The impact of binary stars in the determination of the total mass of stellar system. [PDF]
, 2022 Binary stars play a very important role in the dynamics of stellar systems such as star clusters. After a detailed analysis of binary classification, formation mechanisms and both fundamental parameters and distributions, the impact of binaries in the

A Application of WD Model to EB Type Contact Binary System [PDF]
Journal of Astronomy and Space Sciences, 2000 The EB type contact binaries show large temperature difference ( T 1,000K) between two components. Thus we have modified the mode 3 of the WD program to adjust albedos, limb darkening coefficients and gravity darkening exponents for both components of ...

Load Distributing Metamaterials Via Discrete Optimization
Advanced Functional Materials, EarlyView.Mechanical metamaterials are computationally optimized to homogenize transmitted forces by minimizing the spread of reaction forces. The resulting architectures transform localized loading into broader, more uniform force distributions and experimentally demonstrate robust load spreading under quasi‐static and impact loading.

Shaping the Outflows of Binary AGB Stars
, 2015 The required conditions for stars to evolve into planetary nebulae (PNe) continue to puzzle. Since PNe are found in a wide variety of shapes, processes that could sculpt circumstellar envelopes (CSEs) are being investigated.
