Predicting Stellar Parameters of Massive Stars from Light Curves with Machine Learning
Rachel C. Zhang, Kaze W. K. Wong, Gonzalo Holgado +1
High-resolution spectroscopic measurements of OB stars are important for understanding processes like stellar evolution, but require labor-intensive observations. In contrast, phot…

A magnetic field detection in the massive O-type bright giant 63 Oph
James A. Barron, Gregg A. Wade, Gonzalo Holgado +1
Surface magnetic fields are detected in less than of the massive O-type star population and even less frequently among `old' massive stars approaching the terminal-age main…

A Non-Stop Aurora? The Intriguing Radio Emission from the Rapidly Rotating Magnetic Massive Star HR 5907
Ayan Biswas, Barnali Das, James A. Barron +2
HR 5907 (HD 142184) stands out among magnetic OB stars for its rapid rotation, exceptionally hard X-ray emission, and strong magnetic field. High-frequency (>5 GHz) radio emission…
