Scientific paper

After a serendipitious discovery that HD 143418 is a light variable, we analyzed numerous UBV observations and Hipparcos Hp magnitudes transformed to Johnson V to find out whether the object is a very unusual spectroscopic binary.
Initial reductions of new photometry were carried out with the HEC22 program, while the new spectra were reduced in the IRAF and SPEFO programs. Orbital elements were derived with the FOTEL program, the KOREL disentangling was applied, and period searches were carried out using phase dispersion minimalization technique and the program PERIOD04. Final modeling of radial-velocity and light variations was carried out in PHOEBE.
