Has the Kepler data been examined for light curves due to phase changes of non-transitting hot Jupiters and other?
Here's an example paper looking for phase curves of non-transiting planets in the Kepler data: Millholland &amp; Laughlin (2017) "Supervised Learning Detection of Sixty Non-transiting Hot Jupiter Candidates".

The candidates themselves can be found on this webpage.

Unfortunately I'm not aware of any RV followup on them to determine which of these candidates are actually planets.
