Oral title: 6 years of TRAPPIST comet survey

Oral abstract: TRAPPIST is a 60-cm robotic telescope in La Silla, equipped with a set of narrow band cometary filters 
designed to isolated the emission of OH, NH, CN, C2, and C3, as well as several zones of the dust reflected continuum, 
in the coma of comets. Since the installation of the telescope in 2010, we gathered a very high quality and homogeneous 
data set of more than 35 bright comets observed with one single telescope and instrument. Our data set is composed of 
more than 15000 images and allows us to study the general evolution of cometary activity and coma composition along 
the orbit of comets. We will present the results of our survey, trying to answer the following questions: Can we define 
classes of comets based on their composition? Are composition differences between comets of pristine of evolutionary 
nature? Is the composition of comets linked to their place of formation in the solar system?
