yeah take a look at intro to modern astrophysics by carroll and ostile

first they break past the electron degeneracy pressure then the neutron degeneracy pressure. the gravity keeps collapsing so the space curves to a "point" with a deep potential

all stars depend on Tunneling to start Nuclear fusion. I have not come across any star in my course where we talked about breaking the coulomb barrier

you should check out http://tutorial.math.lamar.edu/ <--- Its Pauls notes on Calculus I II III it got examples so it should be good.

its because of electron degeneracy pressure if they surpass this radius means increase in mass and White Dwarf would explode. so this means that most Earth size objects are supported by electron degeneracy pressure correct? P.s thanks for the reply :)

sorry, its the Hertzsprung-Russell Diagram(HR-diagram) they are referring to

why do the smallest luminous objects lie along a line on the HR diagram corresponding to radius of 1 Earth radius? I'm kinda lost on this question its from past exam.. I think it has to do with degeneracy pressure but that does not sound right to me... could someone help me out?

in terms of concept you answered my question thanks calculation I can deal with :wink:

thanks for the reply so if we were to contract a star from atomic hydrogen, would we need more mass or density in terms of particle? because atomic hydrogen is less massive than molecular hydrogen?

Atomic Hydrogen gas cloud to Star! what would be different about stars and their formation if interstellar medium only has atomic gas and nothing else? how would it affect stellar interior and energy production? My guess is that since atomic hydrogen is less massive than molecular...

du = 1/x dx sooo u/4 du...b/c...(1/4)*(ln(x)/x) dx

Homework Statement I am trying to find the following (marked in red) angle, I know that the radii to the points of contact make an angle θ with the horizontal. Homework Equations all angles of a triangle add up to 180 degrees. isosceles triangle, has two equivalent sides The...

could someone help me out here?

a=0 b+c+d=0 -2c=1 => c=-1/2 b+d=1/2 ==> b=d=1/4 T=l1/4g-1/2s1/4 but T= 2π (l/g)1/2 what i did is is correct?
