About

B. H. Dunlap is an observational astrophysicist specializing in the study of hot subdwarf B (sdB) stars, particularly their pulsational properties. Dunlap’s major contributions lie in the detection and characterization of rapidly oscillating sdB variables (sdBV), using multi-site photometry and time-resolved spectroscopy to probe the interiors of these evolved, compact stars. In the landmark 2010 study of CS 1246 (25 citations), Dunlap reported the discovery of a large-amplitude oscillation, providing critical data for asteroseismic modeling. This work, leveraging the unique capabilities of the PROMPT telescope array, established new constraints on the structure and evolution of extreme horizontal branch stars. A subsequent 2017 study of EC 22221-3152 (4 citations) extended this work with coordinated two-site observations from South Africa and Chile, demonstrating the power of global telescope networks for resolving pulsation modes. Dunlap’s research has advanced our understanding of stellar evolution in binary systems and the internal physics of post-red-giant stars, making important contributions to the field of compact pulsators.
