Its story

43 Cassiopeiae is a remarkable oddity: a chemically peculiar A0 star, rich in silicon and strontium, classed as an Alpha² Canum Venaticorum variable. Its intense magnetic field sorts elements into surface bands, and as it rotates it shows different chemical mixes. At 389 light-years, it drifts slightly around magnitude 5.57 inside Cassiopeia's W, a hidden jewel among the stars that trace the mythical queen.
