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…
Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign
T. Shenar, J. Bodensteiner, M. Abdul-Masih +73
The BLOeM campaign presents the first large‑scale spectroscopic survey of 929 massive stars in the Small Magellanic Cloud, revealing a high intrinsic binary fraction (>70%) among m…
SpecFANN: Spectral Fitting via Artificial Neural Networks I. A deep learning based fastwind emulator and fitting suite
M. Abdul-Masih, C. Hawcroft, T. Lechien +14
The importance of massive stars cannot be overstated: they are powerful probes of the early universe, play a vital role in the chemical and mechanical evolution of their host envir…
K 1-6 is a photoionised ISM nebula shaped by a fast-moving hot white dwarf in a triple system
Jaroslav Merc, David Jones, Ana Escorza +22
The study shows that nebula K 1‑6 is not a planetary nebula but interstellar gas photoionised by an evolved hot white dwarf, and that its central star is a hierarchical triple syst…
Symbiotic binaries in the Gaia data. II. Symbiotic candidates from general variability classification in DR3
Jaroslav Merc, Lionel Mulato, Joanna MikoÅajewska +7
The paper evaluates how well Gaia DR3’s general variability classification identifies symbiotic binaries, finds that many new candidates are actually pulsating red giants, and uses…
Physics of Eclipsing Binaries. VI. Hot, compact stars
David Jones, Nicole Reindl, Kyle Conroy +9
Models of eclipsing binaries require the assignment of appropriate emergent intensities to the surface elements of the binary components. For distance-dependent modelling of flux-c…
