- Confirmed means astronomers agree on what the object is. A candidate is a strong suspect that still needs more evidence.
- Groups pulsars by how fast they spin and what light they send out. Millisecond pulsars spin hundreds of times a second; some pulse in X-rays or gamma rays instead of radio waves, and rotating radio transients flash only now and then.
- The time for one full spin. The value in brackets is the number of spins per second (Hz).
- How much longer each spin gets with every second that passes. The pulsar slowly brakes as it gives away energy.
- An age estimate from how fast the pulsar spins and how quickly it slows down. It is a rough guide, not a measured birth date.
- The strength of the magnetic field at the surface, estimated from the spin and its slowdown. A fridge magnet is about 100 gauss (G); Earth’s field is about 0.5 G.
- The energy the pulsar loses every second as its spin slows. It powers the pulsar’s beams and winds. For comparison, the Sun gives off about 4 × 10³³ erg/s.
- How bright the pulsar is in radio waves at 1400 MHz, corrected for distance so that pulsars can be compared fairly.
- How much the gas between us and the pulsar delays its radio pulses. Larger values mean more gas along the way, which usually means a greater distance.
- How fast the object moves across the sky relative to the Sun. Motion toward or away from us is not included.
- The number of recorded glitches: sudden small speed-ups in the spin, thought to happen when the star’s inside suddenly drags its crust along.
- Objects linked with the pulsar, such as the remains of the supernova that created it, a glowing cloud blown by its wind, a star cluster, or the same source seen in X-rays, gamma rays or visible light.
- The time the object takes to circle once around its companion.
- How stretched the orbit is. 0 is a perfect circle; values closer to 1 mean a longer, thinner oval.
- The other object in the orbit, such as an ordinary star, a white dwarf or another neutron star.
- Worked out from the pulsar’s orbit. The orbit’s tilt is unknown, so the companion has at least the first value; the median is its most likely mass.
- How astronomers found the object or worked out what it is.
