This paper presents the first calculation of the gravitational self-force on a small compact object on an eccentric equatorial orbit around a Kerr black hole to first order in the mass-ratio. That is the pointwise correction to the object’s equations of motion (both conservative and dissipative) due to its own gravitational field, which is treated as a linear perturbation to the background Kerr...

PURPOSE To evaluate the incidence, clinical features, and outcomes of macular hole formation after pars plana vitrectomy with internal limiting membrane peeling for the management of epiretinal membrane. METHODS Retrospective consecutive chart review of 423 cases. RESULTS Eleven subjects developed postoperative macular holes (incidence 2.6%; 95% confidence interval, 1.5-4.6%). Two of the 11...

We study the motion of gas clouds in vicinity boson stars, performing simulations with black hole accretion code. compare particle along geodesics and analyze tidal effects on clouds, which leads to disruption clouds. First we consider small dense associated three different types bound orbits close star mechanisms debris formation for these. infer from that lifetimes these nearby are longer ini...

We review some observational aspects and theoretical models for the formation of the young massive stars in the central parsec of our Galaxy. It is concluded that an in-situ star formation model provides the best description of the data. One possible guess for the initial gas configuration is one circular and another eccentric gas discs, not necessarily coeval during their short lifetimes. The ...
