Mathematician Uses Custom Gear and Algorithms to Study Solar Corona During Eclipses
Key points
- Miloslav Druckmüller studies solar corona during eclipses.
- Team uses custom optical instruments with eight astrocameras.
- Each camera has spectral filters for specific iron ion emissions.
- Analyzing iron ion locations reveals corona heat distribution.
Eclipse Chasing for Science
Miloslav Druckmüller and his team conduct research during total solar eclipses, utilizing specialized equipment to observe the sun's outer atmosphere, the corona. This work involves setting up portable telescopes and cameras connected to laptops in locations within the path of totality, such as the plains of Castile and León in Spain.
Custom Instrumentation for Corona Analysis
Druckmüller designed and built a unique optical instrument comprising eight astrocameras. Each camera is fitted with a spectral filter designed to detect and record specific emission spectra originating from the solar corona. These spectra are linked to particular ionic species of iron atoms.
Mapping Coronal Temperature
The temperature required to ionize iron varies depending on the specific ionic species. By analyzing the locations and relative abundance of these different iron ionic species, researchers can gain insights into the distribution of heat within the solar corona. This method aims to address long-standing questions about the sun's outer atmosphere.
Decades of Development
Druckmüller has spent decades developing the custom-built telescope systems and image-processing techniques used in this research. His experience includes observing 19 solar eclipses, demonstrating a long-term commitment to this specialized field of solar physics.
