True or false
- Flux is not related to the distance from the source.
True or false
- A G star is hotter than an M star.
True or false
- Parallax is a good method to find the distance to a star say 1300 LY away.
True or false
- The power output of a star at the source is
Flux, Luminosity, Apparent brightness
- Flux seen at a distance from a source depends on
its luminosity, the area over which the observer receives the light, both of the above
- The distance at which a star’s parallax is one arc second is called
a parsec, a light year, stellax
- The light flowing through the surface of a star is related to
it surface temperature, its mass, its age, all of the above
- The continuous spectrum peak wavelength gives us the surface temperature by
Boltzman’s Law, Wien’s Law, The Law of Temperature, No answer text provided.
- The sun’s temperature-color (spectral) classification
O,a,g,m
- An optical double is not a real binary.
True or false
- Mass is notthe determining factor in stellar evolution.
