Prestellar and protostellar cores in Ori B 9 ⋆
Context. Dense molecular cores are studied in order to gain insight into the processes causing clouds to fragment and form stars. In this study we concentrate on a region which is assumed to represent an early stage of clustered star formation in a giant molecular cloud. Aims. The aims of this study are to determine the properties and spatial distribution of dense cores in the relatively quiesc...
متن کاملMolecular evolution in star-forming cores: From prestellar cores to protostellar cores
We investigate the molecular abundances in protostellar cores by solving the gasgrain chemical reaction network. As a physical model of the core, we adopt a result of onedimensional radiation-hydrodynamics calculation, which follows the contraction of an initially hydrostatic prestellar core to form a protostellar core. Temporal variation of molecular abundances is solved in multiple infalling ...
متن کاملMolecular Evolution and Star Formation: From Prestellar Cores to Protostellar Cores
We investigate molecular evolution in a star-forming core that is initially a hydrostatic starless core and collapses to form a low-mass protostar. The results of a one-dimensional radiation-hydrodynamics calculation are adopted as a physical model of the core. We first derive radii at which CO and large organic species sublimate. CO sublimation in the central region starts shortly before the f...
متن کاملThe dynamical influence of cooling in the envelope of prestellar and protostellar cores
The dynamical influence of cooling in the envelope of prestellar and protostellar cores. Abstract. We compute numerical simulations of spherical collapse triggered by a slow increase in external pressure. We compare isothermal models to models including cooling with a simple but self-consistent treatment of the coupling between gas, grains and radiation field temperatures. The hydrostatic equil...
متن کاملSubmillimeter Studies of Prestellar Cores and Protostars: Probing the Initial Conditions for Protostellar Collapse
Improving our understanding of the initial conditions and earliest stages of protostellar collapse is crucial to gain insight into the origin of stellar masses, multiple systems, and protoplanetary disks. Observationally, there are two complementary approaches to this problem: (1) studying the structure and kinematics of prestellar cores observed prior to protostar formation, and (2) studying t...
