英语翻译
If his team sees a companion object to a star in more than one NICMOS picture,and it appears to have moved along an orbit,follow-up observations will be made with ground-based telescopes.If they see something once but its brightness and separation from the star would be reasonable for a planet,they will also do follow-up observations with ground-based telescopes.
Taking the image of an exoplanet is not an easy task.Planets can be billions of times fainter than the star around which they orbit and are typically located at separations smaller than 1/2000th the angular size of the full moon from their star.The planet recovered in the NICMOS data is about 100,000 times fainter than the star when viewed in the near-infrared.
"Even when using the best telescopes available,with the best resolution,the light from the bright star spills out in the area where the much fainter planets are located,making them impossible to see.It is essential to subtract out this bright glare of stellar light from the image to see faint dots,i.e.,planets that could be hidden underneath," says Rene Doyon of the University of Montreal.
The stability of how light is scattered in the NICMOS camera,called the point spread function (PSF),is key for using Hubble images to recover planets.This technique works by taking images of different stars and combining them to create a PSF of a star that closely resembles the star that is being studied for planets.This requires a reasonably steady PSF because images of different stars are taken on different days.Atmospheric conditions would vary from day-to-day for ground-based telescopes,but not for a space telescope that enjoys unprecedented image stability over repeated visits to a target.

如果他的团队看到一个同伴的对象的一颗恒星在超过100 -图片,它似乎已经将沿轨道,随后他们将用望远镜。如果他们看到什么,但它的亮度和分离的明星将合理的一颗行星,那他们也做的随访观察与地面望远镜。

以一颗系外行星的形象,并不是一件容易的任务。可数十亿次行星的恒星比暗运行轨道附近,通常位于分离小于1/2000th角大小的恒星满月从他们。这个行星的数据是在大约10万倍-比星当昏暗的近红外波段。

“即使使用最望远镜,最好的解决,光从明亮的恒星泄漏出来,在该地区的暗行星位于,使他们无法看到。这是必要的,减了恒星发出的光明亮耀眼的阳光中看到微弱的形象,也就是说,行星上点可以藏在下面,“说雷Doyon蒙特利尔大学的。

多么光明的稳定性是分散在照相机,叫做-点扩散函数,关键是用“哈勃”图像恢复的行星。该工艺以影像作品的不同的恒星和结合创造一个点的一颗星,相似的研究行星。这需要相当稳定的明星,因为图像点是在不同的日子。大气条件将会从日常的望远镜,而不是一个太空望远镜,享受前所未有的图像稳定在不断参拜的目标。
