Abstract:
We recently used near-infrared spectroscopy to improve the
characterization of 76 low-mass stars around which K2 had detected 79
candidate transiting planets. 29 of these worlds were new discoveries
that had not previously been published. We calculate the false positive
probabilities that the transit-like signals are actually caused by
non-planetary astrophysical phenomena and reject five new transit-like
events and three previously reported events as false positives. We
also statistically validate 17 planets (7 of which were previously
unpublished), confirm the earlier validation of 22 planets, and
announce 17 newly discovered planet candidates. Revising the
properties of the associated planet candidates based on the updated
host star characteristics and refitting the transit photometry, we
find that our sample contains 21 planets or planet candidates with
radii smaller than 1.25 R⊕, 18 super-Earths (1.25-2 R⊕),
21 small Neptunes (2-4 R⊕), three large Neptunes (4-6 R⊕),
and eight giant planets (>6 R⊕). Most of these planets are highly
irradiated, but EPIC 206209135.04 (K2-72e, 1.29-0.13+0.14 R⊕),
EPIC 211988320.01 (Rp=2.86-0.15+0.16 R⊕), and
EPIC 212690867.01 (2.20-0.18+0.19 R⊕) orbit within optimistic
habitable zone boundaries set by the "recent Venus" inner limit and
the "early Mars" outer limit. In total, our planet sample includes
eight moderately irradiated 1.5-3 R⊕ planet candidates
(Fp~<20 F⊕) orbiting brighter stars (Ks<11) that are well-suited
for atmospheric investigations with the Hubble, Spitzer, and/or James Webb
Space Telescopes. Five validated planets orbit relatively bright stars
(Kp<12.5) and are expected to yield radial velocity semi-amplitudes of
at least 2 m/s. Accordingly, they are possible targets for radial velocity
mass measurement with current facilities or the upcoming generation of
red optical and near-infrared high-precision RV spectrographs.
Description:
In the first paper in this series (Dressing et al. 2017ApJ...836..167D 2017ApJ...836..167D),
we presented near-infrared (NIR) spectra and determined stellar parameters
for 144 potentially low-mass stars observed by K2 during Campaigns 0-7
(2014 May 30-2015 December 26). In this paper, we use our previously
determined stellar parameters combined with planet candidate lists to
generate a catalog of K2 planetary systems orbiting low-mass stars.
The majority of the 74 systems in the cool dwarf sample were selected
from unpublished candidate lists provided by A. Vanderburg (53 stars
hosting 59 candidates) or the K2 California Consortium (K2C2; 43 stars
hosting 54 candidates); several stars appear on both lists and many of
the K2C2 targets were later published in Crossfield et al. (2016,
J/ApJS/226/7).

Note (1): Note as follows:
c = The Gemini/DSSI speckle images of EPIC 201637175 did not reveal any
companions, but Subaru/HSC imaging displayed a second star roughly 12% as
bright as EPIC 201637175. The separation of the two stars is approximately
2" (Sanchis-Ojeda et al. 2015ApJ...812..112S 2015ApJ...812..112S);
d = The follow-up images of EPIC 210558622 did not reveal any companions, but
a second set of spectral lines was detected in the Keck/HIRES
reconnaissance spectrum (Crossfield et al. 2016, J/ApJS/226/7).
Note (2): These point sensitivity estimates provide a rough view of whether the
image provides deep or shallow limits on the presence of nearby companions.
As shown in Figure 1, the contrast achieved improves with increasing
separation from the target star. We use the full separation-dependent contrast
curves for our false positive probability estimates.

Note (1): EPIC 211924657 displays transit timing variations, but our fits
assumed a linear ephemeris.

Global notes:
Note (G1): Candidate dispositions are defined as follows:
CP = Confirmed Planet;
PC = Planet Candidate;
FP = False Positive;
UK = Unknown.
Note (G2): Note that VESPA operates in a statistical fashion and that the
reported FPP may occasionally be higher for the FFP-low case than for the
FFP-high case due to changes in the simulated population of stars.
Note (G3): Rows without definitive answers mark stars without follow-up images
posted to the ExoFOP-K2 website. Note that planet radius estimates are not
corrected for flux dilution due to the presence of nearby stars.
