Luminosity is proportional to temperature (T^4). Stars are formed in giant clouds of dust and gas, and progress through their normal life as balls of gas heated by thermonuclear reactions in their cores. Luminosity is proportional to mass. The reason is that as light travels towards you, it is spreading out and covering a larger area. The course draws on the Emmy-award winning film, Journey of the Universe, and the book from Yale University Press. Stefan-Boltzmann Law and is stated mathematically as: Use the magnitude system (M, m) to compare the brightness of objects. First, the universe has been evolving with time.

Depending on their mass, they reach the end of their evolution as a white dwarf, neutron star or black hole. stars transfer energy from their core to their surface- how is this dependent on the primary reactions in the core? Think you’ve got a decent knowledge of the universe? Second, the universe has been expanding with time. The apparent magnitude of a star has an equivalent flux, or apparent brightness. How does density, temp, and pressure change from the core of the sun outward through the atmosphere. Since the Balmer series lines require electrons to already be in level 2, if there are no hydrogen electrons in level 2 in the gas, there will not be any Balmer series hydrogen lines created by that gas. - Predict the wavelength of any given transition.

This week we will be exploring some of the means we have at our disposal to find out many things about the stars. Thus, the stars with the strongest hydrogen lines must be in the middle of the temperature sequence, since their atmospheres are hot enough that hydrogen will have its electrons in level 2, but not so hot that hydrogen becomes ionized.
