Exoplanet discovery has increased rapidly in past 20 years. Until April 22nd, 2014, <br />
<br />
<br />
<br />
<br />
there was 1,783 exoplanets have been confirmed (exoplanet.eu). Of the 1,783 <br />
<br />
<br />
<br />
<br />
exoplanets there are only less than 10 terrestrial exoplanet. This is important <br />
<br />
<br />
<br />
<br />
discovery for Astrobiology, the search for possibility of life in other planets. One <br />
<br />
<br />
<br />
<br />
way to search for signs of life is through biomarker observation in the exoplanet’s <br />
<br />
<br />
<br />
<br />
atmosphere. <br />
<br />
<br />
<br />
<br />
Until now, the Earth is the only planet that can be used as an example to search <br />
<br />
<br />
<br />
<br />
for life on other planets. To get a realistic model of Earth’s atmosphere, we have <br />
<br />
<br />
<br />
<br />
to study the radiative-convective and photochemical process. After the model of <br />
<br />
<br />
<br />
<br />
the Earth's atmosphere is made succesfully, the next step is to modelling the <br />
<br />
<br />
<br />
<br />
exoplanet’s atmosphere. In this final project, modelling is done by using a planet <br />
<br />
<br />
<br />
<br />
that has the same characteristics as the Earth, but it has a solar-like parent star. All <br />
<br />
<br />
<br />
<br />
data of pressure, temperature, and molecule parameter for each atmosphere’s <br />
<br />
<br />
<br />
<br />
altitude was obtained from a program created by Kasting et al. Then all data <br />
<br />
<br />
<br />
<br />
entered into the Line By Line Radiative Transfer Model (LBLRTM) program to <br />
<br />
<br />
<br />
<br />
be processed as a spectrum. <br />
<br />
<br />
<br />
<br />
Information obtained from that modelling shows that the profile of the atmosphere <br />
<br />
<br />
<br />
<br />
is strongly influenced by the flux of the parent star and the abundance of the <br />
<br />
<br />
<br />
<br />
molecules in the atmosphere. While the spectrum data can detect absorption of <br />
<br />
<br />
<br />
<br />
several molecules that can be used as biomarkers. |
