An SMA Molecular Inventory of the Edge-on Protoplanetary Disk Gomez's Hamburger
Erin M. Cusson, Lisa Wölfer, Richard Teague +10
Gomez's Hamburger (IRAS 18059-3211, GoHam) is a massive, edge-on protoplanetary disk that is potentially gravitationally unstable and hosts an overdensity that may be the site of a…
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) XI: Gas-dust interactions and radial offsets between micron and millimetre-sized grains

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) III: The vertical structure of debris disks
Brianna Zawadzki, Anna Fehr, A. Meredith Hughes +37
Debris disks -- collisionally sustained belts of dust and sometimes gas around main sequence stars -- are remnants of planet formation processes and are found in systems ${\gtrsim}…

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) 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) IX: Gas-driven origin for the continuum arc in the debris disc of HD 121617
Philipp Weber, Sebastián Pérez, Clément Baruteau +24
Debris discs were long considered to be largely gas-free environments governed by collisional fragmentation, gravitational stirring, and radiative forces. Recent CO detections show…
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…

Yinuo Han, Mark Wyatt, Kate Y. L. Su +13
The A1V star Oph, at a distance of 29.7 pc, is known from Spitzer imaging to host a debris disk with a large radial extent and from its spectral energy distribution to host inn…

Why dust pressure matters in debris discs
Elliot M. Lynch, Josh B. Lovell, Antranik A. Sefilian
There is a common assumption in the particulate disc community that the pressure in particulate discs is essentially zero and that the disc streamlines follow Keplerian orbits, in…
