1. Correct, I simply listed the top 10 brightest stars in my cheat sheet as a good reference. One would have to find the apparent magnitudes of the other stars, though.IHateClouds wrote: ↑January 19th, 2020, 6:04 pm1. out of curiousity, how would you go about this other than checking the apparent magnitude of all the stars? like do you keep a list of the stars in order of apparent and aboslute mag on your cheat sheet? altho even that seems slow anyway...Locoholic wrote: ↑January 19th, 2020, 2:36 pm
1. Rank these stars from brightest to dimmest when viewed in the night sky: Arcturus, Sirius, Vega, Betelgeuse, Antares, Rigel, Procyon, Capella.
2. What is the limit for stars to be considered to be First Magnitude?
3. After which theoretical mass does a star begin to use the CNO cycle more than the proton-proton chain as a method of nucleosynthesis?
sirius: -1.46
arcturus: -.05
capella: .08
rigel: .13
vega: .026
procyon: .34
betelguese: .5
antares: 1.1
2. less than an apparent magnitude of 1->"first"
3. over 1mass of sun/M
2. It’s actually +1.5. 3. 1.3 Solar Masses. Your turn!
