English Abstract
Extrasolar planets are planets orbiting around star(s) outside the solar system.
Their numbers reached 473 planets till July 2010.
The history of Extrasolar planets research belong to a long time since the early of 1900’s.
During that time many discoveries have been appeared, but the real discovery came in 1995 when the first Extrasolar planet was discovered orbiting around 51 Pegasi star.
Radial velocity technique is considered as one of the most important methods for detecting Extrasolar planets, which was used in this research.
The interdependent techniques in Saint Mary Observatory in Canada were used in this research, which helped gaining an astronomic scientific knowledge to calculate the mass of planet that needed to prove its existence around a star.
By taking specific date observations and radial velocity observations for the star, results for the seven stars chosen for this purpose were reached and from several parameters the mass was calculated.
Two stars were unconfirmed its discovery, while the rest five stars were confirmed.
The results obtained for confirmed stars are found in a good agreement with the published results, while the unconfirmed stars’ results there were diverging in the calculated results.
That diverging is due to the modicums in the requisite observational data.
Estimating the mass of planet will help the astronomers to know whether the companion to the star is a planet or a dim star that can’t be seen.
Therefore this will prove the existence or the absence of the planet around a star.
