[4] Global climate models of the planet indicate it has a very metal-rich atmosphere, with clouds made of silicate likely being present.
[2] Because of this, LTT 9779 b has been extensively studied by many space telescopes including Hubble and James Webb.
A study using JWST NIRISS found highly reflective white clouds on the western dayside of LTT 9779b.
The researchers suggest an eastwards equatorial jet, leading to a colder western dayside, allowing the formation of silicate clouds.
The study also detected water vapor in the atmosphere in the form of a dip at 1.4 μm.
