A search for magnetic stars in late stages of stellar evolution
  Two types of stars are known to have strong, large scale magnetic fields: the main sequence Ap stars and the magnetic white dwarfs. This suggest that the former might be the progenitors of the latter. In order to test this idea, I have carried out a search for large scale magnetic fields in stars with evolutionary states which are intermediate, i.e. in Horizontal Branch stars and in hot subdwarfs.
