ASTA02H3 Lecture Notes - Gravitational Redshift, Horizontal Branch, White Dwarf
Document Summary
Fuses hydrogen to make helium to sustain it. Determines how long the star will last. Note that any equality for the purpose of this course can be viewed as a proportionality. Note that and are constants of proportionality. Cross out and it becomes replace with. Equations that will not be provided on the exam. Distance of the sun to the center of the galaxy is 800kpc. Turning of its gravitational energy to heat. Red giant inert core, hydrogen shell burning. As the red giant expands, the core is still collapsing two sources of energy. The more luminous a blackbody is, the lower its temperature will be. As a rule, are more luminous than the sun. Fusion of helium into carbon and oxygen in core. Stars move on hr diagram right and up, then back to the left. Loss of mass due to solar wind infrared stars. Has a lot of dust re-radiates star.
