On the Spatial Distribution of Stellar Populations in the Large Magellanic Cloud
We measure the angular correlation function of stars in a region of the Large Magellanic Cloud (LMC) that spans 2.0◦ × 1.5◦. We find that the correlation functions of stellar populations are represented well by exponential functions of the angular separation for separations between 2 and 40 arcmin (corresponding to ∼ 30 pc and 550 pc for an LMC distance of 50 kpc). The inner boundary is set by ...
متن کاملDust and Stellar Populations in the Large Magellanic Cloud
We present an analysis of line-of-sight extinction measurements obtained using data from the Magellanic Clouds Photometric Survey (Zaritsky, Harris, & Thompson 1997, AJ, 114, 1002), which provides 4-filter photometry for millions of stars in the Large Magellanic Cloud. We find that visual extinctions are typically larger by several tenths of a magnitude for stars with effective temperatures > 1...
متن کاملStellar Populations in the Large Magellanic Cloud from 2MASS
We present a morphological analysis of the feature-rich 2MASS LMC colormagnitude diagram, identifying Galactic and LMC populations and estimating the density of LMC populations alone. We also present the projected spatial distributions of various stellar populations. The conditions that prevailed when 2MASS observed the LMC provided 10σ limiting sensitivity for J <∼ 16.3, H <∼ 15.3, Ks <∼ 14.7....
متن کاملthe effect of traffic density on the accident externality from driving the case study of tehran
در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولThe Magellanic Clouds Photometric Survey: the Large Magellanic Cloud Stellar Catalog and Extinction Map
We present our catalog of U , B, V , and I stellar photometry of the central 64 deg area of the Large Magellanic Cloud. Internal and external astrometric and photometric tests using existing optical photometry (U , B, and V from Massey’s bright star catalog and I from the near-infrared sky survey DENIS) are used to confirm our observational uncertainty estimates. We fit stellar atmosphere model...
