Binary Star System: Alpha Centauri B

According to the article, in 2012, astronomers have found a binary star system, which they named Alpha Centauri, that includes a star named Alpha Centauri B being orbited by the planet, Alpha Centauri Bb, by using the radial velocity method. To clarify on the radial velocity method, a planet may possibly be found by seeing the star wobble, which may most likely happen due to the gravitational pull of the planet. Astronomers also add that the newly found planet is 4.3 light years away from Earth, rocky, and slightly larger than Earth. Because several scientist later questioned the existence of the planet in 2013, Brice Oliver Demory and his team of colleagues at the University of Cambridge have soon studied Alpha Centauri B using the Hubble
For example, in 2012, astronomers have found Alpha Centauri B, a star that may have an orbiting planet named Alpha Centauri B. Thus, Demory and his team have studied the star, Alpha Centauri B, to see the supposed planet, Alpha Centauri Bb using the transit method in 2013 and 2014 for a total of 40 hours. After making the conclusion that there may actually be two planets orbiting Alpha Centauri B, there are debates among scientists to further continue studying Alpha Centauri, the binary star system where Alpha Centauri B and the other supposed two planets are located, to find any more planets that are hospitable to life. This shows the type of science the topic of this article falls under is Astronomy, the study of the universe and space, because the article covers the debated possibility of other planets hosting life like Earth. So since the topic is greatly involved with planets and space, the topic easily falls into the category of Astronomy, and Planetology, the study of planets, moons, and planetary systems, in particular. In addition, Demory study of planets possibly orbiting the star, Alpha Centauri B, further classifies the topic from Planetology to Exoplanetology because, in other words, Demory and his team are studying the possibility of an exoplanet since Alpha Centauri Bb orbiting a star other than the Sun, Alpha Centauri, makes it one. In conclusion, Exoplanetology is what the article of the topic falls
