| Summary: | 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. |
