Pulsar (a type of neutron star) PSRJ1748-2446ad spins at 24% the speed of light. Also, it is very dense, so it has a significant gravitational field that doesn't let you fly off into space if you are on the surface.

 

So, would the relativistic effects add up if someone was on the surface? Also, in the perspective of the star, will it age (and eventually die) much later because of its own gravity and velocity?

I thought the passing of time would be a greater difference between earth and being on the surface of a pulsar spinning at 24%the speed of c, but for 1 second on earth only 1.03 seconds would pass for some travelling at 24%c, "I think".

 

CLOCK 1: 0% speed of light (Earth)

 Speed (relative to Earth): 0 kilometer/hour
 Length of second (relative to Earth): 1.00 second

CLOCK 2: 25% speed of light
 Speed (relative to Earth): 25% the speed of light
 (75,000 km/sec or 47,000 miles/sec)
 Length of second (relative to Earth): 1.03 seconds

CLOCK 3: 50% speed of light
 Speed (relative to Earth): 50% the speed of light
 (150,000 km/sec or 93,000 miles/sec)
 Length of second (relative to Earth): 1.15 seconds

CLOCK 4: 75% speed of light
 Speed (relative to Earth): 75% the speed of light
 (225,000 km/sec or 140,000 miles/sec)
 Length of second (relative to Earth): 1.51 seconds

CLOCK 5: 99% speed of light
 Speed (relative to Earth): 99% the speed of light
 (297,000 km/sec or 185,000 miles/sec)
 Length of second (relative to Earth): 7.09 seconds

Einstein is 17 years old.

CLOCK 6: 99.99999999% speed of light
 Speed (relative to Earth): 99.99999999% the speed of light
 (299,999.997 km/sec or 185,999.998 miles/sec)
 Length of second (relative to Earth): 19.6 hours

Also psrj1748-2446ad has a binary companion, Which may fuel it and extend its life and increase its speed, But fuel is fuel and as we know when you run out of fuel things come to a stop, Or at lest stops radiating. Perhaps becoming another "dark" object.
