In the last two decades, thousands of exoplanets have been found by using <br /> <br /> <br /> <br /> <br /> appropriate detection techniques. There is only a few terrestrial planet among them. <br /> <br /> <br /> <br /> <br /> It is very hard to find habitable terrestrial exoplanets because they have small size. <br /> <br /> <br /> <br /> <br /> By detecting biomarkers in their atmosphere, we can find them. Hence, the <br /> <br /> <br /> <br /> <br /> information about their atmospheric composition and temperature are very <br /> <br /> <br /> <br /> <br /> important. The informations can be obtained by simulating their atmospheric <br /> <br /> <br /> <br /> <br /> spectra. <br /> <br /> <br /> <br /> <br /> A fundamental aspect of planetary atmospheres is vertical thermal structure. This <br /> <br /> <br /> <br /> <br /> structure is the result of the various processes that occur in atmosphere. A onedimensional <br /> <br /> <br /> <br /> <br /> (vertical) model can provide a reasonable estimate of a planet’s globalmean <br /> <br /> <br /> <br /> <br /> temperature profile. It also can provide insights into the physics behind the <br /> <br /> <br /> <br /> <br /> thermal profile. <br /> <br /> <br /> <br /> <br /> In this Final Project, we are simulating atmospheric spectra for terrestrial planets <br /> <br /> <br /> <br /> <br /> around M dwarf star. Pressure, temperature, and molecular mixing ratio data were <br /> <br /> <br /> <br /> <br /> obtained by using Kasting’s program. This data will be used as the input for <br /> <br /> <br /> <br /> <br /> LBLRTM (Line-By-Line Radiative Model). LBLRTM will generate the spectra of <br /> <br /> <br /> <br /> <br /> planetary atmosphere. <br /> <br /> <br /> <br /> <br /> Simulation showed that the flux of the host star and molecular mixing ratio strongly <br /> <br /> <br /> <br /> <br /> affect thermal and mixing ratios profile of planetary atmospheres. The exoplanet’s <br /> <br /> <br /> <br /> <br /> atmospheres spectra showed that there were absorptions of biomarkers.
