Scientific research with THEMIS
THEMIS is an infrastructure at the forefront of contemporary research in the fields of solar physics, inner planetary physics as well as solar instrumentation. The complete description of its scientific objectives can be found on the dedicated webpage. In summary, its key scientific objectives are:
- Instrumental development in high-resolution spectropolarimetry & spectroscopy: analyzing the electromagnetic spectrum and the polarization of the light to infer multiple properties of the observed celestial body
- Solar adaptive optics:
- Understand solar magnetism : thanks to its spectropolarimetric capabilities, THEMIS performs magnetic field measurements of the visible light that has been polarized by the presence of magnetic field in the solar atmosphere
- Understand solar heating : THEMIS aims to understand the coupling between different layers of the solar atmosphere and how energy is transported from the interior to the outer solar atmosphere.
- Study and follow solar activity : THEMIS investigates transient events and dynamic processes in the Sun's atmosphere, such as protuberances, prominences, jets, flares, solar eruptions.
- Monitor solar origin of space weather: by improving our understanding of the Sun's magnetic activity and its role in driving solar phenomena, THEMIS contributes valuable data for space weather prediction and understanding the Sun-Earth relationships.
- Study of inner solar system objects: THEMIS offers without equivalent ground-based observational capabilities of near-Sun objects such as Mercury and comets. THEMIS's high spectral resolution can allow detailed observations of the atmospheres of Mercury and measurement of chemical compositions via spectroscopy.
