An exoplanet is hot enough to turn metal into vapor. It is known as KELT-9b, a gas giant located 650 light-years from Earth that has atmospheric temperatures so hot – over 4,000 °C (7,232 °F) – it can vaporize iron and titanium.
Observing unresolved disks at submm/cm wavelengths requires an accurate emission model of the host star in order to separate the stellar and disk flux contributions. It is difficult (and in some cases impossible) to test these models for stellar types other than the Sun.#IAU2018
