    • 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 ...

    • Gas absorption and dust extinction towards the Orion Nebula Cluster 

      Hasenberger, Birgit; Forbrich, Jan; Alves, Joao; Wolk, Scott; Meingast, Stefan; Getman, Konstantin; Pillitteri, Ignazio (2016-08-29)
      We characterise the relation between the gas and dust content of the interstellar medium towards young stellar objects in the Orion Nebula Cluster. X-ray observations provide estimates of the absorbing equivalent hydrogen ...
