Protostar
Wikipedia lists it as a main sequence star. That means that it still has significant amounts of hydrogen. Main sequence stars also typically have a smaller amount of helium (remember, the hydrogen gradually converts to helium), and even smaller amounts of the so-called "metals" (i.e., all other elements).

The process is nuclear fusion of hydrogen. All stars at their main sequence converts hydrogen to helium giving large energy by during hydrogen atoms into helium nucliiFusion of hydrogen.
In the HR-diagram, a diagram of color vs. luminosity, most stars are concentrated close to one curve, called the "main sequence". It turns out that stars on the main sequence are the stars that mainly get their energy by converting hydrogen into helium.
No. Main sequence stars are simply stars that are fusing hydrogen into helium and have a specific relationship between color and luminosity. They range from red dwarfs to large O-type main sequence stars.
The main sequence phase means that, if you plot an H-R (Hertzsprung-Russel) diagram, it is in the so-called "main sequence", the area in the graph where you find the majority of stars. Those are the stars that currently fuse hydrogen into helium.
hydrostatic
Like a camera has a case, the eye is surrounded by tissues and are filled with fluid called "humours" to keep it from collapsing.
It's called a breaking wave or breaker.
This is called a breaking wave also known as a breaker.
Such a sequence is called a quint.
