Do White Dwarfs Sample Water-Rich Planetary Material?
Isabella L. Trierweiler, Carl Melis, Érika Le Bourdais +9
Polluted white dwarfs offer a unique way to directly probe the compositions of exoplanetary bodies. We examine the water content of accreted material using the oxygen abundances of…
Characterizing the Chemistry of Planetary Materials Around White Dwarf Stars
B. Zuckerman, E. D. Young
Planetary systems that orbit white dwarf stars can be studied via spectroscopic observations of the stars themselves. Numerous white dwarfs are seen to have accreted mostly rocky m…
The Chemical Composition of an Extrasolar Kuiper-Belt-Object
S. Xu, B. Zuckerman, P. Dufour +3
The Kuiper Belt of our solar system is a source of short-period comets that may have delivered water and other volatiles to Earth and the other terrestrial planets. However, the di…
A Pilot Search for Evidence of Extrasolar Earth-analog Plate Tectonics
M. Jura, B. Klein, S. Xu +1
Relative to calcium, both strontium and barium are markedly enriched in Earth's continental crust compared to the basaltic crusts of other differentiated rocky bodies within the so…
26Al in the Early Solar System: Not so Unusual After All
M. Jura, S. Xu, E. D. Young
Recently acquired evidence shows that extrasolar asteroids exhibit over a factor of 100 variation in the iron to aluminum abundance ratio. This large range likely is a consequence…
