TL;DR: In this article, the mass and density of a K-dwarf Wolf 503 (HIP 67285) was determined using radial velocity measurements from four instruments, and a joint radial velocity-transit fit was conducted to constrain the eccentricity at $0.41 ± 0.05.

TL;DR: The Kepler giant planet survey (KGPS) as mentioned in this paper has been used to study the relationship between small and giant exoplanets and their associated properties, including their relationship with the architectural properties of close-in, sub-Neptune sized ex-planets.
Erratum: “Giant Outer Transiting Exoplanet Mass (GOT ‘EM) Survey. II. Discovery of a Failed Hot Jupiter on a 2.7 yr, Highly Eccentric Orbit” (2021, AJ, 162, 154)

TL;DR: In this article, the discovery of Kepler-129 d was presented based on six years of radial velocity (RV) observations from Keck/HIRES, which is an hierarchical system consisting of two tightly-packed inner planets and an external companion whose mass is close to the deuterium burning limit.

TL;DR: A 9-year transit-timing campaign reveals four large planets orbiting young star V1298 Tau have low masses, nearly circular orbits, and will contract to form a typical compact super-Earth and sub-Neptune system, similar to the Galaxy's most common planetary systems.
