Answer	—	A: How much does my secondary star heat the planet orbiting my primary star? Actually, since the mass luminosity relationship is to the 4th power, if star B had double the mass of star A it would have 16 times the luminosity. Now, 16/400 = 0.04, so you would get 4 percent of the heating of the sun. This actually could cause appreciable warming... note that it is postulated ... (more)	—	almost 9 years ago
Answer	—	A: What if the Planck constant was exactly zero? Everything might be pitch black. Because there would be an infinite number of orbitals in each molecule (instead of discretized solutions to the Schrodinger equation (i.e. Hamiltonian) you would have infinitely many solutions to the spectra at infinitesimally-different energy levels) any photon coul...

Answer	—	A: How can I safely brighten my secondary star? Roughly, to get the brightness from that of the full moon to an overcast midday, you need to increase the luminosity about 4000 times (Wikipedia: Daylight). Thus you would have to bring in the secondary star from 100 AU to 10 AU to get it 100 times brighter (i.e. from 40 times the brightness of the ... (more)	—	about 9 years ago
