A Fourth Planet in the Kepler-51 System Revealed by Transit Timing Variations
The Astronomical JournalKepler-51 is a ≲1 Gyr old Sun-like star hosting three transiting planets with radii ≈6–9 R _⊕ and orbital periods ≈45–130 days. Transit timing variations (TTVs) measured with past Kepler and Hubble Space Telescope (HST) observations have been ...Kento Masuda, Jessica E. Libby-Roberts, John H. Livingston, Kevin B.

IV. Long-term Doppler Spectroscopy for 11 Stars Thought to Host Cool Giant Exoplanets
The Astrophysical Journal Supplement SeriesDiscovering and characterizing exoplanets at the outer edge of the transit method’s sensitivity has proven challenging owing to geometric biases and the practical difficulties associated with acquiring long observational baselines.Paul A.

The Astronomical JournalAn intriguing pattern among exoplanets is the lack of detected planets between approximately 1.5 R _⊕ and 2.0 R _⊕ . One proposed explanation for this “radius gap” is the photoevaporation of planetary atmospheres, a theory that can be tested by studying ...Aaron Householder, Lauren M. Weiss, James E.
