(EDP Sciences, 2022)
      Context. Virtually all known exoplanets reside around stars with M < 2:3 M either due to the rapid evaporation of the protostellar disks or to selection effects impeding detections around more massive stellar hosts. Aims. ...

(EDP Sciences, 2018)
      Context. Young circumstellar disks are the birthplaces of planets. Their study is of prime interest to understand the physical and chemical conditions under which planet formation takes place. Only very few detections of ...

      Context. HD95086 is a young nearby Solar System analog hosting a giant exoplanet orbiting at 57 au from the star between an inner and outer debris belt. The existence of additional planets has been suggested as the mechanism ...
    • Optical Imaging Polarimetry of the LkCa 15 protoplanetary Disk with Sphere Zimpol 
      Thalmann, C.; Mulders, G. D.; Janson, M.; Olofsson, J.; Benisty, Myriam; Avenhaus, H.; Quanz, S. P.; Schmid, H. M.; Henning, Thomas; Buenzli, E.; Ménard, Francois; Carson, J. C.; Garufi, A.; Messina, S.; Dominik, C.; Leisenring, J.; Chauvin, G.; Meyer, M. R. (IOP Publishing, 2015)
      We present the first optical (590-890 nm) imaging polarimetry observations of the pre-transitional protoplanetary disk around the young solar analog LkCa 15, addressing a number of open questions raised by previous studies. ...
    • Perturbers: SPHERE detection limits to planetary-mass companions in protoplanetary disks
