Storyboard Text

  • Main Sequence
  • The bigger I get, the less I will live. *Sad face*
  • Brown Dwarf
  • I always wanted to be cool but not like this!
  • Red Dwarf
  • I have less than half the mass of the Sun!
  • I'm in the lower right corner of the H-R diagram.
  • This is it for me. Scientists have no evidence that I will ever evolve any further. *Sigh*
  • I'm Manny, the Main Sequence star. Right now, I am in the prime of my life along with 90% of other stars. I'm healthy and have a balanced mix of weight and fusion in my core! I love to fuse hydrogen atoms to make helium atoms in my core. I wonder how big I'll grow to be, stars like me can range from a tenth of the mass of Earth's sun to 200 times as massive. I feel like I'm losing mass in my core. If it gets too low, I'll turn into a brown dwarf.
  • A Red Dwarf's Fate
  • Hey guys, its Manny here. Now I am a Brown Dwarf star. I have too little mass to fuse hydrogen in my core. Soon, if I get cool enough I will develop my own complex atmosphere with molecules like methane. In this way, I share the traits of a star and planet. Cool! Literally. Sadly, I don't have a central energy source so I will cool down forever. Although, I will be easy to find with infrared surveys because I become redder as I cool. *Blushes*
  • Electron Degeneracy Pressure
  • It's Manny again. This time I'm a Red Dwarf! I am now slighter above Brown Dwarfs on the Hertzpring Russel (HR) Diagram, a astronomical tool used to classify stars based on color, luminosity, spectral type, temperature, and evolutionary stage. As I have become a cool star, I have learned to take things slow and enjoy life. I can live for billions of years as I very slowly fuse atoms in my core. My long life is due to my lean weight and relaxed lifestyle. 
  • Billions of Years Later...?
  • A Black Dwarf occurs when a White Dwarf has stopped producing light or heat. The estimated time for this to occur would be longer than the present age of the universe. Maybe, I will be the first!
  • As I am not going to evolve again, I figure I should think about what will happen when I die. Albeit, no known Red Dwarf stars have ever died. I imagine that eventually hydrogen will run out and my nuclear fusion will cease. At this point, my internal pressure will drop and contract, there is nothing preventing gravity from collapsing me.
  • The Pauli Exclusion principle states that fermions, a particle with a half-integer spin (for example an electron), cannot occupy the same quantum mechanical state. In short, there is a limit to how much gravity can squeeze the star together. At the end, I Manny, will be a White Dwarf composed of almost 100% Helium. Although in theory...
  • I am very dense. My mass is comparable to the sun, while my volume is like that of the Earth.
  • I am now Manny the White Dwarf!
  • Manny the White Dwarf here. In theory, after hundreds of billions more years I might cool down to temperatures like that on Earth. Say, 80 degrees Fahrenheit. At this point, I will be essentially invisible. Some may start calling me a Black Dwarf. I won't stop cooling until I reach a few degrees above absolute zero!
