The symphony of pulsations and binarity among massive stars using HERMES spectroscopy and TESS photometry
K. Thomson-Paressant, D. M. Bowman, F. Nardini +16
A wide range of variability mechanisms exist among intermediate mass and massive stars, which are not yet fully understood. Using complementary data sources for a large population…

Asteroseismology of SPB stars: a comparison of forward asteroseismic modelling results from Kepler and TESS
L. J. A. Scott, D. M. Bowman
The slowly pulsating B (SPB) stars are a class of variable star with masses between about 3 and 8 M. Their gravity-mode pulsation frequencies are sensitive to the near-co…

New Level Resolved Ground and Excited State Pb III, IV, V & VI Photoionization Cross Sections for Heavy Metal Subdwarf Modeling
David J. Dougan, Matti Dorsch, Laura J. A. Scott +3
High abundances of various lead (Pb) species have been identified in the spectra of many Asymptotic Giant Branch (AGB) stars and O- and B-type subdwarfs (sdO/B). Additional atomic…
