Mass-radius diagram for WASP-132c. The lines show the massradius relation for a pure water model (blue), an Earth-like model (green), and a pure-iron model (gray). The other exoplanets are taken from the PlanetS catalouge (Otegi et al. 2020). -- astro-ph.EP

Refining the WASP-132 Multi-planetary System: Discovery of a Cold Giant Planet and Mass Measurement of a hot Super-Earth

by Keith CowingJune 27, 2024June 27, 2024

Hot Jupiters generally do not have nearby planet companions, as they may have cleared out other planets during their inward migration from more distant orbits.

Mass-Radius Diagram comparing the data from the PlanetS catalog and the data from NASA Exoplanet Archive to highlight the effects of our selection criteria and our detailed study of references. The grey dots represented the default parameters from NASA, the light blue triangles the same but filtered with our criteria on uncertainties and the blue dots correspond to the PlanetS catalog. The resulting M-R relationships from Sect.2.2 are in solid red lines with the confidence intervals represented by the shaded red areas. The transitions between the three populations are represented by the composition line of 20% water at 650 K from Luo et al. (2024) in dashed orange and the dotted black line at 138 M⊕. -- astro-ph.EP

From Super-Earths to Sub-Neptunes: Observational Constraints and Connections to Theoretical Models

by Keith CowingJune 7, 2024June 7, 2024

We update the PlanetS catalog of transiting planets with precise and robust mass and radius measurements and use this comprehensive catalog to explore Mass-Radius (M-R) diagrams.
