摘要

我用分析软件AstroImageJ对一颗恒星GSC 3281-0800进行了光度测定,这颗恒星已知是系外行星HAT-P-32b的宿主。我根据凌日期间拍摄的一系列图像绘制了测量图,通过地面上的数字CCD相机提供的ADU计数。我能够建立一个明确的光曲线,并了解更多关于这颗系外行星的特性。

Detection of Exoplanets Using the Transit Method
I conducted differential photometry on a star GSC 3281-0800, a known host to exoplanet HAT-P-32b, using analysis software AstroImageJ. I plotted the measurements from a series of images taken during the transit, via ADU count given from an earth-based digital CCD camera. I was able to establish a definite light curve and learn more about the properties of this exoplanet.
