Spectroscopic monitoring of the luminous blue variable Westerlund1-243 from 2002 to 2009
Context. The massive post-main sequence star W243 in the galactic starburst cluster Westerlund 1 has undergone a spectral transformation from a B2Ia supergiant devoid of emission features in 1981 to an A-type supergiant with a rich emission-line spectrum by 2002/03. Aims. We examine the continued evolution of W243 from 2002 to 2009 to understand its evolutionary state, current physical properti...

متن کاملA spectroscopic analysis of the Luminous Blue Variable candidate WRA 751 ?
We present spectroscopic observations of the LBV candidate WRA 751 taken at different epochs during the period 1989−1995. These observations are used to monitor the temporal evolution of the spectrum over the last few years. In addition, we identify most of the emission and absorption features in the spectral range 4100−9250 Å and obtain a new determination of the extinction towards this source...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
