The Distance to Exoplanet Systems with Imaging and Spectral

已有 729 次阅读 2023-7-27 10:06 |个人分类:思考|系统分类:科研笔记

The distance $D$ to an exoplanet system with imaging and spectral measurement can be obtained by using the orbit as a ruler. The measurement of the Distance to a typical exoplanet system with imaging and spectral measurement can be accurate to $\delta D/D\sim 0.2$, if the orbital velocity of the planet can be accurate to $\sim 3 {\ \rm km/s}$.
