Spatially resolved centrifugal magnetosphere caught in motion around the secondary component of Oph A
R. Klement, M. E. Shultz, Th. Rivinius
The recently discovered spectroscopic binary Oph A is a rare magnetic hot binary system composed of two early B-type stars, comprising a non-magnetic primary (Aa) and a slightl…

Discovery of Main-sequence Radio Pulse emitters from widefield sky surveys
Barnali Das, Matt E. Shultz, Joshua Pritchard +6
Magnetic AB stars are known to produce periodic radio pulses by the electron cyclotron maser emission (ECME) mechanism. Only 19 such stars, known as 'Main-sequence Radio Pulse emit…

VAST-MeMeS: Characterising non-thermal radio emission from magnetic massive stars using the Australian SKA Pathfinder
Barnali Das, Laura N. Driessen, Matt E. Shultz +7
Magnetic massive stars are stars of spectral types O, B and A that harbour kG strength (mostly dipolar) surface magnetic fields. Their non-thermal radio emission has been de…
