Teleios (G305.4-2.2) -- the mystery of a perfectly shaped new Galactic supernova remnant
Miroslav D. Filipovic, Zachary J. Smeaton, Roland Kothes +35
We present the serendipitous radio-continuum discovery of a likely Galactic supernova remnant (SNR) G305.4-2.2. This object displays a remarkable circular symmetry in shape, making…

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…
