Researchers use helioseismology to track sound waves inside the Sun, finding a gradual change in structure just beneath the surface that spans multiple cycles. This discovery reveals a shift towards more tightly confined magnetic activity near the surface, with implications for space weather predictions.
A new tool developed by Southwest Research Institute and National Science Foundation's National Center for Atmospheric Research provides a first step toward forecasting space weather weeks in advance. The PINNBARDS framework connects surface observations of solar active regions to deep solar magnetic dynamics, offering potential for su...
A new study uses helioseismic techniques to provide an independent measurement of solar radiative opacity, confirming recent experimental results and revealing gaps in atomic physics understanding. The research improves stellar modeling accuracy, impacting galactic evolution and fusion energy research.
A Southwest Research Institute-led team developed a revised solar composition that potentially reconciles spectroscopy and helioseismology measurements for the first time. The new solar composition suggests higher levels of carbon, nitrogen, and oxygen in the Sun than previously thought.
An international team developed a new theoretical model that solves part of the 'solar problem' by considering the Sun's rotation and magnetic fields. The results reproduce the concentration of helium and lithium in the Sun's outer layers, providing insights into stellar physics.
Researchers from NYU Abu Dhabi used helioseismology to analyze the Sun's interior and found that the meridional flow is a single cell in each hemisphere. This process determines the characteristics of the sunspot cycle, supporting the flux-transport dynamo model.
The Royal Astronomical Society has awarded its highest honors to Professor Sandra Moore Faber and Professor Yvonne Elsworth for their groundbreaking research in galaxy structure, cosmology, and solar physics. Their achievements have significantly advanced our understanding of the universe.
Scientists have overturned previous notions of how the sun's writhing insides move from equator to pole and back again. The team found a double-layered circulation system with two cycles on top of each other, providing new opportunities for studying solar magnetism and cycles.
Scientists have developed a new imaging technique using ripples on the sun's surface to probe its interior and locate hidden solar storms. This breakthrough enables forecasting of solar storms with a week's warning, potentially disrupting spacecraft and power systems.
