Transmission Spectroscopy
In an earlier post (exoplanet detection methods) I had explained the Radial Velocity method of finding an exoplanet. This particular method is possible only because of spectrographs like the HARPS and ESPRESSO. These spectra are then analyzed to find and identify a particular planet and it's atmosphere. Transmission spectroscopy is a technique used in astronomy to study the atmospheres of exoplanets, which are planets outside of our solar system. It involves measuring the amount of starlight that passes through the planet's atmosphere during a transit and analyzing the resulting spectrum to detect and characterize the molecular composition and physical properties of the atmosphere. Transmission spectroscopy is used to study exoplanet atmospheres and understand their physical and chemical properties. By detecting the absorption or emission lines of molecules in the atmosphere, astronomers can infer the temperature, pressure, composition, and structure of the atmosphere. Althoug...
