    • 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 ...
    • Size and structures of disks around very low mass stars in the taurus star-forming region 
      Kurtovic, N. T.; Pinilla, P.; Long, F.; Benisty, Myriam; Manara, C. F.; Natta, A.; Pascucci, I.; Ricci, L.; Scholz, A.; Testi, L. (EDP Sciences, 2021)
      Context. The discovery of giant planets orbiting very low mass stars (VLMS) and the recent observed substructures in disks around VLMS is challenging planet formation models. Specifically, radial drift of dust particles ...
    • Spiral waves triggered by shadows in transition disks 
      Montesinos, Matías; Pérez, Sebastián; Casassus Montero, Simón; Marino, Sebastián; Cuadra, Jorge; Christiaens, Valentín (IOP Publishing, 2016)
      Circumstellar asymmetries such as central warps have recently been shown to cast shadows on outer disks. We investigate the hydrodynamical consequences of such variable illumination on the outer regions of a transition ...
    • The Gaia -ESO Survey: Age spread in the star forming region NGC 6530 from the HR diagram and gravity indicators 
      Prisinzano, L.; Damiani, F.; Kalari, V.; Jeffries, R.; Bonito, R.; Micela, G.; Wright, N. J.; Jackson, R. J.; Tognelli, E.; Guarcello, M. G.; Vink, J. S.; Klutsch, A.; Jiménez-Esteban, F. M.; Roccatagliata, V.; Tautvaišiene, G.; Gilmore, G.; Randich, S.; Alfaro, E. J.; Fla (EDP Sciences, 2019)
      Context. In very young clusters, stellar age distribution is empirical proof of the duration of star cluster formation and thus it gives indications of the physical mechanisms involved in the star formation process. ...
    • The GRAVITY young stellar object survey: IV. The CO overtone emission in 51 Oph at sub-au scales 
      Koutoulaki, M.; García López, R.; Natta, A.; Fedriani, R.; Garatti, A. Caratti O.; Ray, T. P.; Coffey, D.; Brandner, W.; Dougados, C.; García, P. J. V.; Klarmann, L.; Labadie, L.; Perraut, K.; Sánchez Bermúdez, J.; Lin, C. C.; Amorim, A.; Bauböck, M.; Benisty, Myriam; Berger, J. P.; Buron, A.; Caselli, P.; Clénet, Y.; Coudé Du Foresto, V.; De Zeeuw, P. T.; Duvert, G.; De Wit, W.; Eckart, A.; Eisenhauer, F.; Filho, M.; Gao, F.; Gendron, E.; Genzel, R.; Gillessen, S.; Grellmann, R.; Habibi, M.; Haubois, X.; Haussmann, F.; Henning, T.; Hippler, S.; Hubert, Z.; Horrobin, M.; Jiménez Rosales, A.; Jocou, L.; Kervella, P.; Kolb, J.; Lacour, S.; Le Bouquin, J. B.; Léna, P.; Linz, H.; Ott, T.; Paumard, T.; Perrin, G.; Pfuhl, O.; Ramírez Tannus, M. C.; Rau, C.; Rousset, G.; Scheithauer, S.; Shangguan, J.; Stadler, J.; Straub, O.; Straubmeier, C.; Sturm, E.; Van Dishoeck, E.; Vincent, F.; Von Fellenberg, S.; Widmann, F.; Wieprecht, E.; Wiest, M.; Wiezorrek, E.; Yazici, S.; Zins, G. (EDP Sciences, 2021)
      Context. 51 Oph is a Herbig Ae/Be star that exhibits strong near-infrared CO ro-vibrational emission at 2.3 mu m, most likely originating in the innermost regions of a circumstellar disc.Aims. We aim to obtain the physical ...
    • The VLA/ALMA nascent disk and multiplicity (VANDAM) survey of Orion protostars. A statistical characterization ... 
      Tobin, John; Sheehan, Patrick; Megeath, S. Thomas; Díaz Rodríguez, Ana; Offner, Stella; Murillo, Nadia; Van 't Hoff, Merel; Van Dishoeck, Ewine; Osorio, Mayra; Anglada, Guillem; Furlan, Elise; Stutz, Amelia; Reynolds, Nickalas; Karnath, Nicole; Fischer, William; Persson, Magnus; Looney, Leslie; Li, Zhi-Yun; Stephens, Ian; Chandler, Claire; Cox, Erin; Dunham, Michael; Tychoniec, Lukasz; Kama, Mihkel; Kratter, Kaitlin; Kounkel, Marina; Mazur, Brian; Maud, Luke; Patel, Lisa; Pérez, Laura; Sadavoy, Sarah; Segura Cox, Dominique; Sharma, Rajeeb; Stephenson, Brian; Watson, Dan; Wyrowski, Friedrich (IOP Publishing, 2020)
      We have conducted a survey of 328 protostars in the Orion molecular clouds with the Atacama Large Millimeter/submillimeter Array at 0.87 mm at a resolution of similar to 0.'' (40au), including observations with the Very ...
