    • 3D shape of Orion A from Gaia DR2 

      Grossschedl, Josefa E.; Alves, Joao; Meingast, Stefan; Ackerl, Christine; Ascenso, Joana; Bouy, Herve; Burkert, Andreas; Forbrich, Jan; Fuernkranz, Verena; Goodman, Alyssa; Hacar, Alvaro; Herbst-Kiss, Gabor; Lada, Charles J.; Larreina, Irati; Leschinski, Kieran; Lombardi, Marco; Moitinho, Andre; Mortimer, Daniel; Zari, Eleonora (2018-11-14)
      We use the Gaia DR2 distances of about 700 mid-infrared selected young stellar objects in the benchmark giant molecular cloud Orion A to infer its 3D shape and orientation. We find that Orion A is not the fairly straight ...

    • The HP2 Survey - IV. The Pipe nebula : Effective dust temperatures in dense cores 

      Hasenberger, Birgit; Lombardi, Marco; Alves, João; Forbrich, Jan; Hacar, Alvaro; Lada, Charles J. (2018-12-01)
      Multi-wavelength observations in the sub-millimeter regime provide information on the distribution of both the dust column density and the effective dust temperature in molecular clouds. In this study, we created high-resolution ...

    • Smoke in the Pipe Nebula: dust emission and grain growth in the starless core FeSt 1-457 

      Forbrich, Jan; Lada, Charles J.; Lombardi, Marco; Roman-Zuñiga, Carlos; Alves, João (2015-08-13)
      (abridged) Methods: We derive maps of submillimeter dust optical depth and effective dust temperature from Herschel data that were calibrated against Planck. After calibration, we then fit a modified blackbody to the ...

    • Some like it cold: molecular emission and effective dust temperatures of dense cores in the Pipe Nebula 

      Forbrich, Jan; Öberg, Karin; Lada, Charles J.; Lombardi, Marco; Hacar, Alvaro; Alves, João; Rathborne, Jill M. (2014-08-08)
      Aims. The Pipe Nebula is characterized by a low star-formation rate and is therefore an ideal environment to explore how initial conditions, including core characteristics, affect star-formation efficiencies. Methods. In ...

    • VISION - Vienna survey in Orion I. VISTA Orion A Survey 

      Meingast, Stefan; Alves, João; Mardones, Diego; Teixeira, Paula; Lombardi, Marco; Großschedl, Josefa; Ascenso, Joana; Bouy, Herve; Forbrich, Jan; Goodman, Alyssa; Hacar, Alvaro; Hasenberger, Birgit; Kainulainen, Jouni; Kubiak, Karolina; Lada, Charles; Lada, Elizabeth; Moitinho, André; Petr-Gotzens, Monika; Rodrigues, Lara; Román-Zúñiga, Carlos G. (2016-03-07)
      Orion A hosts the nearest massive star factory, thus offering a unique opportunity to resolve the processes connected with the formation of both low- and high-mass stars. Here we present the most detailed and sensitive ...

    • VISION - Vienna survey in Orion. III. Young stellar objects in Orion A 

      Großschedl, Josefa E.; Alves, João; Teixeira, Paula S.; Bouy, Hervé; Forbrich, Jan; Lada, Charles J.; Meingast, Stefan; Hacar, Álvaro; Ascenso, Joana; Ackerl, Christine; Hasenberger, Birgit; Köhler, Rainer; Kubiak, Karolina; Larreina, Irati; Linhardt, Lorenz; Lombardi, Marco; Möller, Torsten (2018-09-30)
      We extend and refine the existing young stellar object (YSO) catalogs for the Orion A molecular cloud, the closest massive star-forming region to Earth. This updated catalog is driven by the large spatial coverage (18.3 ...

    • VISIONS: The VISTA Star Formation Atlas 

      Meingast, Stefan; Alves, João; Bouy, Hervé; Petr-Gotzens, Monika G.; Fürnkranz, Verena; Großschedl, Josefa E.; Hernandez, David; Rottensteiner, Alena; Arnaboldi, Magda; Ascenso, Joana; Bayo, Amelia; Brändli, Erik; Brown, Anthony G. A.; Forbrich, Jan; Goodman, Alyssa; Hacar, Alvaro; Hasenberger, Birgit; Köhler, Rainer; Kubiak, Karolina; Kuhn, Michael; Lada, Charles; Leschinski, Kieran; Lombardi, Marco; Mardones, Diego; Mascetti, Laura; Miret-Roig, Núria; Moitinho, André; Mužic, Koraljka; Piecka, Martin; Posch, Laura; Prusti, Timo; Ramírez, Karla Peña; Ramlau, Ronny; Ratzenböck, Sebastian; Sacco, Germano; Swiggum, Cameren; Teixeira, Paula Stella; Urban, Vanessa; Zari, Eleonora; Zucker, Catherine (2023-05-31)
      VISIONS is an ESO public survey of five nearby (d < 500 pc) star-forming molecular cloud complexes that are canonically associated with the constellations of Chamaeleon, Corona Australis, Lupus, Ophiuchus, and Orion. The ...
