innermost stable circular orbit
(ISCO)
(border of region surrounding a BH in which orbits are unstable)
The term innermost stable circular orbit (ISCO) is used
for black holes and neutron stars:
an orbit at the distance from the center of the
object (the ISCO-radius)
immediately beyond that for which general-relativity effects make such an orbit unstable.
The rotation of the host object affects this distance,
but for the simple case of no rotation:
RISCO = 6GM/c² = 3RS
(black holes,orbits)
