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…

Discovery of Magnetospheric Interactions in the Doubly-Magnetic Hot Binary Lupi

Ayan Biswas, Barnali Das, Poonam Chandra +6

Magnetic fields are extremely rare in close, hot binaries, with only 1.5\% of such systems known to contain a magnetic star. The eccentric Lupi system stands out in this popula…

Discovery of extraordinary X-ray emission from magnetospheric interaction in the unique binary stellar system Lupi

B. Das, V. Petit, Y. Nazé +12

We report detailed X-ray observations of the unique binary system Lupi, the only known short-period binary consisting of two magnetic early-type stars. The components have comp…

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…
