Chemical spots and their dynamical evolution on HgMn stars
Heidi Korhonen, Swetlana Hubrig, Maryline Briquet +2
Our recent studies of late B-type stars with HgMn peculiarity revealed for the first time the presence of fast dynamical evolution of chemical spots on their surfaces. These observ…
A multispectral view of the periodic events in eta Carinae
A. Damineli, D. J. Hillier, M. F. Corcoran +13
A full description of the 5.5-yr low excitation events in Eta Carinae is presented. We show that they are not as simple and brief as previously thought, but a combination of two co…
High resolution spectroscopy of HgMn stars: a time of surprises
S. Hubrig, C. R. Cowley, F. Gonzalez +1
We present the results of a high spectral resolution study of a few spectroscopic binaries with HgMn primary stars. We detect for the first time in the spectra of HgMn stars that f…
A study of the magnetic helium variable emission-line star HD 125823
S. Hubrig, N. Nesvacil, F. Gonzalez +2
The 5.9 M_sun star HD 125823 is a striking helium variable with a period of 8.82 d, ranging in helium spectral type from He-strong B2 to He-weak B8. For the first time we present h…
