Presentation Transcript

  1. G-Band Images from MHD Convection Simulations Robert Stein - Mich. State Univ. Mats Carlsson - Oslo Univ. Aake Nordlund - NBIfAFG Goran Scharmer - Roy. Swedish Acad. Sci.

  2. G-Band Spectrum

  3. G-band image & magnetic field contours (-.3,1,2 kG)

  4. Magnetic concentrations: cool, low r,low opacity.Towards limb,radiation emerges from hot granulewalls behind.On optical depth scale,magneticconcentrations are hot, contrast increases with opacity

  5. Temperature structure: Granule (G) Intergranular lane (IG) G-band bright point (BP) Dark flux concentration (FC) *T=Tgband +T=Tgcont

  6. Striated Bright Walls Observed

  7. G-band image & magnetic field contours (-.3,1,2 kG)

  8. Dark striations: weaker B larger r see higher cooler layer
