the visible component is a supergiant star that pulsates between spectral types f5ib and g0p. it is a small amplitude classical cepheid variable with an apparent magnitude ranges from 5.34 down to 5.58 over a period of 3.3428 days. on the hertzsprung–russell diagram of temperature versus luminosity, it is located near the blue (hotter) edge of the cepheid instability strip. models indicate the cepheid region is relatively small in this star, so there are no shock waves produced as a result of the instability.
