Introduction to IMRIs <strong>and</strong> EMRIs<br />
Astrophysical mechanisms to produce EMRIs: The best<br />
studied one is <strong>the</strong> “Single Capture” mechanism:<br />
Scattering <strong>of</strong> a Stellar-mass<br />
Compact Object (through 2-body or<br />
multi-body encounters) to highly<br />
eccentric orbits around a MBH:<br />
M • ∼ 10 5 − 10 7 M ⊙ , 1 − e ∼ 10 −3 − 10 −6 .<br />
They expend <strong>the</strong> last year before<br />
plunging inside <strong>the</strong> eLISA b<strong>and</strong>:<br />
e ∼ 0.5 − 0.9 , no. cycles ∼ 10 5 .<br />
