Direct imaging and astrometric detection of a gas giant planet orbiting an accelerating star
Burrows, Adam; Currie, Thayne; Kwon, Jungmi +31 more
Direct imaging of gas giant exoplanets provides information on their atmospheres and the architectures of planetary systems. However, few planets have been detected in blind surveys with direct imaging. Using astrometry from the Gaia and Hipparcos spacecraft, we identified dynamical evidence for a gas giant planet around the nearby star HIP 99770.…
A VLBI resolution of the Pleiades distance controversy
Stauffer, John R.; Bower, Geoffrey C.; Melis, Carl +2 more
Because of its proximity and its youth, the Pleiades open cluster of stars has been extensively studied and serves as a cornerstone for our understanding of the physical properties of young stars. This role is called into question by the “Pleiades distance controversy,” wherein the cluster distance of 120.2 ± 1.5 parsecs (pc) as measured by the op…
