Let \((X_t)\) be a rotation invariant Feller process on the state space \(F\in\mathbb{R}^2\setminus\{0\}\) consisting of a finite number of rays, meeting at \(0\). The author studies a certain class of possible strong Markov extensions of \((X_t)\) to \(F\cup\{0\}\), given the corresponding radial extension to \(\{0,+\infty)\).
