Query: Precovery of TESS Single Transits with KELT   During the TESS prime mission, 74% of the sky area will only have an
observational baseline of 27 days. For planets with orbital periods longer than
13.5 days, TESS can only capture one or two transits, and the planet
ephemerides will be difficult to determine from TESS data alone. Follow-up
observations of transits of these candidates will require precise ephemerides.
We explore the use of existing ground-based wide-field photometric surveys to
constrain the ephemerides of the TESS single-transit candidates, with a focus
on the Kilodegree Extremely Little Telescope (KELT) survey. We insert simulated
TESS-detected single transits into KELT light curves, and evaluate how well
their orbital periods can be recovered. We find that KELT photometry can be
used to confirm ephemerides with high accuracy for planets of Saturn size or
larger with orbital periods as long as a year, and therefore span a wide range
of planet equilibrium temperatures. In a large fraction of the sky we recover
30% to 50% of warm Jupiter systems (planet radius of 0.9 to 1.1 R_J and 13.5 <
P < 50 days), 5% to 20% of temperate Jupiters (50 < P < 300 days), and 10% to
30% of warm Saturns (planet radius of 0.5 to 0.9 R_J and 13.5 < P < 50 days).
The resulting ephemerides can be used for follow-up observations to confirm
candidates as planets, eclipsing binaries, or other false positives, as well as
to conduct detailed transit observations with facilities like JWST or HST.
