Welcome

The Solar and Heliospheric Research Group seeks a greater Understanding of the diverse plasma processes at work throughout our solar system and the universe. Research topics range from the physics of the solar interior and atmosphere to the solar wind, energetic particle transport, and acceleration processes.
