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…
Homogeneous Analysis of the Dust Morphology of Transition Disks Observed with ALMA: Investigating dust trapping and the origin of the cavities
P. Pinilla, M. Tazzari, I. Pascucci +11
We analyze the dust morphology of 29 transition disks (TDs) observed with ALMA at (sub-) millimeter-emission. We perform the analysis in the visibility plane to characterize the to…
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…
A Neptune-sized transiting planet closely orbiting a 5-10-million-year-old star
Trevor J. David, Lynne A. Hillenbrand, Erik A. Petigura +10
Theories of the formation and early evolution of planetary systems postulate that planets are born in circumstellar disks, and undergo radial migration during and after dissipation…
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,…
