Do "isolated" planetary mass objects orbit mirror stars?

Abstract

We propose that the ``isolated'' planetary mass objects observed by Zapatero Osorio et al in the Orionis cluster might actually be in orbit around invisible stellar mass companions such as mirror stars. Mirror matter is expected to exist if parity is an unbroken symmetry of nature. Future observations can test this idea by looking for a periodic Doppler shift in the radiation emitted by the planets. The fact that the observations show an inverse dependence between the abundance of the these objects and their mass may argue in favour of the mirror matter hypothesis.
