How Do You Find an Exoplanet? (Princeton Frontiers in Physics)
外星人的世界一直是科幻小說的主角。但今天，由於現代天文儀器和許多進取的觀測天文學家的成就，我們的太陽系以外的行星（也稱為系外行星）的存在已經進入了科學事實的領域。隨著行星獵手發現越來越小，更像地球的世界，我們對宇宙的認識是永遠改變的......
你如何找到一個外行星？約翰•約翰遜（John Johnson）為您提供了一個內部人士對這個激動人心的尖端科學的看法，展示了天文學家如何檢測軌道行星的引力拖曳引起的恆星搖擺，行星超越恆星引起的輕微減弱以及彎曲時空中的星星和他們的行星，以及天文學家如何直接在明亮的中央恆星旁邊拍攝行星的照片。
你如何找到一個外行星？揭示了在太陽系外尋找生命的前景，新的觀察結果如何令人驚訝，表明我們可能不完全了解行星是如何形成的......
Alien worlds have long been a staple of science fiction. But today, thanks to modern astronomical instrumentation and the achievements of many enterprising observational astronomers, the existence of planets outside our solar system―also known as exoplanets―has moved into the realm of science fact. With planet hunters finding ever smaller, more Earth-like worlds, our understanding of the cosmos is forever changed, yet the question of how astronomers make these discoveries often goes unanswered.
How Do You Find an Exoplanet? is an authoritative primer on the four key techniques that today's planet hunters use to detect the feeble signals of planets orbiting distant stars. John Johnson provides you with an insider’s perspective on this exciting cutting-edge science, showing how astronomers detect the wobble of stars caused by the gravitational tug of an orbiting planet, the slight diminution of light caused by a planet eclipsing its star, and the bending of space-time by stars and their planets, and how astronomers even directly take pictures of planets next to their bright central stars.
Accessible to anyone with a basic foundation in college-level physics, How Do You Find an Exoplanet? sheds new light on the prospect of finding life outside our solar system, how surprising new observations suggest that we may not fully understand how planets form, and much more.
