The Behavior of HgMn Stars in the Far-UV-Paper 26: HD 207857.

MONIER R.

Abstract (from CDS):

The analysis of two spectra of the Mn P Ga spectroscopic binary HD 207857 recorded by the SWP camera on board the International Ultraviolet Explorer reveals one instance of variation of the far-ultraviolet flux of this star over a time interval of about 10 months. The orbital period of this spectroscopic binary being 338.2 days, the observed increases of flux below 1800 Å could be due to the presence of a hot companion.
