Event DetailsEvent Dates: Thursday, February 6, 2014 - 4:00pmSeminar Location: JILA AuditoriumSpeaker Name(s): Wei LiuSpeaker Affiliation(s): Stanford University, Lockheed Martin Solar and Astrophysics Laboratory Seminar Type/SubjectScientific Seminar Type: Astrophysical & Planetary Sciences SeminarEvent Details & Abstract: As the modern civilization becomes more dependent on technology and human beings venture further into space, we are increasingly vulnerable to adverse space weather disturbances. Such disturbances are primarily driven by eruptions originating from the ever dynamic solar corona permeated with million degree, magnetized plasmas. Understanding the dynamics of the corona is of paramount importance for space weather prediction. The solar corona also serves as a unique laboratory for probing similar physics governing plasmas elsewhere in the universe, such as stellar or accretion-disk coronae and planetary magnetospheres. In this talk, I will present recent advances in observing and modeling coronal dynamics related to solar eruptions. Examples will be provided for (1) solar flares, which can produce energetic particles and radiation that impact the Earth, (2) coronal waves, which may play an important role in energy transfer and can be used as diagnostic tools for coronal seismology, and (3) solar prominences, which can be eruptive and critical to the corona-chromosphere mass cycle. I will also discuss implications of these advances beyond solar physics and future prospects with the advent of NSO's Advanced Technology Solar Telescope (ATST).
