Abstract
For two integers and , the -extra -component connectivity of a graph , denoted by , is defined as the minimum number of vertices whose removal produces a disconnected graph with at least components, where each component contains at least vertices. Let represent the set of graphs of order with minimum degree and -extra -component connectivity . Hu, Lin, and Zhang [\textit{Discrete Math.} \textbf{345} (2025) 114621] investigated the case when within , and characterized the corresponding extremal graphs that minimize the distance spectral radius. In this paper, we further explore the relevant extremal graphs in for .
