Hotter than Hell: Understanding Ultra-Hot Jupiters through transmission spectroscopy

Resumen

In the rapidly changing world of exoplanets, a new class of planets has emerged recently: the so called Ultra-Hot Jupiters, which have no analogue in our own solar system. Characterised by their short orbits and proximity to their host star, these worlds receive thousands of times the Earth’s insolation and have effective temperatures above 2000 K, making them intriguing candidates to study the most extreme atmospheric environments. A notable feature of these high temperatures is that the transmission spectra of these planets are rich in atomic metal lines, which provide new probes into the chemistry and dynamics of their atmospheres. I will highlight what we have recently learned about Ultra-Hot Jupiter atmospheres and focus on what knowledge can be derived directly from ground-based observations via transmission spectroscopy.
