Context: .The chemically peculiar HgMn stars are a class of Bp stars which have historically been found to be both non-magnetic and non-variable. Remarkably, it has recently been demonstrated that the bright, well-studied HgMn star ? And exhibits clear Hg ii line profile variations indicative of a non-uniform surface distribution of this element. Aims: .With this work, we have conducted an extensive search for magnetic fields in the photosphere of ? And. Methods: .We have acquired new circular… Expand
