在 GJ 436b 附近嗎??



難到還有個 UCF-1.02 ?

In addition to UCF-1.01, Stevenson and his colleagues noticed hints of a third planet, dubbed UCF-1.02, orbiting GJ 436. Spitzer has observed evidence of the two new planets several times each. However, even the most sensitive instruments are unable to measure exoplanet masses as small as UCF-1.01 and UCF-1.02, which are perhaps only one-third the mass of Earth. Knowing the mass is required for confirming a discovery, so the paper authors are cautiously calling both bodies exoplanet candidates for now.

不過先前 KOI961 不是有發現

UCF-1.01和 UCF-1.02 都是在GJ 436旁的兩個可能的行星候選者 (就是還沒完全被確認)

Of the approximately 1,800 stars identified by NASA’ Kepler space telescope as candidates for having planetary systems, just three are verified to contain sub-Earth-sized exoplanets. Of these, only one exoplanet is thought to be smaller than the Spitzer candidates, with a radius similar to Mars, or 57 percent that of Earth.

之前Kepler發現的行星候選者裡面只有KOI961 比UCF-1.01小

KOI961直徑約地球的57%
UCF-1.01直徑約地球的67%

[peter]

KOI961直徑約地球的57% => koi 是 kelper 計劃 

UCF-1.01  => 那 ucf ??該不會是 uncertify

到底有多少找exoplanet 計畫 ?
