About

B. N. Barlow is an astrophysicist specializing in the study of hot subdwarf B (sdB) stars, particularly their pulsational properties and binary interactions. Their major contributions center on the discovery and characterization of sdBV stars—pulsating subdwarfs that serve as natural laboratories for asteroseismology. Barlow led the discovery of large-amplitude oscillations in CS 1246 (2010, 25 citations), a landmark paper that identified this star as a new sdBV and provided critical multicolour photometry and time-resolved spectroscopy. Follow-up work (2017, 9 citations) used pulse timing measurements to reveal reflex motion from a low-mass M dwarf companion and a long-term period decrease, demonstrating the power of O-C diagrams in detecting substellar companions and evolutionary changes. Additional studies of EC 22221-3152 (2017, 4 citations) combined two-site photometry and spectroscopy to refine the pulsation spectrum of a rapidly pulsating sdB star. Barlow’s work has advanced our understanding of stellar evolution, binary dynamics, and the interior structure of extreme horizontal branch stars, with impact reflected in citations that continue to inform asteroseismic modeling and exoplanet searches around evolved stars.
