| Summary: | Since the first discovery in 1995, there are more than three thousand exoplanets (extrasolar planets) found today. Exoplanet detections have been conducted with various methods, including using radial velocity techniques which successfully made the first discovery of exoplanet (51 Peg b). This method contributes about 20% of total exoplanets confirmed until now and this number <br />
<br />
will be still increasing in the future. For that reason, radial velocity method is an important and prospective method to be discussed. Radial velocity method analyzes wobble motion of a star due to the presence of planetary companion and the corresponding radial velocity depends <br />
<br />
on various parameters. The changes in radial velocity can be analyzed using a simulation program that consider the object's characteristics and orientation of orbit. For the analysis, this final project is focused on radial velocity method for exoplanet dete tion, in luding simulation of exoplanets' radial velo ity data. It can be concluded that radial velocity method could provide a good constraint for <br />
<br />
various parameters such as minimum mass, eccentricity and argument of periastron. The basic principle of observation using this method as well as the best and succesful spectrographs in exoplanet observing programs are also discussed in this final project. From the discussion we concluded a suggestion for future exoplanet observation program in National Observatory using radial velocity <br />
<br />
method. |
