The IACOB project XV. Updated calibrations of fundamental parameters of Galactic O-type stars
G. Holgado, S. Simón-DÃaz, A. Herrero
Modern spectroscopic surveys combined with Gaia distances are enabling reliable estimates of fundamental parameters for hundreds of Galactic O-type stars and the full range of spec…
An observational study of rotation and binarity of Galactic O-type runaway stars
M. Carretero-Castrillo, M. Ribó, J. M. Paredes +3
Gaia DR3 data have revealed new massive runaway stars, while spectroscopic surveys enable detailed characterization. The relative contributions of binary supernova (BSS) and dynami…
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…
Large-scale variability in macroturbulence driven by pulsations in the rapidly rotating massive star Zeta Oph from high-cadence ESPRESSO spectroscopy and TESS photometry
A. J. Kalita, D. M. Bowman, M. Abdul-Masih +1
Despite their importance, the dynamical properties of massive stars remain poorly understood. Rotation is a key driver of internal mixing and angular momentum transport, significan…
NGC 663 as a laboratory for massive star evolution
Amparo Marco, Ignacio Negueruela, Norberto Castro +1
Massive young clusters with rich populations of high-mass stars are ideal laboratories to explore their evolutionary paths. Despite being the most prominent cluster in the Perseus-…
