An Estimate of the Yield of Single-Transit Planetary Events from the Transiting Exoplanet Survey Satellite

Understand

We present a semi-analytic estimate of the expected yield of single-transit planets from the Transiting Exoplanet Survey Satellite (TESS).

• We use the TESS Candidate Target List 6 (CTL-6) as an input catalog of over 4 million sources.
• We predict that from the 200,000 stars selected to be observed with the high-cadence postage stamps with the highest CTL-6 priority, there will be 241 single-transit events caused by planets detectable at a signal-to-noise ratio of SNR$\ge7.3$.
• We find a lower limit of an additional 977 events caused by single-transit planets in the full frame images (FFI); this is a lower limit because the CTL-6 is incomplete below a TESS magnitude of $T>12$.
