Influence of the Choice of Core-Envelope Transition Point on the Binary Merger of Two Main-sequence Components     

Xue-Fei Chen  Zhan-Wen HanNational Astronomical Observatories  Yunnan Observatory  Chinese Academy of Sciences. Kunming  Graduate School of the Chinese Academy of Sciences  Beijing 《中国天文和天体物理学报》2005,5(1):65-76

We have studied the influence of different choices of core-envelope transition point on the final merger of contact binaries with two main-sequence components. A binary of 1.00 + 0.90M⊙ with an initial orbital period of 0.35d is examined. The mass fraction of the primary mixed with the matter of the secondary, qmix, determined by the chosen core-envelope transition point, ranges from 0.04 to 1.00 in our analysis. If as qmix< 0.8, none of the  相似文献   

Th-and U-bearing minerals in the SE Mediterranean margin of Spain     

JesusMartinez-Frias RosarioLunar RaulBenito 《《幕》》2004,27(1):33-38

This paper presents the first specific study of the Th-and U-bearing minerals, which were recently found in the SE Mediterranean margin of Spain (El Hoyazo area,Almeria province). These minerals are REE phosphates (mainly monazite) which occur as amoeboidal-to-elongate inclusions,from around 10 120μm to 120μm, hosted in single garnet crystals from dacite lavas and metamorphic rocks from the El Hoyazo Volcanic Complex. Th and U contents are higher than 1 wt%, with 3.04 to 5.62wt% for Th02, and 0.7 to 1.75 wt% for UO2. Both elements are also found in xenotime (ThO2:0.24,UO2:0.27wt%). Given that the erosion of the volcanic source rocks has generated a “placer-type” deposit of monazite sands and that garnets (main carriers of monazite) are being commercialised, an environmental monitoring and management plan should be urgently executed in the area.  相似文献

富碳拱星IRC＋10216和CIT6的CO J=1—0转动谱的观测     

裴春传  陈亚峰 《紫金山天文台台刊》1997,16(4):226-231

使用中国科学院紫金山天文台青海站13.7米射电望远镜于1996年12月至1997年1月对富碳拱星IRC 10216和CIT6的CO J=1-0跃迁(115GHz)进行了观测。在观测谱线的基础上得到了IRC 10216的视向速度和膨胀速度分别为一26.1km s~(-1)和14.8km s~(-1),CIT6的视向速度和膨胀速度分别为0.6km s~(-1)和13.8kms~(-1)。并对望远镜的射束及指向精度进行了研究。  相似文献
