Exoplanet Discoveries and Updates

In a paper published in 2019 in Astronomy & Astrophysiscs, scientists analyzing radial velocity data found a regular, long-period spike. Said spike could be explained by a Jupiter-analog planet orbiting at around 5 AU. However, the planet could be as heavy as 5 Jupiter masses and orbit anywhere between 3 and 20 AU from its parent star.[68]

A mesojovian may exist at inner edge of debris disk at ~ 5AU. Will Zeus return?

Interestingly enough, an earlier paper rules out any planet more massive than Neptune orbiting at 5 AU.
