    • Characterization of low-mass companion HD 142527 B 
      Christiaens, V.; Casassus Montero, Simón; Absil, O.; Kimeswenger, S.; Gómez González, Carlos; Girard, J.; Ramírez, R.; Wertz, O.; Zurlo, A.; Wahhaj, Z.; Flores, C.; Salinas, V.; Jordán, A.; Mawet, D. (EDP Sciences, 2018)
      Context. The circumstellar disk of the Herbig Fe star HD 142527 is host to several remarkable features including a warped inner disk, a 120 au-wide annular gap, a prominent dust trap and several spiral arms. A low-mass ...
    • Discovery of a point-like source and a third spiral arm in the transition disk around the Herbig Ae star MWC 758 
      Reggiani, M.; Christiaens, V.; Absil, O.; Barraza, M. (EDP Sciences, 2018)
      Context. Transition disks offer the extraordinary opportunity to look for newly born planets and to investigate the early stages of planet formation. Aims. In this context we observed the Herbig A5 star MWC 758 with ...
    • Nine Localized Deviations from Keplerian Rotation in the DSHARP Circumstellar Disks: Kinematic Evidence for ... 
      Pinte, C.; Price, D. J.; Ménard, F.; Duchene, G.; Christiaens, V.; Andrews, S. M.; Huang, J.; Hill, T.; van der Plas, G.; Pérez, L. M.; Isella, A.; Boehler, Y.; Dent, W. R. F.; Mentiplay, D.; Loomis, R. A. (IOP Publishing, 2020)
      We present evidence for localized deviations from Keplerian rotation, i.e., velocity "kinks," in 8 of the 18 circumstellar disks observed by the DSHARP program: DoAr 25, Elias 2-27, GW Lup, HD 143006, HD 163296, IM Lup, ...
    • Separating extended disc features from the protoplanet in PDS 70 using VLT/SINFONI 
      Christiaens, V.; Casassus Montero, Simón; Absil, O.; Cantalloube, F.; Gonzalez, C. Gomez; Girard, J.; Ramírez, R.; Pairet, B.; Salinas, V.; Price, D. J.; Pinte, C.; Quanz, S. P.; Jordán, A.; Mawet, D.; Wahhaj, Z. (Oxford University Press, 2019)
      Transition discs are prime targets to look for protoplanets and study planet.disc interactions. We present VLT/SINFONI observations of PDS 70, a transition disc with a recently claimed embedded protoplanet. We take advantage ...
    • The Carina high-contrast imaging project for massive stars (CHIPS): I. Methodology and proof of concept on ... 
      Rainot, A.; Reggiani, M.; Sana, H.; Bodensteiner, J.; Gómez González, C. A.; Absil, O.; Christiaens, V.; Delorme, P.; Almeida, L. A.; Caballero Nieves, S.; De Ridder, J.; Kratter, K.; Lacour, S.; Le Bouquin, J.-B.; Pueyo, L.; Zinnecker, H. (EDP Science, 2020)
      Context. Massive stars like company. However, low-mass companions have remained extremely di cult to detect at angular separations ( ) smaller than 1" (approx. 1000-3000 au considering typical distance to nearby massive ...
    • The widest Hα survey of accreting protoplanets around nearby transition disks 
      Zurlo, A.; Cugno, G.; Montesinos, M.; Peréz, S.; Cánovas, H.; Casassus Montero, Simón; Christiaens, V.; Cieza, L.; Huelamo, N. (EDP Sciences, 2020)
