Series: Planetary and exoplanetary Lunch Seminar (PALS)
Date: Monday 12-Feb-2024

Speaker: Vincent Kofman (NASA GSFC)
Title: Observables of 3 dimensional effects in direct imaging of exoplanets

Abstract: In this talk, I will discuss our recent results investigating the detectability of 3 dimensional effects in exoplanet observations. For this work, we used the Planetary Spectrum Generator, and its GlobES module, which interfaces with global circulation models. Two results are presented. In the first case, we demonstrate the use of the tool and showcase the differences between the 1D and 3D simulations of tidally locked Trappist 1b. Next, I will present our hyper-realistic models of the Earth and the investigation of the detectability of molecular species in the atmosphere. For this work we used a detailed noise models simulating space-based direct imaging concept telescopes (LUVOIR, HWO, HabEx). We show that the addition of clouds enhances the detectability of O2, H2O and O3 in almost all cases.

If you have any questions, contact the PALS hosts: Jacob Kloos (small bodies) and Matt Nixon (exoplanets).
