However, detecting biosignatures on rocky exoplanets within the habitable zone of their stars poses significant challenges due to the low signal-to-noise ratio (SNR) resulting from the smaller relative...

... (HRTS) is a powerful tool for exoplanet atmospheric characterization. High spectral resolution allows us to resolve and detect individual atomic and molecular species without the help of atmospheric retrieval models (Snellen et al. 2008 ). It is also possible to detect signatures of global circulation...

Melt compositions, in turn, reflect (i) the bulk composition of the planet and (ii) the pressure and temperature at its surface, serving as an indirect window into the interior structure and composition of such exoplanets as well as possible markers to determine formation location...
