Selected Research精選研究

Binary systems are dynamic laboratories. My work follows how their disks warp, precess, and feed the stars at their center.雙星系統是研究動力學的天然實驗室。我的工作追蹤其盤面如何翹曲、進動,以及如何向中心恆星供給物質。

Pulsed Accretion onto Eccentric Binaries偏心雙星的脈衝吸積

How does strong disk–binary misalignment alter orbital-timescale accretion variability?強烈的盤—雙星傾斜如何改變軌道時標上的吸積變率?

Portrait of Ruiqi Yang outdoors

I am a PhD student at the School of Physics and Astronomy (opens in a new tab), Sun Yat-sen University (opens in a new tab). My research focuses on the dynamical evolution of circumbinary disks.

Using the SPH code PHANTOM (opens in a new tab) and grid-based ATHENA++ (opens in a new tab), I study binary–disk misalignment, accretion variability, and planet–disk interactions. I am also learning RADMC-3D (opens in a new tab) and MCFOST (opens in a new tab) to connect simulations with observations and develop testable predictions.

我是中山大學物理與天文學院(在新分頁開啟)的博士生,研究聚焦於環雙星盤的動力演化。

我使用 SPH 程式 PHANTOM(在新分頁開啟) 與網格流體動力學程式 ATHENA++(在新分頁開啟),研究雙星—盤面傾斜、吸積變率,以及環雙星盤中的行星—盤面交互作用。目前我也在學習 RADMC-3D(在新分頁開啟)MCFOST(在新分頁開啟),希望將數值模擬與觀測連結,進一步提出可檢驗的觀測預測。
