Line list of HD 143418

Its light displays an orbital phase coupled variability with a peak-to-peak amplitude up to 0.04mag. The photometry available and new high dispersion spectra were investigated from a point of view of CP characteristics.

A series of high resolution high S/N coude spectra was acquired from which 25 weak to strong unblended lines of Fe I and II, Ti II, Cr II, Zr II, and Ba II were selected to study spectral line variability. Two Zeeman spectra were obtained to search for a possible magnetic field of the star, and one echelle spectrum in a wide spectral region was analysed for abundance determination by means of synthetic spectra. The photometric observations were subjected to a PCA disentangling of the complex photometric behaviour.
