| SOLAR SURFACE: | |
 |
On the surface of the sun, energy can be suddenly released in a process called a solar flare. Solar flares have been associated with magnetic reconnection. They can produce solar storms and influence space weather. Our goals in this area include:

| SOLAR WIND, SPACE WEATHER, AND SPACE CLIMATE: | |
 |
Plasma ejected from a star escapes the gravity field to produce a stellar wind. Stellar winds, including the solar wind, stream away from the star at high velocities and interact with energetic particles. The solar wind is a key driver for the space weather and space climate that affects Earth. Our activities in this area include: |
| STELLAR INTERIORS AND STELLAR EVOLUTION: | |
 |
Plasma flows in the deep interior of stars produce magnetic fields via the dynamo mechanism. Nonlinear plasma phenomena in the stellar interior can profoundly affect the evolution and internal structure of a star during different phases of its life. Plasma phenomena require sophisticated modeling and massive multidimensional simulations in order to provide clear interpretation and new models for observational data. We study: |
| HELIOSEISMOLOGY AND ASTROSEISMOLOGY: | |
 |
Oscillation of waves in the sun can be used to infer its internal structure, an area called helioseismology. Recent surveys targeted toward exoplanets have produced a wealth of new data on waves of other stars, an area called astroseismology. Our goals in this area include: |
| ASTROINFORMATICS: | |
| Astroinformatics is the use of computational methods for data analysis and simulation to approach problems in astrophysics. Learn more here. | |
