    • A Resolved and Asymmetric Ring of PAHs within the Young Circumstellar Disk of IRS 48 
      Schworer, Guillaume; Lacour, Sylvestre; Huélamo, Nuria; Pinte, Christophe; Chauvin, G.; du Foresto, Vincent Coudé; Ehrenreich, David; Girard, Julien; Tuthill, Peter (IOP Publishing, 2017)
      For one decade, the spectral type and age of the rho Oph object IRS-48 were subject to debate. and mystery. Modeling its disk with mid-infrared to millimeter observations led to various explanations to account for the ...
    • Discovery of concentric broken rings at sub-arcsec separations in the HD141569A gas-rich, debris disk with ... 
      Perrot, C.; Boccaletti, A.; Pantin, Enrique; Augereau, Jean-Charles; Lagrange, Anne Marie; Galicher, R.; Maire, Anne-Lise; Mazoyer, Mille; Rousset, G.; Gratton, R.; Bonnefoy, M.; Brandner, W.; Buenzli, E.; Langlois, M.; Lannier, J.; Mesa, D.; Peretti, S.; Salter, G.; Sissa, Elena; Chauvin, G.; Desidera, S.; Feldt, M.; Vigan, A.; Di Folco, E.; Dutrey, A.; Pericaud, J.; Baudoz, P.; Benisty, Myriam; De Boer, J.; Garufi, A.; Girard, Julien H.; Ménard, Francois; Olofsson, J.; Quanz, S. P.; Mouillet, David; Christiaens, Valentin; Casassus Montero, Simón; Beuzit, Jean-Luc; Blanchard, P.; Carle, M.; Fusco, T.; Giro, E.; Hubin, N.; Maurel, D.; Moeller-Nilsson, O.; Sevin, A.; Weber, L. (EDP Sciences, 2016)
      Context. Transition disks correspond to a short stage between the young protoplanetary phase and older debris phase. Along this evolutionary sequence, the gas component disappears leaving room for a dust-dominated environment ...
    • Evidence for a Circumplanetary Disk around Protoplanet PDS 70 b 
      Christiaens, Valentin; Cantalloube, Faustine; Casassus Montero, Simón; Price, Daniel J.; Absil, Olivier; Pinte, Christophe; Girard, Julien; Montesinos, Matias (Institute of Physics Publishing, 2019)
      © 2019. The American Astronomical Society. All rights reserved.We present the first observational evidence for a circumplanetary disk (CPD) around the protoplanet PDS 70 b, based on a new spectrum in the K-band acquired ...
    • Luminous blue variables: An imaging perspective on their binarity and near environment 
      Martayan, Christophe; Lobel, Alex; Baade, Dietrich; Mehner, Andrea; Rivinius, Thomas; Bo n, Henri M. J.; Girard, Julien; Mawet, Dimitri; Montagnier, Guillaume; Blomme, Ronny; Kervella, Pierre; Sana, Hugues; Štefl, Stanislav; Zorec, Juan; Lacour, Sylvestre; Le Bouquin, Jean-Baptiste; Martins, Fabrice; Mérand, Antoine; Patru, Fabien; Selman, Fernando; Frémat, Yves (ESO, 2016-03)
      Context. Luminous blue variables (LBVs) are rare massive stars with very high luminosity. They are characterized by strong photometric and spectroscopic variability related to transient eruptions. The mechanisms at the ...
