The initial conditions of stellar protocluster formation
Context. The majority of stars form in clusters. Therefore a comprehensive view of star formation requires understanding the initial conditions for cluster formation. Aims. The goal of our study is to shed light on the physical properties of infrared dark clouds (IRDCs) and the role they play in the formation of stellar clusters. This article, the first of a series dedicated to the study of IRD...

متن کاملThe initial conditions for stellar protocluster formation - III. The Herschel counterparts of the Spitzer Dark Cloud catalogue
Context. Galactic plane surveys of pristine molecular clouds are key for establishing a Galactic-scale view of star formation. For this reason, an unbiased sample of infrared dark clouds in the 10◦ < |l| < 65◦, |b| < 1◦ region of the Galactic plane was built using Spitzer 8 μm extinction. However, intrinsic fluctuations in the mid-infrared background can be misinterpreted as foreground clouds. ...
متن کاملThe Initial Conditions of Stellar Protocluster Formation III. The Herschel counterparts of the Spitzer Dark Cloud catalogue
Context. Galactic plane surveys of pristine molecular clouds are key for establishing a Galactic-scale view of the earliest stages of star formation. For this reason Peretto & Fuller (2009; hereafter PF09) built an unbiased sample of Infrared Dark Clouds (IRDCs) in the 10◦ < |l| < 65◦, |b| < 1◦ region of the Galactic plane using Spitzer 8μm extinction. However, in absorption studies, intrinsic ...
متن کاملThe initial conditions of star formation in the Ophiuchus main cloud: Kinematics of the protocluster condensations
Context. The earliest phases of clustered star formation and the origin of the stellar initial mass function (IMF) are currently much debated. In one school of thought the IMF of embedded clusters is entirely determined by turbulent fragmentation at the prestellar stage of star formation, while in a major alternative view it results from dynamical interactions and competitive accretion at the p...
