Star domain - Wikipedia
WEBIn geometry, a set in the Euclidean space is called a star domain (or star-convex set, star-shaped set [1] or radially convex set) if there exists an such that for all , the line segment from to lies in .
Stellar magnetic field - Wikipedia
WEBA stellar magnetic field is a magnetic field generated by the motion of conductive plasma inside a star. This motion is created through convection, which is a form of energy transport involving the physical movement of material.
The relationship between two definitions of star-shaped domain
WEBJul 28, 2014 · There are two definitions of star-shaped domain. One is given in wikipedia as follows. Def1: A set S in the Euclidean space Rn is called a star domain (or star-convex set, star-shaped or radially convex set) if there exists x0 in S such that for all x in S the line segment from x0 to x is in S.
