Modeling the Impact of Moderate External UV Irradiation on Disk Chemistry

The Astrophysical Journal
The chemistry within a protoplanetary disk is greatly affected by external radiation from the local stellar environment. Previous work has focused on extreme radiation fields, representative of the center of something like the Orion Nebula Cluster ...

Hidden Binaries in Star-forming Regions

The Astrophysical Journal
A significant fraction of, and possibly all, stars form in binary or multiple systems. For solar-mass stars in the Galactic field, the distribution of orbital separations is log-normal over 7 orders of magnitude, from 10 ^−2  to 10 ^5 au.
