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…
Kinematics of Subluminous O and B Stars by Surface Helium Abundance
P. Martin, C. S. Jeffery, Naslim N. +1
The majority of hot subdwarf stars are low-mass core-helium-burning stars. Their atmospheres are generally helium deficient; however a minority have extremely helium-rich surfaces.…
Discovery of a variable lead-rich hot subdwarf: UVO 0825+15
C. S. Jeffery, A. S. Baran, N. T. Behara +8
UVO0825+15 is a hot bright helium-rich subdwarf which lies in {\it K2} Field 5 and in a sample of intermediate helium-rich subdwarfs observed with {\it Subaru/HDS}. The {\it K2} li…
