The SALT survey of helium-rich hot subdwarfs: unsupervised classification and kinematic analysis
Asish Philip Monai, C. Simon Jeffery
Hydrogen-deficient stars form sequences across the HR diagram from cool R CrB stars to helium-rich hot subdwarfs and PG1159 stars, tracing multiple evolution pathways. The Southern…
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 distribution, kinematics and luminosities of extreme helium stars as probes of their origin and evolution
A. Philip Monai, P. Martin, C. S. Jeffery
Hydrogen deficient stars include the cool R CrB variable (RCBs) and hydrogen-deficient carbon (HdCs) giants through extreme helium stars (EHes) to the very hot helium-rich subdwarf…
