Show moren the James Webb Space Telescope and Extremely Large Telescopes era we expect to characterize a number of potentially habitable Earth-like exoplanets. However, the characterization of these worlds depends crucially on the accuracy of theoretical models. Validating these models against observations of planets with known properties will be key for the future characterization of terrestrial exoplanets. Due to its sensitivity to the micro- and macro-physical properties of an atmosphere, spectropolarimetry will be an important tool that in tandem with traditional flux-only observations will enhance the capabilities of characterizing Earth-like planets. In this presentation we benchmark two separate polarization-enabled radiative transfer codes against each other and against unique linear spectropolarimetric observations of the Earthshine (i.e., sunlight scattered by the dayside of the Earth and reflected back to the planet by the nightside of the Moon) that cover wavelengths from ~ 0.4 μm to ~ 2.3 μm. We find that the results from the two codes agree with each other but both underestimate the level of polarization of the Earthshine. We discuss how we plan to update the two codes to better fit the observations. We also report an interesting discrepancy between our models and the observed 1.27 μm O2 feature in the Earthshine, together with an analysis of potential methods for matching this feature and a discussion on the implications this has for future observations of habitable exoplanets.

Show moreStudies into the history of mate search show that important mate choice criteria vary through time, influenced by societal circumstances, whereas others seem to remain constant. Nowadays, online dating has become one of the most popularways to meet a partner, which changed the mate selection process because this computer-mediated communication facilitates selective self-presentation. Biographies of dating app profiles are space limited and often selfwritten, providing insight in what users find crucial to mention about themselves and their wishes for a future partner. Here we collected 300 biographies from three online dating platforms and coded them on four content themes: dating intention, personality and appearance of self vs. potential partner, and lifestyle.We present a preliminary comparison of these mate choice criteria between gender and age.
