Bizarre alien planet has layered atmosphere of vaporized metals

WASP-189 b properties and some info I calculated for this hot jupiter. Reference paper, Titanium oxide and chemical inhomogeneity in the atmosphere of the exoplanet WASP-189 b,, 27-Jan-2022. "...Here we report the unambiguous detection of TiO in the ultra-hot Jupiter WASP-189 b using high-resolution transmission spectroscopy."

My observation. WASP-189 b is listed with properties,

Plugging mass properties and others into my astronomy spreadsheet, orbital period or P = 3.0187E+00 day. The site shows 2.724 day period. In One billion years, this exoplanet could complete 1.2099E+11 or 120.99 billion revolutions around the host star (compared to Mercury, a bit more than 4 billion around the Sun). However, the star is listed as 0.855 Gyr old. The host star is 1.887 Msun and the exoplanet 1.99 Mjup with 1.619 Rjup radii.

Finding and identifying TiO in the atmosphere is important as atmosphere composition studies continue among the zoo of exoplanets reported today.
