Holly Gilbert awarded the 2025 Irene González Hernández Prize
HAO is proud to announce that our director, Holly Gilbert, is the recipient of the 2025 Irene González Hernández Prize. As quoted from the SPD website announcement..."The Irene González Hernández Prize, established in 2024, celebrates mid-career scientists for transformative contributions to solar research, leadership, and community service." Congratulations Holly!

Cutting-edge SPIn4D project combines AI and Astronomy
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.

A Magnetohydrodynamic Mechanism for the Formation of Solar Polar Vortices
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.
Latest Research Highlights

A Study on the Nested Rings CME Structure Observed by the WISPR Imager Onboard Parker Solar Probe
Published: December 2024. Sarah Gibson, et al. present an analysis of a CME and its interior structure observed during the seventh solar encounter of the Parker Solar Probe, utilizing the data from its Wide-Field Imager for Solar PRobe (WISPR) heliospheric imager. They observe a complex CME structure consisting of non-concentric nested rings, which we argue is a signature of the embedded helical magnetic flux rope (MFR) of the CME.

Evolution Of Amplitude And Longitude Phase Of Tachocline Rossby Waves Diffusing To The Photosphere
Published: 05 November 2024. Mausumi Dikpati, Peter A Gilman, Breno Raphaldini, Scott W McIntosh improve on the 2020 MHD Rossby wave model to include a hydrodynamic turbulent convection zone (CZ). This new approach enabled them to examine how MHD Rossby waves generated in the tachocline might diffuse upward through the CZ to the solar surface.

SynCOM: An Empirical Model for High-Resolution Simulations of Transient Solar Wind Flows
Published: November 2024. Sarah Gibson, V. P. Moraes Filho, V. Uritsky, B. J. Thompson, and C. E. DeForest demonstrate how SynCOM can be employed to assess the precision and performance of two different flow tracking methods. By providing a ground-truth based on observational data, we highlight the importance of SynCOM in confirming observational standards for detecting coronal flows.
