In this paper, we generalize the notion of self-orthogonal codes to $ \sigma $-self-orthogonal codes over an arbitrary finite ring. Then, we study the $ \sigma $-self-orthogonality of constacyclic codes of length $ p^s $ over the finite commutative chain ring $ \mathbb F_{p^m} + u \mathbb F_{p^m} $, where $ p $ is a prime, $ u^2 = 0 $ and $ \sigma $ is an arbitrary ring automorphism of $ \mathbb F_{p^m} + u \mathbb F_{p^m} $. We characterize the structure of $ \sigma $-dual code of a $ \lambda $-constacyclic code of length $ p^s $ over $ \mathbb F_{p^m} + u \mathbb F_{p^m} $. Further, the necessary and sufficient conditions for a $ \lambda $-constacyclic code to be $ \sigma $-self-orthogonal are provided. In particular, we determine all $ \sigma $-self-dual constacyclic codes of length $ p^s $ over $ \mathbb F_{p^m} + u \mathbb F_{p^m} $. In the end of this paper, when $ p $ is an odd prime, we extend the results to constacyclic codes of length $ 2 p^s $.

Keywords: Constacyclic code, repeated-root code, $ \sigma $-self-orthogonal code, $ \sigma $-self-dual code, finite commutative chain ring.
