Scientific paper

Over the past few years a GTO team project has obtained extensive GHRS echelle observations of UV transitions of heavy elements in the Hg-Mn stars chi Lupi and Kappa Cancri. Isotopic anomalies, in which only the heaviest isotope of Hg, Pt and Tl is present, have been observed in chi Lupi, but are apparently absent in kappa Cancri. Kappa Cancri is distinguished from chi Lupi by both its higher effective temperature and its larger Mn abundance. To help constrain theoretical interpretations of the abundance and isotope anomalies, this program will observe the Hg-Mn star HR7775, which has the same effective temperature as chi-Lupi, but also has substantially higher Mn and Bi abundances. Observations will be obtained of the same Tl II line at 1909 A which was used to discover the Tl isotope anomaly in chi Lupi. Lines of Bi II, Sb II, Pd II, Au III, C I and S I will also be observed.
