How can I write this reference in BibteX?

Question

This reference contains a formula and when I write it as follows

@article{romeo2011effective,
title={The effective stability parameter for two-component galactic discs: 
is $Q^{- 1}\sim Q^{- 1}_{stars}+ Q^{- 1}_{gas}?$},
author={Romeo, Alessandro B and Wiegert, Joachim},
journal={Monthly Notices of the Royal Astronomical Society},
volume={416},
number={2},
pages={1191--1196},
year={2011},
publisher={The Royal Astronomical Society}
}

there are some errors (missing $ or missing a {). Note that I'm using a Persian thesis template (it can be found here).

This title comes from google schoolar.

Note that, using {$Q^{-1}\sim Q^{-1}_{\text{stars}}+Q^{-1}_{\text{gas}}$}?, the numbers appear in the formula, are in Persian. Thanx

What have you tried so far (single $ not double -- it's inline maths, and anyway $$ is a bad idea)? — Chris H, Jul 17 '18 at 15:26
OK, now what errors? What did you try to type it as? — Chris H, Jul 17 '18 at 15:30
Please help us (and also you) and add a minimal working example with bibliography (MWEB), that illustrates your problem. Your code isn't compilable (at the momenT). — Bobyandbob, Jul 17 '18 at 15:48
@Bobyandbob : Sorry for ambiguities. If it helps, I bring the link of thesis sample. — Perfect Fluid, Jul 17 '18 at 16:08
Change $Q^{- 1}\sim Q^{- 1}_{stars}+ Q^{- 1}_{gas}?$ to {$Q^{-1}\sim Q^{-1}_{stars}+Q^{-1}_{gas}$}? should be fine. Also, if you have loaded amsmath, consider {$Q^{-1}\sim Q^{-1}_{\text{stars}}+Q^{-1}_{\text{gas}}$}?. — Ruixi Zhang, Jul 17 '18 at 16:33
@RuixiZhang: Thank U so much. It seems to be ok now. However, the numbers in this formula are in Persian :( — Perfect Fluid, Jul 17 '18 at 16:50
