The true masses of radial-velocity exoplanets constrained by stability
Xander Byrne, Amy Bonsor
Exoplanets discovered with the radial velocity method suffer from a mass-inclination degeneracy: only the minimum mass is measured. An exoplanet with an Ea…

To be lensed or not to be lensed: on the nature of the alleged high-z lensed quasars J0109-5424 and P170+20
Aurora Mata-Sanchez, Emanuele P. Farina, Anniek J. Gloudemans +17
We present a detailed multi-wavelength analysis of two gravitationally lensed z>6 quasar candidates: J0109-5424 and P170+20. Using JWST/NIRSpec near-infrared data from the Aether s…

The Barnard's Star Planetary System: Stability, Composition, and Evolution of Four Sub-Earth Exoplanets
Xander Byrne, Claire Marie Guimond, Amy Bonsor +3
Barnard's Star is the nearest single star to the Sun (1.8 pc), and hosts four recently-discovered planets. The star also has well-characterized stellar abundances of important rock…
