Xenon in Mercury-Manganese Stars (2008)
Dworetsky, M. M., Persaud, J. L., Patel, K.
Previous studies of elemental abundances in Mercury-Manganese (HgMn) stars have occasionally reported the presence of lines of the ionized rare noble gas Xe II, especially in a few of the hottest...
The Secondary Star of the HgMn Binary Phi Her (2006)
Dworetsky, M. M., Willatt, Rosemary
The binary nature of the bright (V = 4.2 mag) Mercury-Manganese star Phi Her has been known since 1976 and it was considered a low-amplitude single-lined SB. In a recent study we found evidence for...
Radiative accelerations on Ne in the atmospheres of late B stars (2002)
Radiative accelerations on Ne are calculated for the atmospheres of main sequence stars with 11000 < Teff < 15000 K, corresponding to the range of the HgMn stars. The calculations take into account...
Neon abundances in normal late-B and mercury-manganese stars (2000)
We make new Non-LTE calculations to deduce abundances of neon from visible-region echelle spectra of selected Ne I lines in 7 normal stars and 20 HgMn stars. We find that the best strong blend-free...

High-resolution spectra have been obtained for the regions of the five strongest optical lines of Pt II in the spectrum of the cool HgMn star HR 7775, which is one of the sharpest-lined HgMn stars...
Isotopic Pt II Abundances in the HgMn Star HR 7775 (1998)
D. A. Bohlender, M. M. Dworetsky, C. M. Jomaron
High-resolution spectra have been obtained for the regions of the five strongest optical lines of Pt II in the spectrum of the cool HgMn star HR 7775, which is one of the sharpest-lined HgMn stars...
Mercury and platinum abundances in mercury-manganese stars (1998)
Jomaron, C. M., Dworetsky, M. M., Bohlender, D. A.
We report new results for the elemental and isotopic abundances of the normally rare elements mercury and platinum in HgMn stars. Typical overabundances can be 4 dex or more. The isotopic patterns do...
