Gas kinematics around filamentary structures in the Orion B cloud
Mathilde Gaudel, Jan H. Orkisz, Maryvonne Gerin +27
Understanding the initial properties of star-forming material and how they affect the star formation process is key. From an observational point of view, the feedback from young hi…
Non-ideal self-gravity and cosmology: the importance of correlations in the dynamics of the large-scale structures of the Universe
P. Tremblin, G. Chabrier, T. Padioleau +1
Inspired by the statistical mechanics of an ensemble of interacting particles (BBGKY hierarchy), we propose to account for small-scale inhomogeneities in self-gravitating astrophys…
A dynamically young, gravitationally stable network of filaments in Orion B
Jan H. Orkisz, Nicolas Peretto, Jérôme Pety +15
Filaments are a key step on the path that leads from molecular clouds to star formation. However, their characteristics are heavily debated, and the exact processes that lead to th…
Impact of galactic shear and stellar feedback on star formation
Cédric Colling, Patrick Hennebelle, Sam Geen +2
A numerical shearing box is used to perform three-dimensional simulations of a 1 kpc stratified cubic box of turbulent and self-gravitating interstellar medium (in a rotating frame…
Clustering the Orion B giant molecular cloud based on its molecular emission
Emeric Bron, Chloé Daudon, Jérôme Pety +12
Previous attempts at segmenting molecular line maps of molecular clouds have focused on using position-position-velocity data cubes of a single line to separate the spatial compone…
Spatial distribution of star formation related to ionized regions throughout the inner Galactic plane
P. Palmeirim, A. Zavagno, D. Elia +35
We present a comprehensive statistical analysis of star-forming objects located in the vicinities of 1 360 bubble structures throughout the Galactic Plane and their local environme…
