HgMn Stars as apparent X-ray emitters
S. Hubrig, W. Berghoefer, G. Mathys
In the ROSAT all-sky survey 11 HgMn stars were detected as soft X-ray emitters (Berghoefer, Schmitt & Cassinelli 1996). Prior to ROSAT, X-ray observations with the Einstein Observa…
Isotopic composition of Hg and Pt in slowly rotating HgMn stars
S. Hubrig, F. Castelli, G. Mathys
Preliminary results from a study of the isotopic compositions of the elements Hg and Pt in a number of HgMn stars are presented. This work represents an improvement over previous s…
Magnetic Bp and Ap stars in the H-R diagram
S. Hubrig, P. North, G. Mathys
The positions in the H-R diagram of strongly magnetic Ap and Bp stars are compared with those of normal main sequence stars of types B7 to F2, with a view to investigating possible…
HgMn stars: new insights
S. Hubrig
Recent results obtained by various authors on the properties of HgMn stars are reviewed. Substantial progress has been achieved in the study of abundances and isotopic anomalies. T…
