EC 19529-4430: SALT identifies the most carbon- and metal-poor extreme helium star
Simon Jeffery, Laura Scott, Asish Philip Monai +2
EC 19529-4430 was identified as a helium-rich star in the Edinburgh-Cape Survey of faint-blue objects and subsequently resolved as a metal-poor extreme helium (EHe) star in the SAL…
Spectroscopic analysis of BPS CS 22940-0009: connecting evolved helium stars
E. J. Snowdon, L. J. A. Scott, C. S. Jeffery +1
BPS CS 22940-0009 is a helium-rich B-star that shares characteristics with both helium-rich B subdwarfs and extreme helium stars. The optical spectrum of BPS CS 22940-0009 has been…
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…
