Spectral analysis of four surprisingly similar hot hydrogen-rich subdwarf O stars

Spectral analysis of four surprisingly similar hot hydrogen-rich subdwarf O stars

Context. Post-extreme horizontal branch stars (post-EHB) are helium-shell burning objects evolving away from the EHB and contracting directly towards the white dwarf regime. While the stars forming the EHB have been extensively studied in the past, their hotter and more evolved progeny are not so we...
