The Abundances of Helium, Magnesium and Phosphorus in the Atmosphere of HD144844.

MONIER R.

Abstract (from CDS):

Abundances of helium and magnesium are derived in LTE for the B9 Mn P Ga star HD 144844 using the group of He I lines near 4470.40 Å and the Mg II triplet at 4481.22 Å. Both elements are found to be very underabundant, about 2% of the solar helium and magnesium abundances. The profile of the Mg II line at 4481.22 Å clearly shows two components and confirms that this star is a double-lined spectroscopic binary. The synthesis of three P II lines at 6024.18, 6034.04 and 6043.88 Å yields phosphorus abundances from 150 up to 200 times the solar phosphorus abundance. A NLTE synthesis is necessary to derive more accurate abundances.
