# 6 mark question about stars (physics) - how many marks is my response?

Announcements
#1
My response roughly.. don't judge me since I'm a dumb student:

A protonstar (I know it's protostar, mistake) is formed by dust reacting with gas under gravity. The star, a similar size to the sun, becomes a red giant and collapses under it's own gravity to form a white dwarf. The white dwarf then cools and loses it's brightness to become a black dwarf.

It doesn't seem like I've wrote enough for 6 marks.. maybe I missed part of the question or just forgot what I wrote..

Is that all you wrote for the 6 marker or is there more?

You will probably get 3 marks, because you have described the cycle of star that has similar size to the Sun.

You develop, you should've talked about the cycle of a star bigger than a Sun. This is that it goes and becomes a supernova, which is an explosion and this leads onto a black hole or neutron star.

Something like that anyway. But I am sure you will get 3 marks for that question so don't worry.

No, the question only said to describe stars similar to our sun.
But I still don't think the OP got full marks.
You forgot to mention main sequence and the fusion of hydrogen atoms.

Yeah, you have to mention that first and then talk about the cycle of the stars. I'm sure the question said describe the life cycle of stars. It did not specifically say whether to write about stars similar to the Sun or bigger than the Sun. So you were expected to write about both cycles.

What? O. O for the aqa one I'm pretty sure it said "such as our sun" somewhere.

The question did say "such as the sun" which I inferred meant a similar size to the sun.
