Living With a Star's Solar Dynamics Observatory research connects to many areas of solar physics and many other solar missions. Tracing these connections allows us to build a more accurate understanding of the Sun and solar activity. The workshop will focus on our improved knowledge and understanding of the Sun’s magnetic field that have come from the SDO data, and what will come in the future. Scientific sessions will feature a broad spectrum of science topics fundamental to SDO's science investigations: Atmospheric Imaging Assembly (AIA), EUV Variability Experiment (EVE), and Helioseismic and Magnetic Imager (HMI), as well as the overlap between SDO and other scientific missions and activities. We invite you to celebrate the breadth of research topics enabled by SDO during its Prime Mission and the First Extended Mission. Join us!

 Scientific Sessions

  1. Motions Inside the Sun
    Invited Speaker: Ariane Schad, Kiepenheuer-Institut für Sonnenphysik, “Measuring flows in the solar interior: current developments, results, and outstanding problems”

    One of the principal goals of the HMI investigation is to better characterize flows in the solar interior. Solar dynamics are a critical component of solar activity on both global scales and local scales. Of particular interest is the very difficult problem of finding the return flow (or flows) of meridional circulation. Other interesting areas of current research involve solar differential rotation, especially at high latitudes, and differences between the current solar cycle and previous ones; the characterization of local flow structures; and the calibration and improvement of far-side imaging techniques.
  2. Motions Near and Above the Solar Surface
    Invited Speaker: David Jess, Queen's University Belfast, "Motions Near and Above the Solar Surface captured in the SDO Era"

    In this session, we will focus on the measurements and analysis of localized flow structures, MHD waves, and other instabilities in the solar atmosphere. Coronal seismology and studies of sunquakes as tools to understand the solar atmospheric responses to perturbations will be included in the discussions.
  3. Solar Magnetic Variability and the Solar Cycle
    Invited Speaker: Andreas Munoz-Jaramillo, Georgia State University, "Advances in Our Understanding of Solar Cycle Propagation and Predictability"
    What have we learned from nearly continuous sampling of the solar magnetic field with space-based instruments for almost an entire 22-year solar cycle? How does the solar magnetic field evolve over these long timescales? How do irradiances vary over the solar cycle and how are those variations related to the magnetic field? Have we gotten any better at the predicting magnetic activity five years and longer into the future? This session will cover the solar magnetic field, describing its variation, from small-scale fields to the global solar field, over timescales longer than rotations.
  4. The Evolution of Active Regions
    Invited Speaker:  Lucie Green, Mullard Space Science Lab/University College London, "The Evolution of Active Regions"

    Although Cycle 24 is weaker than recent cycles, plenty of intriguing sunspots have been observed. We dedicate this session to studies of active regions: their emergence and decay, subsurface structure and flows, twist, tilt and helicity. In addition, filament and prominence formation and evolution (but not eruption), are part of the topics slated for discussion. The thermal evolution of active regions as a cause for irradiance variations ties together how surface magnetism modulates the solar output.
  5. Studies of Solar Eruptive Events (SEEs) 
    Invited Speaker:  Mark Linton, Naval Research Laboratory "Modeling the Energization and Eruption of Flux Ropes and Sheared Arcades"

    Since its commissioning in 2010, SDO has observed 40+ X-class flares and hundreds of M-class flares. SDO's broad coverage in the spatiotemporal and thermal domains facilitates detailed case studies (using complementary data from other observatories) and ensemble studies of solar flares and eruptive events. For this session, we invite contributions addressing any of the following topics:
    • Distinguishing active regions as sites of eruptive vs. non-eruptive events (how has SDO data improved predictions of flares and other eruptive events, machine learning)
    • Flux rope and prominence destabilization
    • SEE energetics and particle acceleration
    • On-disk CME detection
    • Coronal dimmings as CME proxy
    • EUV spectral irradiance evolution during flares
  6. Atmospheric Dynamics and Sources of the Solar Wind
    Invited Speaker: Jon Linker, Predictive Science Inc., “Are Dynamical Sources Essential for the Production of the Ambient Solar Wind?”

    The large-scale atmospheric dynamics and structures of the Sun are crucial for understanding the origin and evolution of the solar wind. This session will review our current knowledge about large-scale solar structures (e.g., coronal holes, helmet streamers, current sheet), global field topology, and thermodynamics and mass regulation that connecting photosphere, chromosphere, corona, and into the heliosphere. In addition, this session will highlight the benefit of SDO data on improving the data-inspired, data-constrained, and data-driven models that facilitate our understanding of the Sun and heliosphere.
  7. Space Weather at the Earth and other Planets
    Invited Speaker: Christina Lee, Space Sciences Lab, UC Berkeley, "Influence of the Sun on the Space Weather Conditions: Cycle 24 Observations from 1 AU to Mars”
    The health and safety of both technology and humans on Earth and in space requires knowledge of the ever-changing space environment in which we live, travel, and operate. One of the goals of the Solar Dynamics Observatory mission has been to do the foundational research that would lead to improved space weather prediction and specification (forecasting and nowcasting). This session focuses on the advances in our knowledge of space weather and its impacts brought about by SDO through measurements and modeling. Topics include, but are not limited to: the impacts solar eruptive events on Earth and other planets, extreme space weather events (such as super-flares), solar wind and cosmic ray modulation, flux rope propagation and magnetic clouds, and solar irradiance variations and their impacts throughout the solar system.
  8. The Sun as a Star
    Invited Speaker: Anne-Marie Broomhall, University of Warwick, “Seismology tools for studying the solar-stellar connection”

    The Sun is just one star among many. The past decade has seen extraordinary progress in studying other stars using techniques similar to the ones we use to study the inside of the Sun. At the same time, the questions of interest to the stellar astronomers are still being asked about the Sun. This session will allow for discussion of what helio- and asteroseismology can tell us about the global properties of stars including our Sun.
