Does a neutron star have a mass limit? Neutron stars cannot exceed 2.2 solar masses before collapsing into black holes. How heavy can neutron stars get? Astrophysicists have long wondered how massive these stellar corpses could be without collapsing under their...
How can mass transfer to a compact object occur? 40. How can mass transfer to a compact object occur? Mass can flow from one object to another in binary systems. How does the lighthouse model explain pulsars? It is a similar...
How can we detect black holes? Astronomers spot them when another star draws near enough for some of the matter surrounding it to be snared by the black hole’s gravity, churning out x-rays in the process. Most stellar black holes, however,...
How do they discover black holes? Astronomers spot them when another star draws near enough for some of the matter surrounding it to be snared by the black hole’s gravity, churning out x-rays in the process. Most stellar black holes, however,...
Why do black holes get bigger? A common explanation for this mismatch is that black holes grow over time by gorging on gas, dust, stars and even other black holes. But because black holes often form after giant stellar explosions called...
What is the process of emission of X-ray? There are three common mechanisms for the production of X-rays: the acceleration of a charged particle, atomic transitions between discrete energy levels, and the radioactive decay of some atomic nuclei. Each mechanism leads...
How can we tell where black holes are? Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and...
What radiation Do black holes emit? Hawking radiation is the thermal radiation predicted to be spontaneously emitted by black holes. It arises from the steady conversion of quantum vacuum fluctuations into pairs of particles, one of which escaping at infinity while...
What is Hawking radiation theory? Hawking radiation describes hypothetical particles formed by a black hole’s boundary. This radiation implies black holes have temperatures that are inversely proportional to their mass. Putting it another way, the smaller a black hole is, the...
What are the steps of a star life cycle? What are the different stages of life cycle of stars? Giant Gas Cloud. Protostar. T-Tauri Phase. Main Sequence. Red Giant. The Fusion of Heavier Elements. Supernovae and Planetary Nebulae. What are the...
