Vector Spectropolarimetry of Dark-cored Penumbral Filaments with Hinode Bellot Rubio ApJL, 2007, in press

BBSO High Resolution Observation Non- uniformity in sunspot penumbra The special term was defined by Scharmer et al., 2002

Physics Manifestation of Magnetic Flux Tubes (Sutterlin et al., 2004, Borrero 2007) Field-Free gaps (Spruit & Scharmer, 2006)

Observing Tool Hinode Solar Optical Telescope --Spectropolarimeter Stokes Q,U,V,I Resolution of 0.3”

Comparison of a sunspot near the limb and at disk center

Conclusion Darker cores are G weaker (are not field free) Dark cores are more inclined (4 degrees) Strong Evershed flow (6-7 km/s)

Limitation The structure is not fully resolved The Stokes inversion is not matured
