ALMA Measurements of Circumstellar Material in the GQ Lup System
Meredith A. MacGregor, David J. Wilner, Ian Czekala +7
We present ALMA observations of the GQ Lup system, a young Sun-like star with a substellar mass companion in a wide-separation orbit. These observations of 870 m continuum and C…
ALMA Observations of the Debris Disk of Solar Analogue Tau Ceti
Meredith A. MacGregor, Samantha M. Lawler, David J. Wilner +4
We present 1.3 mm observations of the Sun-like star Ceti with the Atacama Large Millimeter/submillimeter Array (ALMA) that probe angular scales of '' (4 AU). This first…
Constraints on Planetesimal Collision Models in Debris Disks
Meredith A. MacGregor, David J. Wilner, Claire Chandler +6
Observations of debris disks offer a window into the physical and dynamical properties of planetesimals in extrasolar systems through the size distribution of dust grains. In parti…
