The Embedded Massive Star Forming Region RCW 38
RCW 38 is a uniquely young (<1 Myr), embedded (AV ∼ 10) stellar cluster surrounding a pair of early O stars (∼O5.5) and is one of the few regions within 2 kpc other than Orion to contain over 1000 members. X-ray and deep near-infrared observations reveal a dense cluster with over 200 X-ray sources and 400 infrared sources embedded in a diffuse hot plasma within a 1 pc diameter. The central O st...
متن کاملThe Suzaku Observation of RCW 86 Northeastern Shell
This paper reports the Suzaku results on the northeast shell of RCW 86. With the spatial and spectral analysis, we separated the X-rays into three distinct components; low (kTe ∼0.3 keV) and high (kTe ∼1.8 keV) temperature plasmas and a non-thermal component, and discovered their spatial distributions are different from each other. The low temperature plasma is dominated at the east rim, wherea...
متن کاملSuzaku Observation of the RCW 86 Northeastern Shell
This paper reports on Suzaku results concerning the northeast shell of RCW 86. With both spatial and spectral analyses, we separated the X-rays into three distinct components: low (kTe ∼0.3 keV) and high (kTe ∼1.8 keV) temperature plasmas and a non-thermal component, and discovered that their spatial distributions are different from each other. The low-temperature plasma is dominated at the eas...
متن کاملHydrogen Stark broadened Brackett lines
Stark broadened lines of the hydrogen Brackett series are computed for the conditions of stellar atmospheres and circumstellar envelopes. The computation is performed within the Model Micro eld Method, which includes the ion dynamic e ects and makes the bridge between the impact limit at low density and the static limit at high density and in the line wings. The computation gives the area norma...
متن کاملH 107 a Recombination - Line Emission , 4800 - MHz and 1666 - MHz Continuum Emission in the HI Region RCW 38
We present results from observations of H107a recombination-line emission and the related 4800 MHz continuum emission of the HII region RCW 38 using the Australia Telescope Compact Array. We find the continuum emission to be concentrated in a ring-like structure with the 05 star, IRS2, approximately centered in the cavity within the ring. The temperature of the ionized gas ranges from 5200 to 7...
