Luc Rouppe van der Voort: "Observations of small-scale magnetic structures on the Sun"

Fredagskollokvium

Abstract.

Small-scale magnetic structures can be seen in G-band filtergrams as isolated bright points, strings of bright points and dark micro-pores. I will present observations of these structures obtained with the Swedish 1-meter Solar Telescope on La Palma that reach the diffraction limit of the telescope. At a resolution of 0"1, new forms of magnetic structures are found in strong field areas: elongated "ribbons" and more circular "flowers". Time-series of observations show the dynamical evolution of these structures.
