Proceedings of the MOBSTER-1 virtual conference held 12-17 July 2020

The scientific scope of the MOBSTER-1 conference included all astrophysical “themes” related to massive stars, with a specific focus on how they interplay with current research on the origin and impact of magnetic fields. This virtual conference focused on five themes that were identified as lying at the intersection between the science cases of the MOBSTER Collaboration and of the general massive/intermediate-mass star community.

Main scientific themes:

Binarity: e.g. binarity of massive stars in TESS data, the BinaMiCS project, tidally induced pulsations, etc.
Asteroseismology: e.g. asteroseismology of intermediate- (A) and high-mass (OB) stars, seismic diagnostics for (interior) magnetic fields, etc.
Magnetic characterisation: e.g. spectropolarimetry, photometric identification of magnetic stars, surveys of magnetic stars, magnetic stars across the HR diagram, spectroscopic characterisation of magnetic stars, etc.
Evolution: e.g. aspects of stellar evolution related to the other topics, origins of magnetism in massive stars, star formation, etc.
Rotation, winds & outflows: e.g. intrinsic variability of stellar winds (CIRs, DAC), spotted stars and rotational modulation, magnetospheres, etc.
