Kepler-39b - Wikipedia
Kepler-39b (formerly known as KOI-423b), is a confirmed extrasolar object (either a Jovian planet or brown dwarf because of its mass) discovered orbiting the F-type star Kepler-39. It is eighteen times more massive than Jupiter, and is about five fourths its size.

Determining Exoplanetary Oblateness Using Transit Depth …
2017年8月29日 · Using Kepler photometry, we examined the brown dwarf Kepler-39b and the warm Saturn Kepler-427b. We could not reliably constrain the oblateness of Kepler-39b. We find transit depth variations for Kepler-427b at 90.1% significance ( 1.65σ) consistent with a precession period of Pprec = 5.45+0.46−0.37 years and an oblateness, f = 0.19+0.32−0.16.
