It has long been suggested that X-ray transients are produced at periastron of stellar-compact object binaries with eccentric orbits. Recoil of matter evaporated from the star by X-rays from matter transferred at periastron increases the orbital semi-major axis and eccentricity. After periastrons the object would be a transient X-ray source, a Galactic analogue of a tidal disruption event (TDE), but recurrent with a gradually increasing period rather than catastrophic.
