[7] As is thought to be the case with most roAp stars, it has an overabundance of rare-earth elements as well as chromium and cobalt, solar-like levels of iron and nickel, and deficiencies in carbon and oxygen.

The strength and orientation of the magnetic field is strongly correlated with the layer of the atmosphere specific elements land in.

[13] Oscillations of the star were first discovered in 1987, with three distinct frequencies that each correspond to periods between 8.8 and 9.1 minutes and have low amplitudes between 0.25 and 0.49 millimagnitudes.

[15] In 2003, the pulsations were further resolved into standing and travelling waves in the stellar atmosphere utilizing the VLT, making HD 166473 the first star other than the Sun for such observations to be conducted.

[16] In 2020, the rotation period of the star was determined to be 3,836 days (10.50 years), making it only the fourth ever Ap star with a rotational period exceeding ten years whose magnetic field has been observed for an entire cycle or more.
