coronal magnetic field, a region of the Sun that has only been observed irregularly in the past. The resulting observations are providing valuable insights into the processes that drive the intense solar storms that impact fundamental technologies, and thus lives and livelihoods, here on Earth.
