The Primordial Abundance of He: An Update
We include new data in an updated analysis of helium in low metallicity extragalactic H II regions with the goal of deriving the primordial abundance of He (YP). We show that the new observations of Izotov et al. (ITL) are consistent with previous data. However they should not be taken in isolation to determine YP due to the lack of sufficiently low metallicity points. We use the extant data in...
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...
15 صفحه اولSystematic uncertainties in the determination of the primordial 4 He abundance
The primordial helium abundance Yp is commonly inferred from abundance determinations in lowmetallicity extragalactic H ii-regions. Such determinations may be subject to systematic uncertainties that are investigated here. Particular attention is paid to two effects: icf -corrections for “imperfect” ionization structure leading to significant amounts of (unobservable) neutral helium or hydrogen...
متن کاملBayesian sample size Determination Using a Scaled Exponential Utility Function According to Numerical Method
In this paper we propose a utility function and obtain the Bayese stimate and the optimum sample size under this utility function. This utility function is designed especially to obtain the Bayes estimate when the posterior follows a gamma distribution. We consider a Normal with known mean, a Pareto, an Exponential and a Poisson distribution for an optimum sample size under the propose...
متن کاملNEW DETREMINATION METHOD OF PRIMORDIAL Li ABUNDANCE
We discuss the primordial nucleosynthesis in lepton asymmetric Universe models. In order to better estimate the universal baryonmass density parameter Ωb, we try to remove the uncertainty from the theoretical prediction of primordial Li abundance. We propose a new method to determine the primordial Li by the use of isotopic abundance ratio Li/Li in the interstellar medium which exhibits the min...
