Astronomers Detect Titanium Oxide and Several Metals in Atmosphere of WASP-189b

The temperature of a planet’s environment decreases with growing altitude, until a shortwave absorber that causes a temperature inversion exists. Ozone performs this function within the Earth’s environment. In the atmospheres of extremely irradiated exoplanets, the shortwave absorbers are predicted to be titanium oxide and vanadium oxide. Using high-resolution transmission spectroscopy, astronomers have now detected […]
