Query: Kepler-1708 b-i is likely undetectable with HST   The exomoon candidate Kepler-1708 b-i was recently reported using two
transits of Kepler data. Supported by a 1% false-positive probability, the
candidate is promising but requires follow-up observations to confirm/reject
its validity. In this short paper, we calculate the detectability of the
exomoon candidate's transit in the next window (March 2023) using the WFC3
instrument aboard the Hubble Space Telescope (HST). Using realistic noise
estimates, accounting for the visit-long trends, and propagating the model
posteriors derived using the Kepler data, we perform 50 injection-recovery
trials with Bayesian model selection. Defining a detection criterion that the
moon transit must be detected to a Bayes factor exceeding 10 using HST alone,
only 18 of the injections were recovered, yielding a true-positive probability
(TPP) of $(36\pm7)$%. Despite HST's superior aperture to Kepler, both
instrumental systematics and the compactness of the candidate exomoon's orbit
typically obfuscate a strong detection. Although the noise properties of the
James Webb Space Telescope (JWST) have not yet been characterized in flight, we
estimate the signal would be easily recovered using NIRSpec operating in its
Bright Object Time Series mode.
