The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) XI: Gas-dust interactions and radial offsets between micron and millimetre-sized grains

J. Olofsson, M. R. Jankovic, S. Marino +22

The dust observed in debris disks is the result of a collisional cascade initiated from km-sized parent bodies. Using near-infrared to sub-millimeter observations, we can pr…

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) V: Comparison between scattered light and thermal emission

J. Milli, J. Olofsson, M. Bonduelle +33

Debris discs are analogues to our own Kuiper belt around main-sequence stars and are therefore referred to as exoKuiper belts. They have been resolved at high angular resolution at…

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) VII: Optically thick gas with broad CO gaussian local line profiles in the HD 121617 disc

A. Brennan, L. Matrà, S. Mac Manamon +24

CO gas has been detected in 20 debris discs. We present ALMA observations of the CO-rich HD 121617 debris disc from the ARKS survey. Using high-resolution Band 7 observations…

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): VI. Asymmetries and offsets

J. B. Lovell, A. S. Hales, G. M. Kennedy +33

Asymmetries in debris discs provide unique clues to understand the evolution and architecture of planetary systems.** The aim of the ALMA survey to Resolve exoKuiper belt Substruct…

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS). X. Interpreting the peculiar dust rings around HD 131835

M. R. Jankovic, N. Pawellek, J. Zander +27

Dusty discs detected around main-sequence stars are thought to be signs of planetesimal belts in which the dust distribution is shaped by collisional and dynamical processes, inclu…

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) IV: CO gas imaging and overview

S. Mac Manamon, L. Matrà, S. Marino +29

CO gas is detected in a significant number of debris discs, but its origin and evolution remains unclear. Key constraints are its mass and spectro-spatial distribution, which are c…

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) VIII: A dust arc and non-Keplerian gas kinematics in HD 121617

S. Marino, V. Gupta, P. Weber +25

ExoKuiper belts around young A-type stars often host CO gas, whose origin is still unclear. The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) includes 6 of these gas-b…

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) I: Motivation, sample, data reduction, and results overview

S. Marino, L. Matrà, A. M. Hughes +39

The outer regions of planetary systems host dusty debris discs analogous to the Kuiper belt (exoKuiper belts), which provide crucial constraints on planet formation and evolution p…

Rave: A non-parametric method for recovering the surface brightness and height profiles of edge-on debris disks

Yinuo Han, Mark C. Wyatt, Luca Matra

Extrasolar analogues of the Solar System's Kuiper belt offer unique constraints on outer planetary system architecture. Radial features such as the sharpness of disk edges and subs…

AU-scale radio imaging of the wind collision region in the brightest and most luminous non-thermal colliding wind binary Apep

B. Marcote, J. R. Callingham, M. De Becker +5

The recently discovered colliding-wind binary (CWB) Apep has been shown to emit luminously from radio to X-rays, with the emission driven by a binary composed of two Wolf-Rayet (WR…

The extreme colliding-wind system Apep: resolved imagery of the central binary and dust plume in the infrared

Y. Han, P. G. Tuthill, R. M. Lau +6

The recent discovery of a spectacular dust plume in the system 2XMM J160050.7-514245 (referred to as "Apep") suggested a physical origin in a colliding-wind binary by way of the "P…

Two Wolf-Rayet stars at the heart of colliding-wind binary Apep

J. R. Callingham, P. A. Crowther, P. M. Williams +4

Infrared imaging of the colliding-wind binary Apep has revealed a spectacular dust plume with complicated internal dynamics that challenges standard colliding-wind binary physics.…
