Discovery of the binary nature of the magnetospheric B-type star Oph A
M. E. Shultz, I. Berry, D. Bohlender +11
The nearby B-type star Oph A was recently identified as a rapidly rotating magnetic B-type star with variable radio and X-ray emission consistent with a magnetospheric origin.…
HD 34736: An intensely magnetised double-lined spectroscopic binary with rapidly-rotating chemically peculiar B-type components
E. Semenko, O. Kochukhov, Z. Mikulášek +21
We report the results of a comprehensive study of the spectroscopic binary (SB2) system HD 34736 hosting two chemically peculiar (CP) late B-type stars. Using new and archival obse…
Spin-down and reduced mass loss in early-type stars with large-scale magnetic fields
Z. Keszthelyi, A. de Koter, Y. Götberg +12
Magnetism can greatly impact the evolution of stars. In some stars with OBA spectral types there is direct evidence via the Zeeman effect for stable, large-scale magnetospheres, wh…
The effects of surface fossil magnetic fields on massive star evolution: IV. Grids of models at Solar, LMC, and SMC metallicities
Z. Keszthelyi, A. de Koter, Y. Götberg +12
Magnetic fields can drastically change predictions of evolutionary models of massive stars via mass-loss quenching, magnetic braking, and efficient angular momentum transport, whic…
Testing a scaling relation between coherent radio emission and physical parameters of hot magnetic stars
Barnali Das, Poonam Chandra, Matt E. Shultz +4
Coherent radio emission via electron cyclotron maser emission (ECME) from hot magnetic stars was discovered more than two decades ago, but the physical conditions that make the gen…
Centrifugal breakout reconnection as the electron acceleration mechanism powering the radio magnetospheres of early-type stars
Stanley P Owocki, Matt E. Shultz, Asif ud-Doula +3
Magnetic B-stars often exhibit circularly polarized radio emission thought to arise from gyrosynchrotron emission by energetic electrons trapped in the circumstellar magnetosphere.…
