Oliver Herbort

Oliver Herbort : Postdoc

Oliver Herbort is working as an Ariel fellow PostDoc at the University of Vienna. His work is focussing on atmospheres of rocky exoplanets. Focussing on how the surface conditions of rocky exoplanets can be constrained by future observations. Therefore he is investigating atmospheric compositions based on different elemental compositions and the stability with respect to atmospheric loss and photochemistry.
One of his main interests is the habitability of exoplanets.
