| | Alpha Andromedae abstract |
| | The variability of the Hg II 3984 line in the primary of the binary star alpha And was discovered through the examination of high dispersion spectra with S/N ratios greater than 500. | | | If the surface mercury distribution exhibits long term stability, then it is likely a weak magnetic field operates in its atmosphere, but if changes are observed in the line profile over a period of a few years, these would constitute direct evidence for diffusion. | | | This first definitively identified spectrum variation in any Mercury-Manganese star is not due to the orbital motion of the companion. |
