    • ALMA reveals a large structured disk and nested rotating outflows in DG Tauri B 
      De Valon, A.; Dougados, C.; Cabrit, S.; Louvet, F.; Zapata, L. A.; Mardones, D. (EDP Sciences, 2020)
      We present Atacama Large Millimeter Array (ALMA) Band 6 observations at 14-20 au spatial resolution of the disk and CO(2-1) outflow around the Class I protostar DG Tau B in Taurus. The disk is very large, both in dust ...
    • Dusty spirals triggered by shadows in transition discs 
      Cuello, N.; Montesinos, M.; Stammler, S. M.; Louvet, F.; Cuadra, J. (EDP Sciences, 2019)
      Context. Despite the recent discovery of spiral-shaped features in protoplanetary discs in the near-infrared and millimetre wavelengths, there is still an active discussion to understand how they formed. In fact, the spiral ...
    • Episodic accretion constrained by a rich cluster of outflows 
      Nony, T.; Motte, F.; Louvet, F.; Plunkett, A.; Gusdorf, A.; Fechtenbaum, S.; Pouteau, Y.; Lefloch, B.; Bontemps, S.; Molet, J.; Robitaille, J-F (EDP Sciences, 2020)
      Context. The accretion history of protostars remains widely mysterious, even though it represents one of the best ways to understand the protostellar collapse that leads to the formation of stars.Aims. Molecular outflows, ...
    • Lack of high-mass pre-stellar cores in the starless MDCs of NGC 6334 
      Louvet, F.; Neupane, S.; Garay Brignardello, Guido; Russeil, D.; Zavagno, A.; Guzman, A.; Gomez, L.; Bronfman Aguiló, Leonardo; Nony, T. (EDP Sciences, 2019)
      Context. The formation of high-mass stars remains unknown in many aspects. There are two competing families of models to explain the formation of high-mass stars. On the one hand, quasi-static models predict the existence ...
    • Large scale map of millimeter wavelength hydrogen radio recombination lines around a young massive star cluster 
      Nguyen Lu'o'ng, Q.; Anderson, L. D.; Motte, F.; Louvet, F.; Bronfman Aguiló, Leonardo (IOP Publishing Ltd, 2017)
      We report the first map of large-scale (10 pc in length) emission of millimeter-wavelength hydrogen recombination lines (mm-RRLs) toward the giant H II region around the W43-Main young massive star cluster (YMC). Our mm-RRL ...
    • Observations of edge-on protoplanetary disks with ALMA I. Results from continuum data 
      Villenave, M.; Menard, F.; Dent, W. R. F.; Duchene, G.; Stapelfeldt, K. R.; Benisty, M.; Boehler, Y.; Van der Plas, G.; Pinte, C.; Telkamp, Z.; Wolff, S.; Flores, C.; Lesur, G.; Louvet, F.; Riols, A.; Dougados, C.; Williams, H.; Padgett, D. (EDP, 2020)
      Aims. We aim to study vertical settling and radial drift of dust in protoplanetary disks from a different perspective: an edge-on view. An estimation of the amplitude of settling and drift is highly relevant to understanding ...
    • Outflows, cores, and magnetic field orientations in W43-MM1 as seen by ALMA 
      Arce Tord, C.; Louvet, F.; Cortés, P. C.; Motte, F.; Hull, C. L. H.; Le Gouellec, V. J. M.; Garay, G.; Nony, T.; Didelon, P.; Bronfman Aguiló, Leonardo (EDP Sciences, 2020)
      Aims. It has been proposed that the magnetic field, which is pervasive in the interstellar medium, plays an important role in the process of massive star formation. To better understand the impact of the magnetic field at ...
    • The earliest phases of high mass star formation, as seen in NGC 6334 by Herschel HOBYS 
      Tige, J.; Motte, F.; Russeil, D.; Louvet, F. (EDP Sciences, 2017)
      Aims. To constrain models of high-mass star formation, the Herschel-HOBYS key program aims at discovering massive dense cores (MDCs) able to host the high-mass analogs of low-mass prestellar cores, which have been searched ...
    • The unexpectedly large proportion of high-mass starforming cores in a Galactic mini-starburst 
      Motte, F.; Nomy, T.; Louvet, F.; Marsh, K.A.; Bontemps, S.; Whitworth, A. P.; Men’shchikov, A.; Nguyen Luong6, Q.; Csengeri, T.; Maury, A. J.; Gusdorf, A.; Chapillon, E.; Könyves, V.; Schilke, P.; Duarte Cabral, A.; Didelon, P.; Gaudel, M. (Springer Nature, 2018)
      Understanding the processes that determine the stellar Initial Mass Function (IMF) is a critical unsolved problem, with profound implications for many areas of astrophysics1. In molecular clouds, stars are formed in cores, ...
