Star Formation in the Orion-monoceros Complex
Pre-main sequence stars in the Orion-Monoceros Complex are either distributed in groups closed associated with dense cores, or dispersed along molecular filaments. Some molecular clouds are apparently affected by the OrionEridanus Superbubble created by the Wolf-Rayet winds and supernovae from the OriOB1 association, whose shock fronts compressed and triggered starbirth in adjacent molecular cl...
متن کاملTesting Massive Star Formation Theory in Orion
I compare theoretical models of massive star formation with observations of the Orion Hot Core, which harbors one of the closest massive protostars. Although this region is complicated, many of its features (size, luminosity, accretion disk, H II region, outflow) may be understood by starting with a simple model in which the star forms from a massive gas core that is a coherent entity in approx...
متن کاملStar Formation in Space and Time: the Orion Nebula Cluster
We examine the pattern of star birth in the Orion Nebula cluster (ONC), with the goal of discerning the cluster’s formation mechanism. Outside the Trapezium, the distribution of stellar masses is remarkably uniform and is not accurately described by the field-star initial mass function. The deconvolved, three-dimensional density of cluster members peaks at the Trapezium stars, which are truly a...
متن کاملStar Formation in the Orion Nebula I : Stellar Content
The Orion Nebula is one of the most frequently observed nearby (< 1 kiloparsec) star forming regions and, consequently, the subject of a large bibliography of observations and interpretation. The summary in this chapter is bounded spatially by the blister HII region, with sources beyond the central nebula that are part of the same dynamical clustering covered in other chapters in this book. Her...
متن کاملThe Far-ir View of Sgr B2 and Orion Kl: Template Star-forming Regions
We summarize the main highlights from ISO observations towards Sgr B2 and Orion KL in the far–IR domain (∼43 to 197μm). Both Star–Forming Regions are among the best sources to construct a template for more distant and unresolved regions (e.g., extragalactic). We stress some peculiarities in the interpretation (excitation and radiative transfer) of far–IR spectral lines and dust continuum emission.
