Haze is common in Solar System atmospheres and is expected in exoplanet atmospheres as well. Many results hint toward the presence of such small particles at high altitudes in the atmosphere of those far worlds. In this presentation, we will explore photochemical haze and its impacts in hot-Jupiters atmospheres.
How haze affects the radiative transfer ?
How it may help in the formation of clouds ?
What are the effects of these processes on the observed transit spectra ?
We will answer those questions and see that, despite the high temperatures hot-Jupiters atmospheres exhibit, haze has found a way... Finally, we will talk about Titan and why haze (but not only) makes a new radiative transfer solver necessary for Titan PCM.
