The SALT survey of helium-rich hot subdwarfs: final sample and classification
C. Simon Jeffery, Matti Dorsch, Asish Philip Monai +3
A medium-resolution spectroscopic survey of helium-rich hot subdwarfs has been carried out using the Southern African Large Telescope (SALT). Objectives include the discovery of ex…
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…
The SALT survey of helium-rich hot subdwarfs: methods, classification, and coarse analysis
Simon Jeffery, Brent Miszalski, Edward Snowdon
A medium- and high-resolution spectroscopic survey of helium-rich hot subdwarfs is being carried out using the Southern African Large Telescope (SALT). Objectives include the disco…
EC 22536-5304: SALT identifies a new lead-rich intermediate helium subdwarf
C. Simon Jeffery, Brent Miszalski
SALT spectra of the helium-rich hot subdwarf EC22536-5304 show strong absorption lines of triply-ionized lead. Analysis of the HRS spectrum and a follow-up SALT/RSS spectrum show E…
