    The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): III. The vertical structure of debris disks
    Context. Debris disks ─ collisionally sustained belts of dust and sometimes gas around main sequence stars ─ are remnants of planet formation processes and are...
  • Publication
    The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): IV. CO gas imaging and overview
    Context. CO gas is detected in a significant number (~20) of debris discs (exoKuiper belts), but understanding its origin and evolution remains elusive. Crucial...
  • Publication
    The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): IX. Gas-driven origin for the continuum arc in the debris disc of HD121617
    Context. Debris discs were long considered to be largely gas-free environments, where dynamical evolution is governed primarily by collisional fragmentation...
  • Publication
    The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): V. Comparison between scattered light and thermal emission
    Context. 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...
  • Publication
    The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): VI. Asymmetries and offsets
    Context. Asymmetries in debris discs provide unique clues to understand the evolution and architecture of planetary systems. Previous studies of debris discs 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
    Context. CO gas has been detected in ~20 debris discs, typically classified as CO-poor or CO-rich. We present observations of the CO-rich HD 121617 debris disc...

    The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): VIII. A dust arc and non-Keplerian gas kinematics in HD 121617
    Context. ExoKuiper belts around young A-type stars often host CO gas, whose origin is still unclear. The ALMA survey to Resolve exoKuiper belt Substructures...
  • Publication
    The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): X. Interpreting the peculiar dust rings around HD 131835
    Context. Dusty discs detected around main-sequence stars are thought to be signs of planetesimal belts in which the dust distribution is shaped by collisional...
  • Publication
    The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): XI. Gas-dust interactions and radial offsets between micron and millimetre-sized grains
    Context. The dust observed in debris disks is the result of a collisional cascade initiated from approximately kilometer-sized parent bodies. Using near...
