    • 3D radiative transfer of intrinsically polarized dust emission based on aligned aspherical grains 
      Bertrang, Gesa H.-M.; Wolf, S. (Oxford University Pres, 2017)
      (Sub-)millimetre observations of the polarized emission of aligned aspherical dust grains enable us to study the magnetic fields within protoplanetary disc. However, the interpretation of these observations is complex. One ...
    • Gap, shadows, spirals, and streamers: SPHERE observations of binary-disk interactions in GG Tauri A 
      Keppler, M.; Penzlin, A.; Benisty, Myriam; van Boekel, R.; Henning, T.; Van Holstein, R. G.; Kley, W.; Garufi, A.; Ginski, C.; Brandner, W.; Bertrang, Gesa H. M.; Boccaletti, A.; de Boer, J.; Bonavita, M.; Brown Sevilla, S.; Chauvin, Gael Epely; Dominik, C.; Janson, M.; Langlois, M.; Lodato, G.; Maire, A. L.; Ménard, F.; Pantin, E.; Pinte, C.; Stolker, T.; Szulágyi, J.; Thebault, P.; Villenave, M.; Zurlo, A.; Rabou, P.; Feautrier, P.; Feautrier, P.; Feldt, M.; Madec, F.; Wildi, F. (EDP Science, 2020)
      Context. A large portion of stars is found to be part of binary or higher-order multiple systems. The ubiquity of planets found around single stars raises the question of whether and how planets in binary systems form. ...
    • Magnetic fields in protoplanetary discs: from MHD simulations to ALMA observations 
      Bertrang, Gesa; Flock, M.; Wolf, S. (Oxford University Press, 2017-01)
      Magnetic fields significantly influence the evolution of protoplanetary discs and the formation of planets, following the predictions of numerous magnetohydrodynamic (MHD) simulations. However, these predictions are yet ...
    • Orbits in the T Tauri triple system observed with SPHERE 
      Köhler, R.; Kasper, M.; Herbst, T. M.; Ratzka, T.; Bertrang, Gesa H.-M. (ESO, 2016-03)
      Aims. We present new astrometric measurements of the components in the T Tauri system and derive new orbits and masses. Methods. T Tauri was observed during the science verification time of the new extreme adaptive ...
    • Radiation hydrodynamical turbulence in protoplanetary disks: Numerical models and observational constraints 
      Flock, Mario; Nelson, Richard P.; Turner, Neal J.; Bertrang, Gesa H.-M.; Carrasco González, Carlos; Henning, Thomas; Lyra, Wladimir; Teague, Richard (IOP Publishing Ltd, 2017)
      Planets are born in protostellar disks, which are now observed with enough resolution to address questions about internal gas flows. Magnetic forces are possibly drivers of the flows, but ionization state estimates suggest ...
