On January 15, 2010, a team of astronomers released the results of computer simulations indicating that kilometer-size planetesimals can form and accrete into rocky Earth-size planets around Alpha Centauri B despite gravitational perturbations from Alpha Centauri A. The binary system, however, does not offer "favorable" conditions for the formation of gas giants, like Jupiter and Saturn. Star B was chosen for analysis because efforts are underway to detect of an Earth-like planet in or near its habitable zone (between 0.5 and 0.9 AU) using available technology
2010年,天文学家公布了利用计算机模拟的南门二附近的行星形成情况,指出:尽管会受到南门二A引力的摄动,在南门二B的宜居带或以内仍能经由吸积而形成地球尺寸的行星,不过电脑模拟结果并不支持诸如木星、土星般大小的类木行星形成(原因显而易见),同时提到科学家在为发现环绕南门二B的类地行星而努力
结合今日之探测结果来看,当初的电脑模拟还是很靠谱的 |
