Sunburst

It consists of rays or "beams" radiating out from a central disk in the manner of sunbeams.

Traditional sunburst motifs usually show the rays narrowing as they get further from the centre; from the later 19th century they often get wider, as in the Japanese Rising Sun Flag, which is more appropriate in optical terms.

The sunburst motif is characteristic of Baroque church metalwork, especially monstrances and votive crowns, and Art Deco and Art Nouveau styles as well as church architecture.

Sunbursts can appear in photographs when taking a picture of the Sun through the diaphragm of a lens set to a narrow aperture due to diffraction; the effect is often called a sunstar.
