Modelling reﬂected polarized light from exoplanetary atmospheres
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
I present numerical simulations of intensity and degree of polarization of light reﬂected by Earth-like exoplanets. The results are presented as a function of wavelength, and for a few diﬀerent phase angles and a few diﬀerent points on the planet. At this stage the aim is to show the working code and test a few diﬀerent set ups of the star-planet system in order to ﬁnd preferable conﬁgurations for observations. Not surprisingly, phase angle 90◦ shows the largest degree of polarization. For beneﬁcial wavelength regions, visual light shows a larger overall degree of polarization, while NIR shows very clear absorption patterns in the degree of polarization, making detection of the atmospheric composition possible.
