Brown dwarf Star

Maybe some of you don't know there is a star that almost undetectable.The star is brown,small and "Failed Star''.The star is known as the Brown Dwarf.The similarities between the star and brown dwarf is their own formation,gravitational collapse from dust and gas.But,mostly Brown Dwarfs are drop out of the stellar university and spend of its' life as THE FAILED STAR.

Let me show you how it's formed:

1)Gathering gas and dust cloud

-The interstellar gas and dust will gather and denser,The gas that from Hydrogen and Helium,which form a little amount of deuterium[heavy Hydrogen] and some lithium.The centre will get more denser than it's own surroundings.It will make a seed that the star will grows up.

2)The young protostar

-Luckily, the extra gravitational pull from the seed sucked/drawn the cloud's materials into the centre until the young protostar is born.

3)The gaining fusion 

-Protostar somehow will gains mass and contracts under it's own weight.As it denser,the core will heats up until it is hot enough to fuse the deuterium.Energy created by the fusion from deuterium that will heats up the protostar to several million degrees and stop shrinking.

4)Dreams that won't come true

-The young protostar will daydreaming but here it ends.It will runs out of the fuel of deuterium and hasn't gained enough mass to keep the fusion process keep going[It would takes more energy to fuse the Hydrogen].

5)Cool it off!

-After no new energy was created in the core,it starts to cool down and shrinking.

6)The Identical

-Eventually,BROWN DWARF will be almost identical/twins to gas giant planet.

7)Invisible and undetectable

-In somehow,it cools completely and almost undetectable/invisible.
