The typical technique for exoplanet detection using the transit method is to make up to several hundred observations of a target (or target pointing) each day for a number of days. This is necessary since exoplanet transits will often require only a few hours of elapsed time on a given day. The equivalent observations can be accumulated if less observations are collected over an extended period of time.
Using the Rubin/LSST configuration, we suggest that exoplanets could be detected in a small patch of the sky using this structure:
(1) Observations of the patch at least 10 times (20 times would be even better) over the course of each night
(2) The observations would be the standard 30 second snap
(3) The observations would be spaced at roughly equal intervals throughout the night This would require 30 minutes (15 minutes for the more aggressive 20 observations) between pointings. Making 10 observations that are consecutive (back-to-back) would not accomplish the requirement.
(4) The process would be repeated each day for the same patch until the mini-survey completes.
Is there a mini-survey (DDF or otherwise) already planned that would meet this objective?
If not, would it be possible to plan one using this rough outline?
