Abstract:
We provide updates to the Kepler planet candidate sample based upon
nearly two years of high-precision photometry (i.e., Q1-Q8). From an
initial list of nearly 13400 threshold crossing events, 480 new host
stars are identified from their flux time series as consistent with
hosting transiting planets. Potential transit signals are subjected to
further analysis using the pixel-level data, which allows background
eclipsing binaries to be identified through small image position
shifts during transit. We also re-evaluate Kepler Objects of Interest
(KOIs) 1-1609, which were identified early in the mission, using
substantially more data to test for background false positives and to
find additional multiple systems. Combining the new and previous KOI
samples, we provide updated parameters for 2738 Kepler planet
candidates distributed across 2017 host stars. From the combined
Kepler planet candidates, 472 are new from the Q1-Q8 data examined in
this study. The new Kepler planet candidates represent ∼40% of the
sample with RP∼1R⊕ and represent ∼40% of the low equilibrium
temperature (Teq<30 K) sample. We review the known biases in the
current sample of Kepler planet candidates relevant to evaluating
planet population statistics with the current Kepler planet candidate
sample.
Description:
In 2011 November, the Q1-Q8 (22 months of data) Kepler pipeline run
generated one or more TCEs (threshold crossing events) for ∼13400
Kepler targets out of ∼191000 targets searched.
