contact binary 中文意思是什麼

contact binary 解釋
密接雙星
  • contact : n 1 接觸；聯系；交涉。2 〈美國〉（有勢力的）熟人；門路。3 【數學】相切；【電學】接觸；觸頭；觸點...
  • binary : adj. 二，雙，復；【化學】二元的；【數學】二進制的。n. 二，雙，復；雙體，復體；【天文學】雙[聯]星【數學】二進制。
  1. We calculate a model with angular momentum loss caused by gravitational radiation, and find that the binary undergo cyclic evolution as well. however, the period of the cycle becomes shorter, and the ratio of the time spent in the semi - detached phase to the time spent in the contact phase in a cycle becomes smaller

    我們計算了由引力波輻射引起雙星系統的角動量損失的演化模型，發現雙星系統還是經歷循環演化，不過循環的周期變短，且雙星系統的每一個循環處在半接狀態的時間與處在相接狀態的時間之比變小。
  2. Contact binary : in these binary stars, components are too close together that they have material exchange. the mutual gravity may also deform the stars and glue them together

    ：這種雙星系統，子星間的距離十分接近，強大的引力不單只把恆星拉扯至變形，更造成子星間出現物質交換，把兩星連接起來。
  3. Near - contact binary

    接近相接雙星
  4. Combined with the observational properties, we have constructed a theoretical model of a contact binary with a total mass of 1. 8 mo. our initial model is a detached binary in which the primary is very close to its roche lobe

    並且由周期變化時標得到磁滯效應可能是引起wuma型相接雙星的角動量損失的主要物理機制。結合wuma型相接雙星的觀測特性，我們建立了一個總質量為1 . 8m 。
  5. It evolves into a semi - detached binary after about 2. 7 myr, and its secondary fills its roche robe after 34. 5 myr, and then evolves into a contact binary. contact phase is characterized by energy transfer between the components through a common envelope

    初始模型是一個主星十分接近其內臨界等位面的分離雙星，大約演化2 . 7 10 ~ 6年成為半接雙星，經過3 . 45 10 ~ 7年次星開始充滿洛希瓣，而演化成相接雙星。
