DESCRIPTION:Ultra-hot Jupiters (UHJs) have become prime targets for atmosph
 eric characterisation. Owing to their close-in orbits and the early spectra
 l types of their host stars\, these planets are unique laboratories for stu
 dying atmospheric physics and chemistry under extreme conditions. One of th
 e most compelling processes to investigate in these environments is atmosph
 eric escape\, which is thought to be a major driver of the long-term evolut
 ion of planetary atmospheres across a wide range of planets. Atmospheric ma
 ss loss is powered by heating processes that are strongly influenced by non
 -local thermodynamic equilibrium (NLTE) effects. I will show how NLTE proce
 sses shape the physical and chemical structure of UHJ atmospheres and discu
 ss the observational evidence supporting these results on the basis of mult
 iple datasets. To arrange a visit with the speaker during the visit\, pleas
