The Monoceros R2 Molecular Cloud
The Monoceros R2 region was first recognized as a chain of reflection nebulae illuminated by Aand B-type stars. These nebulae are associated with a giant molecular cloud that is one of the closest massive star forming regions to the Sun. This chapter reviews the properties of the Mon R2 region, including the namesake reflection nebulae, the large scale molecular cloud, global star formation act...
متن کاملGamma-ray bursts in normal and extreme star-forming galaxies
We discuss how gamma-ray burst (GRB) optical afterglows and multiwavelength observations of their host galaxies can be used to obtain information about the relative amounts of star formation happening in optical and submillimetre galaxies. That such an analysis will be possible follows from the currently-favoured idea that GRBs are closely linked with high-mass star formation. Studying GRB host...
متن کاملAre Gamma-Ray Bursts in Star Forming Regions?
The optical afterglow of the gamma-ray burst GRB 970508 (z = 0.835) was a few hundred times more luminous than any supernova. Therefore, a name ‘hypernova’ is proposed for the whole GRB/afterglow event. There is tentative evidence that the GRBs: 970228, 970508, and 970828 were close to star forming regions. If this case is strengthened with future afterglows then the popular model in which GRBs...
متن کاملUltraluminous X-ray Source Correlations with Star-forming Regions
Maps of low-inclination nearby galaxies in Sloan Digitized Sky Survey u − g, g − r and r − i colors are used to determine whether Ultraluminous X-ray sources (ULXs) are predominantly associated with star-forming regions of their host galaxies. An empirical selection criterion is derived from colors of H ii regions in M81 and M101 that differentiates between the young, blue stellar component and...
متن کاملThe Orion Star-Forming Region
General properties of the Orion star-forming region are discussed, with a focus on the dense Orion Nebula Cluster (ONC). This cluster contains between 2500 and 4500 objects located within a few parsecs of the eponymous Trapezium stars. Its members are aged <1 to a few Myr and encompass the full spectrum of stellar masses <50 M⊙, as well as brown dwarfs detected with masses as low as <0.02 M⊙ (2...
