Chronothesis : my thesis in 5 minutes/ is a competition involving the presentation of a thesis subject involving astronomy, astroparticles, astrophysics.
The thesis candidate must present their research subject in 5 minutes, in French, and in a straightforward way, to a group of visitors, schoolchildren and non-experts.
The overall winner was Océane Barraud, currently in her second year of thesis work at the LESIA, directed by Alain Doressoundiram (and co-directed by ESA’s Sébastien BESSE). The subject of her thesis is « The naure of the volcanic episodes on the surface of Mercury ».
Océane BarraudFollowing a first degree in terrestrial sciences (volcanology) and a master inPlanetary Sciences, Océane Barraud joined the planetology team of the Laboratory for space studies and astrophysical instrumentation.
Her work involves the study and quantification the volcanic episodes on planetary surfaces. The objective of this work is to constrain the physical properties (thermal conditions, magma composition...) of the planet during the early stages of its formation and during its evolution.
To do this, Océane Barraud is using observations made by NASA’s Messenger probe, in orbit around Mercury from 2011 to 2015.
Her cork could also be used to identify targets on the planetary surface for upcoming observations by the BepiColombo probe launched towards Mercury by the European Space Agency in October 2018.
