Kapteyn's star M0 greater than 1000 Kelvin subdwarf 13 light-years +242 km s^-1 CD -45 1841 A nearby high-velocity M0 subdwarf that is both the nearest halo star to the Sun and the nearest star that orbits the Galaxy backward. 1897 Jacobus Kapteyn

sdB 11000 to 28000 K blue-white He I subdwarf Subdwarf B star with very broad and shallow Balmer lines; fewer lines of the Balmer series are visible than for normal dwarfs.

sdO 35000 K very high blue-white He II rare 3 to 6 million years subdwarf Subdwarf O star showing few very broad and shallow Balmer lines and a very strong He II 4686 line.
