SDO, the Sun, the Universe

Dean Pesnell, NASA / GSFC

ABSTRACT: The Sun is our best example for how stars evolve and behave. It is the only star whose surface is well-resolved in time and space. It is the only star which local helioseisomology can look into and through. One tool we to study the Sun is the Solar Dynamics Observatory (SDO), a NASA satellite that has been returning data for seven years. SDO focuses on the variations in the Sun caused by changes in the magnetic field generated by the convection zone.I will describe some aspects of SDO science that can be directly related to Sun-like stars. First are spectral irradiance measurements in extreme ultraviolet wavelengths that contribute to the loss of planetary atmospheres. Next are failed filament eruptions that fall back onto the surface as a form of accretion. Finally, how the magnetic field evolves from solar minimum to maximum and back is giving us clues about predicting that magnetic field. Please come and have a look at how studying the Sun informs our knowledge of stars.
