Gallium abundances in mercury-manganese stars
M. M. Dworetsky, C. M. Jomaron, C. A. Smith
There is a widespread assertion in the literature that the optical Ga lines give much higher abundances than the UV lines. We have determined Ga abundances in HgMn stars taking the…

Mercury and platinum abundances in mercury-manganese stars
C. M. Jomaron, M. M. Dworetsky, D. A. Bohlender
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 i…
