太阳系外行星的直接成像:探测到的行星和候选行星的均匀比较

Direct Imaging of Extra-solar Planets - Homogeneous Comparison of Detected Planets and Candidates

R. Neuhäuser, T. O. B. Schmidt

摘要:

通过搜索文献,我们发现了25颗有直接成像的行星和候选者的恒星。我们收集了所有这些物体的光度和光谱信息,以均匀的方式导出它们的光度,同时考虑到热辐射校正。使用理论演化模型,我们可以从光度、温度和年龄来估计质量。根据我们的质量估计,它们的质量都可以低于25 Jup质量,因此它们被认为是行星。

英文摘要:

Searching the literature, we found 25 stars with directly imaged planets and candidates. We gathered photometric and spectral information for all these objects to derive their luminosities in a homogeneous way, taking a bolometric correction into account. Using theoretical evolutionary models, one can then estimate the mass from luminosity, temperature, and age. According to our mass estimates, all of them can have a mass below 25 Jup masses, so that they are considered as planets.
