[2] Aside from periodic dimming caused by the transiting planet, the star experiences regular oscillations in brightness by a few thousandths of a magnitude.

[3] The nature of the luminosity fluctuations, namely the period and amplitude, along with the star's position within the instability strip in the Hertzsprung–Russell diagram implies that WASP-178 may be a Delta Scuti variable.

[2] In 2019, two teams, part of the WASP and KELT planet surveys respectively, independently reported the discovery of an exoplanet orbiting the star using the transit method.

[2][3] The planet was revealed to be an ultra-hot Jupiter revolving around the star every 3.3 days a mere 0.0558 AU (8,350,000 km) away, heating its surface up to a white-hot 2,470 K (2,200 °C; 3,990 °F).

[12] Silicon monoxide in particular was reported to have been discovered on WASP-178b in 2022, the first time the compound was detected in an exoplanet, but consistent with theoretical models on silicate minerals at high temperatures.
