A Dust Trap in the Young Multiple System HD 34700
Peyton Benac, Luca Matra, David J. Wilner +6
Millimeter observations of disks around young stars reveal substructures indicative of gas pressure traps that may aid grain growth and planet formation. We present Submillimeter A…
The SHARDDS survey: first resolved image of the HD114082 debris disk in Lower Centaurus Crux with SPHERE
Zahed Wahhaj, Julien Milli, Grant Kennedy +17
We present the first resolved image of the debris disk around the 16+/-8 Myr old star, HD 114082. The observation was made in the H-band using the SPHERE instrument. The star is at…
Five steps in the evolution from protoplanetary to debris disk
Mark C. Wyatt, Olja Panic, Grant M. Kennedy +1
The protoplanetary disks of Herbig Ae stars eventually dissipate leaving a tenuous debris disk comprised of planetesimals and dust, as well as possibly gas and planets. This paper…
Science with an ngVLA: Debris disk structure and composition
Brenda Matthews, Jane Greaves, Grant Kennedy +3
Debris disks, comprised of planetsimal belts and the dust and gas produced by their mutual collisions, are the longest-lived phase of circumstellar disks. Typically much fainter in…
Near-infrared scattered light properties of the HR4796A dust ring: a measured scattering phase function from 13.6deg to 166.6deg
Julien Milli, Arthur Vigan, David. Mouillet +27
HR4796A is surrounded by a debris disc, observed in scattered light as an inclined ring. Past observations raised several questions. First, a strong brightness asymmetry detected i…
A Deep Search for Five Molecules in the 49 Ceti Debris Disk
Jessica Klusmeyer, A. Meredith Hughes, Luca Matra +9
Surprisingly strong CO emission has been observed from more than a dozen debris disks around nearby main-sequence stars. The origin of this CO is unclear, in particular whether it…
