Some stars are more or less luminous than the Sun, depending on the temperature of the star, the size of the star and how far away it is. A star that is white-hot will be more luminous than the Sun, which is only a bright orange, because of the exceedingly hot temperature. 2. The length of the Sunspot Cycle is 11 years. The magnetic polarities reverse every time a new Sunspot Cycle begins. 3. The significance of 1.4 solar masses refers to the Chandrashankar limit. At 1.4 solar masses, a star turns into a neutron star. At 3 solar masses, the star itself cannot hold its own gravity any more and implodes into a point of singularity, known as a black hole. 4. The difference between a spectroscopic binary and a visual binary is that a spectroscopic binary occurs when you see a binary from Earth as one star, but the spectral lines show back and forth Doppler shifts as the two stars orbit each other.
