Icy Exomoons Evidenced by Spallogenic Nuclides in Polluted White Dwarfs
Alexandra E. Doyle, Steven J. Desch, Edward D. Young
We present evidence that excesses in Be in polluted white dwarfs (WDs) are the result of accretion of icy exomoons that formed in the radiation belts of giant exoplanets. Here we u…
A Giant Planet Candidate Transiting a White Dwarf
Andrew Vanderburg, Saul A. Rappaport, Siyi Xu +61
Astronomers have discovered thousands of planets outside the solar system, most of which orbit stars that will eventually evolve into red giants and then into white dwarfs. During…
Where are the Extrasolar Mercuries?
Alexandra E. Doyle, Beth Klein, Hilke E. Schlichting +1
We utilize observations of 16 white dwarf stars to calculate and analyze the oxidation states of the parent bodies accreting onto the stars. Oxygen fugacity, a measure of overall o…
Oxygen fugacities of extrasolar rocks: Evidence for an Earth-like geochemistry of exoplanets
Alexandra E. Doyle, Edward D. Young, Beth Klein +2
Oxygen fugacity is a measure of rock oxidation that influences planetary structure and evolution. Most rocky bodies in the Solar System formed at oxygen fugacities approximately fi…
