    • A direct imaging survey of spitzer-detected debris disks: occurrence of giant planets in dusty systems 
      Meshkat, Tiffany; Mawet, Dimitri; Bryan, Marta L.; Hinkley, Sasha; Bowler, Brendan P.; Stapelfeldt, Karl R.; Batygin, Konstantin; Padgett, Deborah; Morales, Farisa Y.; Serabyn, Eugene; Christiaens, Valentin; Brandt, Timothy D.; Wahhaj, Zahed (IOP Publishing Ltd., 2017)
      We describe a joint high-contrast imaging survey for planets at the Keck and Very Large Telescope of the last large sample of debris disks identified by the Spitzer Space Telescope. No new substellar companions were ...
    • Deep Exploration of Eridani with Keck Ms-band Vortex Coronagraphy and Radial Velocities: Mass and Orbital ... 
      Mawet, Dimitri; Hirsch, Lea; Lee, Eve J.; Ruffio, Jean Baptiste; Bottom, Michael; Fulton, Benjamin J.; Absil, Olivier; Beichman, Charles; Bowler, Brendan; Bryan, Marta; Choquet, Elodie; Ciardi, David; Christiaens, Valentin; Defrère, Denis; Gómez González, Carlos (Institute of Physics Publishing, 2019)
      We present the most sensitive direct imaging and radial velocity (RV) exploration of Eridani to date. Eridani is an adolescent planetary system, reminiscent of the early solar system. It is surrounded by a prominent and ...
    • Dynamical evidence of a spiral arm–driving planet in the MWC 758 protoplanetary disk 
      Ren, Bin; Dong, Ruobing; van Holstein, Rob G.; Ruffio, Jean Baptiste; Calvin, Benjamín A.; Girard, Julien H.; Benisty, Myriam; Boccaletti, Anthony; Espósito, Thomas M.; Choquet, Elodie; Mawet, Dimitri; Pueyo, Laurent; Stolker, Tomas; Chiang, Eugene; de Boer, Jozua; Debes, John H.; Garufi, Antonio; Grady, Carol A.; Hines, Dean C.; Maire, Anne-Lise; Menard, Francoise; Millar-Blanchaer, Maxell A.; Perrin, Marshall D.; Poteet, Charles A.; Schneider, Glenn (IOP, 2020)
      More than a dozen young stars host spiral arms in their surrounding protoplanetary disks. The excitation mechanisms of such arms are under debate. The two leading hypotheses-companion-disk interaction and gravitational ...
    • 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 ...
    • VIP: Vortex Image Processing package for high-contrast direct imaging 
      Gómez González, Carlos; Wertz, Olivier; Absil, Olivier; Christiaens, Valentin; Defrere, Denis; Mawet, Dimitri; Milli, Julien; Absil, Pierre Antoine; Van Droogenbroeck, Marc; Cantalloube, Faustine; Philip, Hinz; Skemer, Andrew J.; Karlsson, Mikael; Surdej, Jean (IOP Publishing Ltd., 2017)
      We present the Vortex Image Processing (VIP) library, a python package dedicated to astronomical high-contrast imaging. Our package relies on the extensive python stack of scientific libraries and aims to provide a flexible ...
