Multi-GPU maximum entropy image synthesis for radio astronomy
M. Cárcamo, P. Román, S. Casassus +2
The maximum entropy method (MEM) is a well known deconvolution technique in radio-interferometry. This method solves a non-linear optimization problem with an entropy regularizatio…
A compact concentration of large grains in the HD142527 protoplanetary dust trap
Simon Casassus, Chris Wright, Sebastian Marino +11
A pathway to the formation of planetesimals, and eventually giant planets, may occur in concentrations of dust grains trapped in pressure maxima. Dramatic crescent-shaped dust conc…
Accretion kinematics through the warped transition disk in HD142527 from resolved CO(6-5) observations
Simon Casassus, Sebastian Marino, Sebastian Perez +10
The finding of residual gas in the large central cavity of the HD142527 disk motivates questions on the origin of its non-Keplerian kinematics, and possible connections with planet…
Planet formation signposts: observability of circumplanetary disks via gas kinematics
Sebastian Perez, Alex Dunhill, Simon Casassus +5
The identification of on-going planet formation requires the finest angular resolutions and deepest sensitivities in observations inspired by state-of-the-art numerical simulations…
Compact dust concentration in the MWC 758 protoplanetary disk
S. Marino, S. Casassus, S. Perez +5
The formation of planetesimals requires that primordial dust grains grow from micron- to km-sized bodies. Dust traps caused by gas pressure maxima have been proposed as regions whe…
CO gas inside the protoplanetary disk cavity in HD 142527: disk structure from ALMA
Sebastian Perez, S. Casassus, F. Ménard +6
Inner cavities and annular gaps in circumstellar disks are possible signposts of giant planet formation. The young star HD 142527 hosts a massive protoplanetary disk with a large c…
Observations of gas flows inside a protoplanetary gap
Simon Casassus, Gerrit van der Plas, Sebastian Perez M. +16
Gaseous giant planet formation is thought to occur in the first few million years following stellar birth. Models predict that giant planet formation carves a deep gap in the dust…
