The ALMA survey to Resolve exoKuiper belt Substructures (ARKS)

S. Marino, V. Gupta, P. Weber, T. D. Pearce et autres

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 (ARKS) includes six of these gas-bearing belts, to characterise their dust and gas distributions and investigate the gas …

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS)

J. B. Lovell, A. S. Hales, G. M. Kennedy, S. Marino et autres

Context. Asymmetries in debris discs provide unique clues to understand the evolution and architecture of planetary systems. Previous studies of debris discs at (sub)millimetre wavelengths have suggested the presence of asymmetries in a wide variety of systems, yet the lack of sufficiently …

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS)

J. Milli, J. Olofsson, M. Bonduelle, R. Bendahan-West et autres

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 at high angular resolution at wavelengths spanning the optical/near-infrared to the submillimetre-millimetre regime. Short wavelengths can probe …

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS)

B. Zawadzki, A. Fehr, A. Meredith Hughes, E. Mansell et autres

Context. 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 ≳10 Myr old. Millimeter-wavelength observations are particularly important, as the grains probed by these …

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS)

S. Marino, L. Matrà, A. Meredith Hughes, J. Ehrhardt et autres

Context. 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 processes. ALMA dust observations have revealed a great diversity in terms of radii, widths, and …
