Proper Motions of Thermal Radio Sources near Hh 7-11 in the Ngc 1333 Star Forming Region
Star forming regions are expected to show linear proper motions due to the relative motion of the Sun with respect to the region. These proper motions appear superposed to the proper motions expected in features associated with mass ejection from the young stellar objects embedded in them. Therefore, it is necessary to have a good knowledge of the proper motions of the region as a whole in orde...
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 اولTrigonometric Parallaxes of Massive Star Forming Regions : II . Cep A & NGC 7538
We report trigonometric parallaxes for the sources NGC 7538 and Cep A, corresponding to distances of 2.65 −0.11 kpc and 0.70 +0.04 −0.04 kpc, respectively. The distance to NGC 7538 is considerably smaller than its kinematic distance and places it in the Perseus spiral arm. The distance to Cep A is also smaller than its kinematic distance and places it in the “Local” arm or spur. Combining the d...
متن کاملA Near-infrared Study of the Ngc 7538 Star-forming Region
We present subarcsecond (FWHM 0B7), near-infrared (NIR) JHKs-band images and a high-sensitivity radio continuum image at 1280 MHz, using SIRIUS on the University of Hawaii 88 inch (2.2 m) telescope and the Giant Metrewave Radio Telescope (GMRT). The NIR survey covers an area of 24 arcmin with 10 limiting magnitudes of 19.5, 18.4, and 17.3 in the J, H, and Ks bands, respectively. Our NIR images ...
متن کامل0 A Submillimeter Study of the Star - Forming Region NGC 7129
We present new molecular (CO J=3−2) and dust continuum (450 μm and 850 μm) maps of the NGC7129 star forming region. The maps include the Herbig Ae/Be star LkHα 234, the far-infrared source NGC 7129 FIRS2 and several other pre-stellar sources embedded within the molecular ridge. We also obtained CO J=3−2 spectra at several positions within the mapped region. Both the continuum and CO emissions s...
