    • A gap in the planetesimal disc around HD 107146 and asymmetric warm dust emission revealed by ALMA 

      Marino, S.; Carpenter, J.; Wyatt, M.; Booth, M.; Casassus Montero, Simón; Faramaz, V.; Guzman, V.; Hughes, A.; Isella, A.; Kennedy, G.; Matra, L.; Ricci, L.; Corder, S. (Oxford University Press, 2018)
      While detecting low mass exoplanets at tens of au is beyond current instrumentation, debris discs provide a unique opportunity to study the outer regions of planetary systems. Here we report new ALMA observations of the ...
    • Exocometary gas in the HD 181327 debris ring 

      Marino, S.; Matra, L.; Stark, C.; Wyatt, M. C.; Casassus Montero, Simón; Kennedy, G.; Rodríguez, D.; Zuckerman, B.; Pérez, S.; Dent, William R. F.; Kuchner, M.; Hughes, A.M.; Schneider, G.; Steele, A.; Roberge, A.; Donaldson, J.; Nesvold, E. (2016)
      An increasing number of observations have shown that gaseous debris discs are not an exception. However, until now, we only knew of cases around A stars. Here we present the first detection of (CO)-C-12 (2-1) disc emission ...
    • Spiral arms in the protoplanetary disc HD100453 detected with ALMA: evidence for binary-disc interaction and a vertical temperature gradient 

      Rosotti, G. P.; Benisty, M.; Juhasz, A.; Teague, R.; Clarke, C.; Dominik, C.; Dullemond, C. P.; Klaassen, P. D.; Matra, L.; Stolker, T. (Oxford Univ Press, 2019)
      Scattered light high-resolution imaging of the protoplanetary disc orbiting HD100453 shows two symmetric spiral arms, possibly launched by an external stellar companion. In this paper, we present new, sensitive high-resolution ...
