Main sequence star

A generic stable hydrogen-burning main-sequence star shown in simple textbook or clipart style as a nearly perfect circular stellar disk or glowing sphere. It appears compact, clean, and highly symmetrical, with a bright white-yellow, yellow-white, or blue-white center that fades through a smooth radial gradient toward a slightly darker pale yellow, golden, yellow-orange, soft orange, or faintly blue outer edge depending on stellar temperature. The photosphere is mostly smooth and featureless, with at most very subtle mottling, and the star has a crisp round outline surrounded by a soft diffuse luminous halo. No eruptions, extended envelope, asymmetry, labels, background elements, or dramatic surface texture are present.
