Journal ArticleDOI
On the Structure of the Orion A Cloud and the Formation of the Orion Nebula Cluster
Lee Hartmann,Andreas Burkert +1 more
TL;DR: In this paper, the Orion A cloud is gravitationally collapsing on large scales, and is producing the Orion Nebula Cluster through the focusing effects of gravity acting within a finite cloud geometry.
Journal ArticleDOI
Model scattering envelopes of young stellar objects. II - Infalling envelopes
Barbara A. Whitney,Lee Hartmann +1 more
TL;DR: In this paper, the authors present scattered light images for models of young stellar objects surrounded by dusty envelopes, where the envelopes are assumed to have finite angular momentum and are falling in steady flow onto a disk.
Journal ArticleDOI
2-D simulations of FU Orionis disk outbursts
TL;DR: In this paper, a two-dimensional, axisymmetric model incorporating full vertical structure with a new treatment of the radiative boundary condition for the disk photosphere was developed to explore the physical properties of protostellar disks.
Journal ArticleDOI
Kinematic structure of the orion nebula cluster and its surroundings
Gábor Fűrész,Gábor Fűrész,Lee Hartmann,S. Thomas Megeath,Andrew Szentgyorgyi,Erika T. Hamden +5 more
TL;DR: In this paper, high-resolution spectra of 1215 stars in the Orion Nebula Cluster (ONC) and the surrounding Orion 1c association, obtained with the Hectochelle multiobject echelle spectrograph on the 6.5 m MMT, were used to confirm 1111 stars as members, based on their radial velocity and/or Hα emission.
Journal ArticleDOI
Comments on Inferences of Star Formation Histories and Birth Lines
TL;DR: The Palla and Stahler picture implies that most molecular clouds should have extremely low rates of star formation and that in such inactive stages, the stellar initial mass function (IMF) should be strongly skewed toward producing stars with masses 1 M☉; neither prediction is supported by observations as discussed by the authors.
