      We present ALMA 1.3 mm continuum observations at 0."2 (25 au) resolution of Elias 2-24, one of the largest andbrightest protoplanetary disks in the Ophiuchus Molecular Cloud, and we report the presence of three partiallyresolved ...
    • Casassus Montero, Simón; Avenhaus, Henning; Pérez, Sebastián; Navarro, Víctor; Cárcamo, Miguel; Marino, Sebastián; Cieza, Luca; Quanz, Sascha P.; Alarcón, Felipe; Zurlo, Alice; Osses Alvarado, Axel; Rannou, Fernando R.; Román, Pablo E.; Barraza, Marcelo (Oxford University Press, 2018-07)
      Optical/IR images of transition discs (TDs) have revealed deep intensity decrements in the rings of HAeBes HD 142527 and HD 100453 that can be interpreted as shadowing from sharply tilted inner discs, such that the outer ...

(EDP Sciences, 2016)
      Context. Debris disks off er valuable insights into the latest stages of circumstellar disk evolution, and can possibly help us to trace the outcomes of planetary formation processes. In the age range 10 to 100 Myr, most ...
    • Lazzoni, C.; Desidera, S.; Marzari, F.; Avenhaus, Henning (EDP Sciences, 2018)
      Context. A large number of systems harboring a debris disk show evidence for a double belt architecture. One hypothesis for explaining the gap between the debris belts in these disks is the presence of one or more planets ...
    • Peréz Márquez, Sebastián; Casassus Montero, Simón; Hales, Antonio; Marino, Sebastián; Cheetham, Anthony; Zurlo, Alice; Cieza, Lucas; Dong, Ruobing; Alarcón, Felipe; Benítez Llambay, Pablo; Fomalont, Ed; Avenhaus, Henning (IOP, 2020)
      Using the Atacama Large Millimeter/submillimeter Array, we observed the young Herbig star HD 100546, host to a prominent disk with a deep, wide gap in the dust. The high-resolution 1.3 mm continuum observation reveals fine ...

(EDP Sciences, 2016)
      Context. The protoplanetary disk around the F-type star HD 135344B (SAO 206462) is in a transition stage and shows many intriguing structures both in scattered light and thermal (sub-) millimeter emission which are possibly ...
