** Field(s) of activity for the internship**-
-** Topic of the internship: Exploring the data reduction pipeline for the Ariel exoplanet mission**-For the detailed topic descriptions please go to this web page:

Ariel is an upcoming ESA exoplanet mission, designed to perform a large survey of diverse exoplanets (goal >1000 planets observed) and to characterise their atmospheres during the nominal four-year mission. The telescope will observe each planet during multiple transits of and/or eclipses by its host star: during a transit, a fraction of the starlight is blocked by the planet and an even smaller fraction is filtered through the planet’s atmosphere; during an eclipse, the reflected and/or emitted light of the dayside of the planet’s atmosphere is blocked by the star.



Both types of observations can be utilized to deduce the composition of the planet’s atmosphere by analysing the obtained transit/eclipse spectra.-
-Your goal is to explore and assess the AMC-developed pipeline within the SOC environment, using both simulated data and ground-based test datasets. The selected intern will become familiar with the Ariel pipeline’s structure and algorithms and will have the opportunity to directly compare its performance and methodology to those of JWST. By offering feedback on pipeline development and deployment, you will contribute valuable insights for the Ariel mission, while also gaining a deeper understanding of ESA as an international organisation and about ESAC’s science operations in particular.-
