Observational constraints on the likelihood of 26Al in planet-forming environmentsOPEN ACCESS
Megan Reiter accepted to A&A Letters PDF (OPEN ACCESS) “Recent work suggests that 26Al may determine the water budget in terrestrial exoplanets as its radioactive decay dehydrates planetesimals leading to rockier compositions. Here I consider…
