Stars that burn cooler and dimmer use less fuel, and so will last longer before they go out. smaller stars are generally more stable than larger ones, and so usually last longer because they contract into dwarf stars instead of going supernova. going with those assumptions, the longest-burning star would be a red dwarf star.

The stars that have the longest lifetimes are the smaller, cooler stars - red dwarfs. They are just about massive enough to sustain nuclear fusion of hydrogen fuel, but consume fuel at a very low rate. They could last for hundreds of billions of years before they exhaust their fuel.
The cells that last the longest are nerve cells, they last a lifetime
White dwarf stars are theorized to be the final evolutionary state of all stars that did not become neutron stars. This stage is the longest in a stars life outside of black dwarfs which are white dwarfs that have cooled dramatically.
Red dwarves.
I think Bubblelicious last the longest.

The Longest Day
the one that lasts the longest!
The stars that are spaced less than your latitude from the celestial pole never set.
