标题： Have mirror planets been observed?

摘要： 在过去几年中，已经发现了附近恒星周围一些近距离轨道（$\sim 0.05$AU）的大质量行星（$M \sim M_{Jupiter}$）。 它们的存在是通过恒星光谱中的微小多普勒频移推断出来的。 我们建议这些行星可能是由镜像物质构成的。 我们还指出，像我们的太阳这样的恒星也可能含有类似量的镜像物质，但由于某种微弱力的作用，如光子-镜像光子动能混合或其他因素，尚未被探测到。 显示英文摘要

摘要： Over the last few years, several close orbiting ($\sim 0.05$ AU) large mass planets ($M \sim M_{Jupiter}$) of nearby stars have been discovered. Their existence has been inferred from tiny doppler shifts in the light from the star. We suggest that these planets may be made of mirror matter. We also point out that some stars such as our sun may also have a similar amount of mirror matter, which has escaped detection due to the effects of a tiny force such as photon - mirror photon kinetic mixing or something else.
