TESS Planets In Known Radial Velocity Cold Jupiter Systems: Hot Super Earth Occurrence Is Enhanced By Cold Jupiters

by Keith CowingFebruary 14, 2026February 14, 2026

The correlation between inner super-Earths (SEs) and outer cold Jupiters (CJs) provides an important constraint on the formation and dynamical evolution of planetary systems. Previous studies have suggested a positive […]

Planetary distances (circular approximation) from the HZs in relation to the planetary eccentricities. The eccentricity is either the assumed value, an upper limit, or the actual eccentricity. The left panel conveys the full data set, whereas the right panel conveys a zoomed-in portion. Error bars for the non-zero eccentricities are given as well. HD 26161 is not included due to its outlying distance of 17.82 au. -- astro-ph.EP

Statistics And Habitability of F-type Star–Planet Systems

by Keith CowingJuly 24, 2024July 24, 2024

F-type star–planet systems represent an intriguing case for habitability studies. Although F-type stars spend considerably less time on the main-sequence than G, K, and M-type stars, they still offer a […]
