The spectral slopes, infrared luminosities and mass loss rates of central stars, as well as the mass loss times from infrared or radio radiation are calculated.

计算了光谱斜率和红外光度，同时从红外及射电幅射得出了中心星质量损失率及质量损失历经时间。

The team has now used these data to compile the largest catalogue of the central concentration of stars in the Milky Way ever created.

ENGADGET: 9-gigapixel image of the Milky Way reminds us just how small we truly are

Observing the motions of the stars orbiting the central object allows scientists to estimate its mass.
