The Effect of Binarity on Circumstellar Disk Evolution
Scott A. Barenfeld, John M. Carpenter, Anneila I. Sargent +6
We present new results on how the presence of stellar companions affects disk evolution based on a study of the 5-11 Myr old Upper Scorpius OB Association. Of the 50 G0-M3 Upper Sc…
Measurement of Circumstellar Disk Sizes in the Upper Scorpius OB Association with ALMA
Scott A. Barenfeld, John M. Carpenter, Anneila I. Sargent +2
We present detailed modeling of the spatial distributions of gas and dust in 57 circumstellar disks in the Upper Scorpius OB Association observed with ALMA at sub-millimeter wavele…
The Closest Known Flyby of a Star to the Solar System
Eric E. Mamajek, Scott A. Barenfeld, Valentin D. Ivanov +4
Passing stars can perturb the Oort Cloud, triggering comet showers and potentially extinction events on Earth. We combine velocity measurements for the recently discovered, nearby,…
Empirical Limits on Radial Velocity Planet Detection for Young Stars
Lynne Hillenbrand, Howard Isaacson, Geoffrey Marcy +3
We report initial results from our long term search using precision radial velocities for planetary-mass companions located within a few AU of stars younger than the Sun. Based on…
A Kine-Chemical Investigation of the AB Dor Moving Group "Stream"
Scott A. Barenfeld, Eric J. Bubar, Eric E. Mamajek +1
The AB Dor Moving Group consists of a "nucleus" of ~10 stars at d ~ 20 pc, along with dozens of purported "stream" members distributed across the sky. We perform a chemical and kin…
