Types of Stars Crossword Puzzle

QUESTIONS LIST:

• neutron stars : has a mass of only between 1.35 and about 2.1 times that of our sun, it is 60,000 times smaller than the sun
• brown dwarfs : "failed stars", which form from clouds of interstellar gas, as other stars do, but never reach sufficient mass, density and internal heat to start the nuclear fusion process.
• binary stars : two stars in close proximity which orbit around their common center of mass.
• black dwarfs : hypothetical stellar remnants created when a white dwarf becomes cool and dark after about ten billion years of life
• red dwarfs : small and relatively cool stars, bigger than brown dwarfs, but less than 40 - 50% of the mass of our sun.
• blue giants : bright, giant stars, between 10 and 100 times the size of the sun
• red giants : luminous giant stars of low or intermediate mass (usually between 0.5 and 10 solar masses) in a late phase of stellar evolution
• variable stars : stars that grow and shrink in size periodically and appear to pulsate.
• white stars : bright, main-sequence stars with masses from 1.4 to 2.1 times the mass of the sun
• white dwarfs : is typically only the size of the earth, but 200,000 times more dense.
• yellow dwarfs : main-sequence stars like our own sun, typically about 80 - 100% of the size of the sun
