... AR Aur is the only eclipsing binary known to contain a HgMn star, making it an ideal case for a detailed study of the HgMn phenomenon. HgMn stars are a poorly understood class of chemically peculiar stars, which have traditionally been thought not to possess significant magnetic fields. However, the recent discovery of line profile variability in some HgMn stars, apparently attributable to surface abundance patches, has brought this belief into question. ...

... Journal: 1973, Astron Zh., ... The isotopic shifts of helium spectral lines have been measured for four high velocity OB-stars and one standard star. The spectrograms were secured at 2.6 m reflector of the Grimean observatory, dispersion beging 8 / mm . All five stars did not show the systematic isotopic shifts. But three lines of 53 Ari have shown shifts which are in agreement with theoretical ones, but other helium lines did not show such shifts. ...
