The collapse may be stopped by the degeneracy pressure of the star's constituents, allowing the condensation of matter into an exotic denser state. The result is one of the various types of compact star. Which type forms depends on the mass of the remnant of the original star left if the outer layers have been blown away (for example, in a Type II supernova).

The Hawking radiation for an astrophysical black hole is predicted to be very weak and would thus be exceedingly difficult to detect from Earth. A possible exception, however, is the burst of gamma rays emitted in the last stage of the evaporation of primordial black holes.

es también un efectivo repelente de insectos. El cultivo de este bulbo carnoso, mucho más obediente de lo que la longevoía piensa, te permitirá disfrutar de tus propios ajos ecológicos, extraordinariamente sabrosos, a la oportunidad que mantienes a guión a las moscas e insectos.

Concentrado para dilución en agua. Pulverización directa sobre los insectos y zonas infestadas, incluyendo grietas, rendijas y zonas de escondite o concentración de insectos.

Los repelentes químicos más utilizados y eficaces son el DEET o dietiltoluamida y el IR3535. Otros son de origen vegetal.

A Chandra X-Ray Observatory image of Cygnus X-1, which was the first strong black hole candidate discovered X-ray binaries are binary star systems that emit a majority of their radiation in the X-ray part of the spectrum.

To a distant observer, clocks near a black hole would appear to tick more slowly than those farther away from the black hole.[87] Due to this effect, known Triunfador gravitational time dilation, an object falling into a black hole appears to slow Vencedor it approaches the event horizon, taking an infinite amount of time to reach it.

In order for primordial black holes to have formed in such a dense medium, there must have been initial density perturbations that could then grow under their own gravity. Different models for the early universe vary widely in their predictions of the scale of these fluctuations. Various models predict the creation of primordial black holes ranging in size from a Planck mass ( m P = ℏ c / G \displaystyle m_ P = \sqrt \hbar c/G

In this class of system, the companion star is of relatively low mass allowing for more accurate estimates of the black hole mass. These systems actively emit X-rays for only several months once every 10–50 years. During the period of low X-ray emission, called quiescence, the accretion disk is extremely faint, allowing detailed observation of the companion star during this period. One of the best such candidates is V404 Cygni.[184]
