Low Mass X-ray Binary
The unusual properties of Low Mass X-ray Binaries may be the recognition of a Black Hole/White Hole partnership with a physical connection between them as a time bridge (in purple). This gravitational connection assists the Black Hole in pulling it's own White Hole partner into a binary - which, if true, would predict their unusual characteristics.

The number of low mass objects in the Galaxy available for BHs to capture randomly is very small but the number of LMXB is comparatively large because BHs have a ready made partner as part of their formation. The partners are forged in a special way giving them a causal link in evolution showing an association in mass at a ratio of about 1to20 - a general correlation, as that ratio may change over time, but too narrow to be random.
This gravitational connection creates the unusual orbit of the secondary being attracted through the bridge as well as generally. The Time Bridge forms an extra force pulling on the low mass partner before transit, then slinging past in an elliptical orbit. The Bridge forms a 'drag' in the outward journey slowing the partner and broadening the orbit.
The low mass partner is often a Be star, with unbound mass, which passes to the BH in accretion turned to antimatter and passed back through the Time Bridge (antimatter is opposite gravitational in this scenario) to the secondary in a matter/antimatter rotation. Activity at the secondary only occurs once matter accretion commences to the BH. It takes time for matter to spiral into the BH so the partner may past the transit before becoming active. Then, as the BH flares in variations in accretion so the low mass partner flares (at the speed of light) showing a physical connection as antimatter passes through the unseen Bridge. That speed has a time travel connection as matter at the speed of light moves in time.
These binaries are known to produce antimatter in vast clouds. That is only produced at the inner accretion zone and must somehow travel from there, escaping the BH, to become unbound.

This cloud matches the distribution of a population of binary star systems that contain black holes or neutron stars, strongly suggesting that these binaries are churning out at least half the antimatter or perhaps all of it.
Antimatter only generated at the inner accretion zone. Has to escape BH somehow and out through the 'poles'. Antimatter is lost and repelled by BH binary, being graviationally negative, to become unbound 'clouds' unless converted back to matter.
The structure shown (top) predicts an interaction of the antimatter Time Bridge with the matter in the accretion disc that may demonstrate the unseen gravitational bridge. As the BH and WH come together the accretion rate increases and matter in the disc could interact with antimatter in the filament forming a powerful but intermittent 'Hot Spot' on the outer accretion zone.
This association predicts how the secondary can orbit close to the BH without being destroyed. As the two get closer the matter rotation increases as more is striped from the secondary and more is passed back to it. This stream of material, though the bridge, forms an outward force to resist coalescing.
The unseen connection and the rotation of matter help to understand how this sort of binary generate Standard Luminosity as this scenario can attribute much of the matter loss to the BH. The 'wind' antimatter creates as it passes the BH and ejects the 'poles' is powerful enough to pull the material off the 'surface'. Jetting (that which is not collected by the time bridge and non gravitational) contains emissions from the BH itself at around 30%. This loss is replaced in powerful accretion as the BH may become bigger over time. In minimal accretion losses may outweigh gains and BH shrinks until it's gravity can no longer keep it stable. That point is the same every time leading to the same size explosion of a standard type.
