Query: Single Transit Candidates from K2: Detection and Period Estimation   Photometric surveys such as Kepler have the precision to identify exoplanet
and eclipsing binary candidates from only a single transit. K2, with its 75d
campaign duration, is ideally suited to detect significant numbers of
single-eclipsing objects. Here we develop a Bayesian transit-fitting tool
("Namaste: An Mcmc Analysis of Single Transit Exoplanets") to extract orbital
information from single transit events. We achieve favourable results testing
this technique on known Kepler planets, and apply the technique to 7 candidates
identified from a targeted search of K2 campaigns 1, 2 and 3. We find
EPIC203311200 to host an excellent exoplanet candidate with a period, assuming
zero eccentricity, of $540 ^{+410}_{-230}$ days and a radius of $0.51 \pm 0.05
R_{Jup}$. We also find six further transit candidates for which more follow-up
is required to determine a planetary origin. Such a technique could be used in
the future with TESS, PLATO and ground-based photometric surveys such as NGTS,
potentially allowing the detection of planets in reach of confirmation by Gaia.
