U+22C6 "⋆" Star Operator Unicode Character

U+22C6 "⋆" Star Operator is a mathematical symbol that represents a binary operation in algebra and set theory, often used to denote convolution, the star product in free probability, or other abstract multiplicative operations. It appears as a small, low-positioned star, distinct from the more common asterisk (*) or star (*) shaped glyphs, and is typically used in contexts like group theory, ring theory, and operator algebras to indicate a specific, often noncommutative or high-level operation between elements.
