- Astronomers observing a distant star system have identified what may be the most massive neutron star ever discovered.
- Neutron stars like the newly discovered J0740+6620 are the remains of dead stars.
- Stars run for millions or billions of years but eventually run out of fuel.
- Then they become one of the three
- Smaller stars become white dwarfs (like Sun)
- Larger stars collapse into black holes
- Stars with mass equivalent to 8 and 29 solar mass become Neutron Stars
About J0740+6620
- MSP J0740+6620 is about 2.14 times more massive than sun.
- But it is less than 15 miles in diameter.
- The mass is determined using a principle called “Shapiro time delay”.
- Because of the extreme density of MSP J0740+6620 it might soon collapse into a black hole.
