What Is the Gravity Value on Neutron Stars?

Click For Summary
SUMMARY

The discussion centers on the gravity acceleration values on neutron stars and other celestial bodies. The commonly accepted gravity value on Earth is 9.81 m/s², while the value for the Sun is approximately 274.2 m/s², contradicting the claim of 1200 m/s². The relationship between gravity, mass, and radius is defined by the formula g = G (M/R²), where G is the gravitational constant. This formula illustrates that gravity is directly proportional to mass and inversely proportional to the square of the radius.

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.

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

bye
