New Estimates of the Spin and Accretion Rate of the Black Hole M87*

open access: yesThe Astrophysical Journal Letters
In this Letter, we use the imaging results of M87* from the Event Horizon Telescope (EHT) to calculate the rotational velocity of the inner edge of the accretion disk and find a value of ∼0.14 c .
