The Hunt for Exomoons with Kepler (HEK): II. Analysis of Seven Viable Satellite-Hosting Planet Candidates
The authors find no compelling exomoon evidence among seven selected Kepler candidates. Archival transit analysis and author-reported2012 stellar spectra support conditional mass limits; physical and predictive checks reject candidate fits. Noise, starspots and model assumptions limit inference. This provides research-method context, with no independent moon or UAP confirmation.

Not checked yet
- Seven candidates survive catalogue, multiplicity, model and noise filters from2321 KOIs,35 initially selected. Besides archival Kepler transits, page27 reports two KOI303 stellar spectra acquired August31,2012 at ApachePoint with ARCES. Individual operator/initiator and raw spectra are unavailable. These are host-star observations, with no new exomoon detection or unbiased population census.
- Better fits and formal significance do not suffice. KOI722’s7.5-sigma fit fails physical/zero-mass tests; other candidates fail physical, null-model or later-quarter predictive checks. Authors favor correlated noise or starspots. Mass, radius, orbit, density, detrending and prior assumptions constrain all limits; raw code/data replication is absent.
- Source95% mass-ratio quantiles are conditional:722<.016,365<.69,174<.86,1472<.037,1857<.028,303<.21,1876<.012. They do not universally exclude moons. Seven selected systems and four stronger limits are too few for meaningful population statistics; proposed larger surveys and acquisition/loss scenarios are not achieved findings.
- Retain conflicting literals: KOI365 prose−2.7±.2 versus Table8+3.40±.16; KOI1857 prose10.09±.16 versus Table17 10.06±.16; KOI303 not-close-binary wording versus later close-binary grouping. Figures3/5/6 visible panel counts disagree with captions. Stellar units, dense signs/subscripts and a chi-square referent remain unaudited; no silent correction or journal-original collation.
- Submission January9,2013 and revision/margin March6,2013 differ from draft header September28,2018 and PDF creationJune24,2021. DOI10.1088/0004-637X/770/2/101 is metadata. All supplied references/acknowledgments are reviewed;53 cited bodies, original deposit/journal bytes, model/posterior files and raw observations remain unreviewed in this lane. Earlier accepted family reading is preserved.
- Page33 attributes NASA Carl Sagan Fellowships to Kipping; partial NSF AST-1108686 and NASA NNX12AH91H support to Hartman/Bakos; NSF AST-1008890 to Nesvorný. Award dates, amounts, agreements and initiators are unknown. No separate Buchhave/Schmitt acknowledgement establishes their status.
