About

J. B. Haislip is an observational astronomer whose research focuses on the pulsations and binary nature of hot subdwarf B (sdB) stars—evolved, compact objects that serve as natural laboratories for stellar astrophysics. Haislip’s work combines high-precision photometry and spectroscopy to probe the internal structure and orbital dynamics of these stars. In a landmark 2017 study on CS 1246, Haislip used pulse timing measurements to detect the reflex motion of a low-mass M dwarf companion and uncovered a long-term period decrease, providing critical insights into binary evolution and pulsational stability. This paper has garnered 9 citations, reflecting its importance in the field. Haislip also led a two-site photometric and spectroscopic campaign on the rapidly pulsating sdB star EC 22221-3152, using telescopes at the South African Astronomical Observatory and the PROMPT array at CTIO to resolve its complex pulsation spectrum. With 4 citations, this work demonstrates Haislip’s skill in coordinating multi-observatory efforts. Through these contributions, Haislip has advanced our understanding of sdB star interiors and the role of binarity in their evolution, making a lasting impact on stellar astrophysics.
