No statistically significant evidence for a correlation between stellar and planetary composition
Daisy A. Turner, Annelies Mortier, James G. Rogers +4
The chemical compositions of planets and their hosts stars are intrinsically linked, having formed from the same protostellar material. Characterising this relationship provides ke…
Testing the prevalence of hydrogen-silicate miscibility in young sub-Neptunes
James G. Rogers, Hilke E. Schlichting
Hydrogen-silicate miscibility can significantly alter the interior structure and thermal evolution of sub-Neptunes. We consider the interplay between this miscibility and stellar-d…
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…
Preparing for the Early eVolution Explorer: Detecting the Primordial, Transiting Exoplanet Population
George Zhou, James G. Rogers, Jennifer A. Burt +17
The close-in small planet population may be formed either with hydrogen/helium dominated envelopes or with water-rich interiors. Both scenarios reproduce the present day planet pop…
Using observations of escaping H/He to constrain the atmospheric composition of sub-Neptunes
James G. Rogers, James E. Owen, Ethan Schreyer +1
The internal composition of sub-Neptunes remains a prominent unresolved question in exoplanetary science. We present a technique to place constraints on envelope mean molecular wei…
