Evidence for neutron capture in heavy-metal hot subdwarfs: Far-UV spectroscopy of EC22536-5304 and LSIV-14 116
M. Dorsch, C. S. Jeffery, J. Deprince +8
Most hot subdwarfs (sdO/B) are low-mass core-helium-burning stars formed through binary interaction. A subgroup of intermediate He-rich sdOBs shows extreme heavy-metal (Z>30) enric…

Discovery of three magnetic helium-rich hot subdwarfs with SALT
M. Dorsch, C. S. Jeffery, A. Philip Monai +6
Magnetic fields with strengths ranging from 300 to 500 kG have recently been discovered in a group of four extremely similar helium-enriched hot subdwarf (He-sdO) stars. Besides th…
