DESCRIPTION:Hot subdwarfs are variously associated with the extreme horizo
 ntal branch and helium main-sequence\, as well as other low-mass stars evo
 lving to become white dwarfs. About 10% have partially or extremely helium
 -rich surfaces\, with highly heterogeneous properties. Using the Southern 
 African Large Telescope\, a spectroscopic survey was begun to search for a
 nd analyse new members of various subclasses. With over 500 stars observed
  to date\, we have discovered extreme helium stars\, heavy-metal subdwarfs
 \, super-hot pre-white dwarfs\, a planetary nebula\, a compact binary\, an
 d magnetic subdwarfs.
