Revealing the nature of HD157087

Khalack, Viktor

The new spectropolarimetric spectra of HD 157087 obtained recently with ESPaDOnS at CFHT are analysed to verify the nature of this object. The abundance analysis also reveals evidence of a significant abundance increase towards the deeper atmospheric layers for several chemical elements. Together with the found enhanced abundance of Ca and Sc this fact contradicts the classification of HD 157087 as a marginal Am star.
