Answer #1

Star are created though the nuclear fusions process where huge amount mass gatherd and due to gravity create emense pressure, elements are start squeeze under the pressure . As As pressure increase is the temperature also started Rising and its rich a certain point Where are the nuclear fission take place between the lighter element (hydrogen to Helium and periodically upward elements it's stop iron nickel) and release huge amount of energy

But this process is happened only at certain range that is called Chandrasekhar limit from 1.4 mass of sun to 50-60 mass of sun.

For low mass star this is not possible as its temperature not high enough for the nuclear fusion reaction

A binary pulsar is a system of two neutron stars of equal mass (each about 1.4 times the mass of the sun and a radius of 10km). A particular binary pulsar has two neutron stars orbiting around their center of mass, and separated by a (center to center) distance of d= 7.0*10^8m. Assume the orbit is circular. a) Calculate the orbital speed of the stars in meters/second. b) Calculate the magnitude of the centripetal acceleration of one of the stars...

A binary star system consists of two equal mass stars that revolve in circular orbits about their center of mass. The period of the motion, T = 26.4 days, and the orbital speed v = 220 km/s of the stars can be measured from telescopic observations. What is the mass (kg) of each star?

Large stars can explode as they finish burning their nuclear fuel, causing a supernova. The explosion blows away the outer layers of the star. According to Newton’s third law, the forces that push the outer layers away have reaction forces that are inwardly directed on the core of the star. These forces compress the core and can cause the core to undergo a gravitational collapse. The gravitational forces keep pulling all the matter together tighter and tighter, crushing atoms out...
