Distinguishing black holes from naked singularities through…

We show that, in principle, a slowly evolving gravitationally collapsing perfect fluid cloud can asymptotically settle to a static spherically symmetric equilibrium configuration with a naked singularity at the center. We consider one such asymptotic final configuration with a finite outer radius, and construct a toy model in which it is matched to a Schwarzschild exterior geometry. We examine the properties of circular orbits in this model. We then investigate the observational signatures of a thermal accretion disc in this spacetime, comparing them with the signatures expected for a disc around a black hole of the same mass. Several notable differences emerge. A disc around the naked singularity is much more luminous than one around an equivalent black hole. Also, the disc around the naked singularity has a spectrum with a high frequency power law segment that carries a major fraction of the total luminosity. Thus, at least some naked singularities can, in principle, be distinguished observationally from the black holes of the same mass. We discuss the possible implications of these results.

Hi! I’m David, in NJ…been practicing nudism moderately for 20 years. I want to share with you some information, about a great nudist organization which I experienced for the first time over St. Patrick’s Day weekend.

They’re known as West Penn Naturist of Pittsburgh. Do search them out here on FB!

From September thru April, they host a series of indoor nude swim parties…each uniquely themed, held at the Olympic Swim And Health Club in East Pittsburgh.

They also host special meetups at White Thorn Lodge, a nudist campground and resort in Darlington, PA, north of Pittsburgh.

Do pass the information on! Great organization, if anyone’s visiting Pittsburgh on a weekend trip. Not to be missed! 🙂
