2018-10-03 Server Crash, Black Holes, Neutron Stars

[cami]

Amazingly beautiful (and terrifying)! I'm willing to take the blame of asking for this repeatedly, although I certainly wasn't the only one.

Speaking of beauty: stellar remnants, particularly white dwarves but also neutron stars, illuminate the most beautiful planetary nebulae around them, formed by their "death".

Edit: looks pretty good on my personal check list now:

• Y Main Sequence
  
• Y Giants / Subdwarves
  
• ~ Remnants (mostly)
  • Y Stellar black holes
    
  • Y Neutron stars
    
  • ? White dwarves
    
  • ~ Planetary nebulae: rather random, but should be around most if not all remnants
    
  • - brown dwarves (failed stars)
    
• ~ Transitions (mostly)
  • Y Wolf rayet stars (mostly look like a main sequance star with a planetary nebula)
    
  • - Pulsing Variable (e.g. Cepheids)
    
  • - Interacting (probably not worth it - too many types and little is known except for specific types like Ia supernovae)
