Abstract:
Radial velocity (RV) surveys have detected hundreds of exoplanets
through their gravitational interactions with their host stars. Some
will be transiting, but most lack sufficient follow-up observations to
confidently detect (or rule out) transits. We use published stellar,
orbital, and planetary parameters to estimate the transit
probabilities for nearly all exoplanets that have been discovered via
the RV method. From these probabilities, we predict that
25.5-0.7+0.7 of the known RV exoplanets should transit their host
stars. This prediction is more than double the amount of RV exoplanets
that are currently known to transit. The Transiting Exoplanet Survey
Satellite (TESS) presents a valuable opportunity to explore the
transiting nature of many of the known RV exoplanet systems. Based on
the anticipated pointing of TESS during its two-year primary mission,
we identify the known RV exoplanets that it will observe and predict
that 11.7-0.3+0.3 of them will have transits detected by TESS.
However, we only expect the discovery of transits for ∼3 of these
exoplanets to be novel (i.e., not previously known). We predict that
the TESS photometry will yield dispositive null results for the
transits of ∼125 RV exoplanets. This will represent a substantial
increase in the effort to refine ephemerides of known RV exoplanets.
We demonstrate that these results are robust to changes in the
ecliptic longitudes of future TESS observing sectors. Finally, we
consider how several potential TESS extended mission scenarios affect
the number of transiting RV exoplanets we expect TESS to observe.
Description:
We use published stellar, orbital, and planetary parameters to
estimate the transit probabilities for nearly all exoplanets that have
been discovered via the RV method.
