CHAMELEON: Virtual Laboratories for Exoplanets and Planet-Forming Disks.

Virtual laboratories play a key role in
simulating yet unexplored
physico-chemical environments. Retrieving (from
data), predicting (from detailed models) and
thereby understanding the link between the
chemical composition of planet-forming disks and
exoplanet atmospheres is challenging.

an overview of the research

We present results that were achieved
within the CHAMELEON MC ITN which have been
published in more than  100 papers so far. This
talks aspires to showcase not only past results
but also new research avenues that CHAMELEON has
enabled.  Achievements range from new insight
into small-scale process like the effect of high-
energy radiation on cloud particles and the
formation metal-oxide clusters as precursors for
cloud formation, the detection unexpectedly high
C/O ratios in the inner parts of plant-forming
disks but also the development of new models for
planetary atmospheres in 1D and 3D, charged dust
in planet forming disks, and machine learning
frameworks. CHAMELEON virtual laboratories are
used to interpret data from space missions like
JWST and CHEOPS, and to prepare new missions like
PLATO, Ariel and the HWO.
