Velorum: Orbital Solution and Fundamental Parameter Determination with SUSI
The first complete orbital solution for the double-lined spectroscopic binary system γ 2 Velorum, obtained from measurements with the Sydney University Stellar Interferometer (SUSI), is presented. This system contains the closest example of a Wolf-Rayet star and the promise of full characterisation of the basic properties of this exotic highmass system has subjected it to intense study as an ar...
متن کاملThe orbital motion of γ2 Velorum
We analyze the orbital motion of γ2 Velorum based on high resolution optical spectra obtained in 1995 and 1996. By combining our data with values from the literature we find a period P = 78.53± 0.01 d. We determine radial velocity semiamplitudesKWR = 122± 2 km s−1 andKO = 38.4± 2 km s−1 for the Wolf-Rayet star and the O star, respectively. The given errors are the standard deviations of the res...

در این پایان نامه روش جدیدی مبتنی بر روش حل معادلات دیفرانسیل پارهای بر اساس روش توابع پایه برای حل مسایل ارتعاش اجباری واستاتیک تیرها و صفحات لایه ای ارایه شده است که می توان تفاوت این روش با روش های متداول توابع پایه را در استفاده از توابع هموار در ارضاء معادلات حاکم و شرایط مرزی دانست. در روش ارایه شده در این پایاننامه از معادله تعادل به عنوان معادله حاکم بر رفتار سیستم استفاده شده است که مو...
15 صفحه اولFundamental Solution and Study of Plane Waves in Bio-Thermoelastic Medium with DPL
The fundamental solution of the system of differential equations in bio-thermoelasticity with dual phase lag (DPL) in case of steady oscillations in terms of elementary function is constructed and basic property is established. The tissue is considered as an isotropic medium and the propagation of plane harmonic waves is studied. The Christoffel equations are obtained and modified with the ther...
متن کاملWave Propagation and Fundamental Solution of Initially Stressed Thermoelastic Diffusion with Voids
The present article deals with the study of propagation of plane waves in isotropic generalized thermoelastic diffusion with voids under initial stress. It is found that, for two dimensional model of isotropic generalized thermoelastic diffusion with voids under initial stress, there exists four coupled waves namely, P wave, Mass Diffusion (MD) wave, thermal (T) wave and Volume Fraction (VF) wa...
