gravity value on neutron stars

[delplace]

Gravity acceleration value depend on planet and stars mass. On the earth, the well known average value is 9.81 ms-2. On the sun, I read 1200 ms-2; is it true ? does exist a curve giving values depending on mass ?

Not from what I find. I get something like 274.2ms-2.

does exist a curve giving values depending on mass ?

Gravity is linearly proportional to the mass of the object and inversely proportional to the square of its radius. Something like this:
g = G \frac{M}{R^2}

thank you. I will verify on internet why this value of 1200 ms-2
