Can GYRE calculate tidal oscillations of UCXBs?

Hi,

If i want to calculate tidal oscillations of ultracompact x-ray binaries (UCXBs), is that possible? Like 4U1820-30, which contains a neutron star and a he write dwarf and has a very short period. The two stars are so near, so the tidal impact will be very significant. But there seems exist two main problems:
1. The neutron star may rotate rapidly, while GYRE is suitable to low-frequency g modes of slow-to-moderately rotating systems.
2. The two stars may have matter exchange among them, i.e. accretion. This may effect tidal calculation.

So i want to ask whether GYRE or GYRE-tacs5 can calculate tidal oscillation of such system? If it can, which example i can follow as a start?

Best Regards
Chen
