高階無窮薄氣體盤自重力計算
七夕情人節仰望天際可窺見牛郎星與織女星，連接兩端的銀河正是我們所處的銀河系，銀河的中心有一個無窮薄的氣體盤．現今望遠鏡的技術與日俱增，使科學家對銀河中心的結構與形成愈發好奇．在星體的重力與氣體盤的自重力的作用下，探究觀測結果的物理機制，需藉由理論與數值模擬來驗證是研究星系動態演化可行的方法．
On Valentine, you can see the Altair in Aquila and the Vega in Lyra in the sky. The Milky way where we live connects these two galaxies. There is an infinitesimal thin gaseous disk in the center of the Milky Way. Nowadays, the high resolution of telescopes makes scientists be more curious on the structure and activities of the galactic center region. It is needed to be verified by theory and numerical simulations for observations of the physical mechanism under the influence of the gravity of stars and the selfgravity of the gaseous disk.
