In the paper Tachyon motion in a black hole gravitational field by V. M. Lipunov he writes:

(…) Circular orbits for tachyons begin at the distance of $ 3/2~r_g $, i.e., at the distance of the innermost unstable orbit of ordinary particles. Note that the innermost unstable circular orbit for a tachyon is located at the gravitational radius and corresponds to a tachyon that is transcendent at infinity and has angular momentum $M=m~c~r_g $. (...)

Note that the innermost unstable circular orbit for a tachyon is located at the gravitational radius and corresponds to a tachyon that is transcendent at infinity and has angular momentum $M=m~c~r_g $.

I cannot find such notion on internet, to find is only innermost stable circular orbit (ISCO) or marginally stable circular orbit (MSCO).

I cannot find the meaning of IUCO. Is that possibly asuch notion on internet, to find is only innermost stable circular orbit (ISCO) or marginally stable circular orbit (MSCO)?.
