Discoveries of Helium Stars
In 2011, GALEX J184559.8−413827 (also known as J1845−4138) was labeled a "hot subdwarf." This means that GALEX J184559.8-413827 is characterized with being hotter and larger than the sun, while also being completely devoid of hydrogen. From these classifications, this hot subdwarf is considered to be a extreme helium star. In South Africa, the Southern Africa Large Telescope (SALT) has been monitoring this massive helium star's high-resolution spectrum.[1]
A Hypervelocity star (HVSs) called US 708, HVS 2 has been labeled a helium star. Being the most fast rotator, it is thought to be a remnant of a thermonuclear supernova.[2]
