QuestionAnswer
neutron star a small highly dense star composed almost entirely of highly packed neurtons
pulsar a source of short precisely time radio bursts. Believed to be a spinning neutron star
lighthouse model the explanation of a pulsar as a spinning neutron star sweeping beems of radior radiation
pulsar wind the flow of high energy particles that carries most of the energy in a spinning neutron star
glitch sudden change in a period of a pulsar
magneter class of neutron stars that have exceedingly strong magnetic fields
millisecond a pulsar with a period of a millisecond
gravitational radiation as predicted by general relativity expanding waves in a gravitational field that transport energy through space
singularity the object of zero radius into which the matter in a black hole is believed to fall
black hole a mass that has collapsed to such a small volume that its gravitational strength prevents the escape of all radiation.
event horizon the boundary of the region of a black hole from which no radiation may escape
Schwarzchild radius the radius of the event horizon around a blackhole
Kerr black hole solution to equations of general relativity that describes properties of rotation around a black hole
ergosphere the region surrounding a rotating black hole when it could not resist being dragged around a black hole
time dilation slowing of moving clocks or clocks in a strong gravitational field
gravitational redshift the lengthening of the wavelength of a photon due to its escape from gravitational field
x ray burster an object that produces repeated bursts of xrays
quasi periodic oscillations a high speed flickering in the radiation from an accretion disk spiralling inward
gamma ray burster an object that produces a sudden burst of gamma rays
soft gamma ray repeater object that produces repeated bursts of lower energy gamma rays
hypernova the explosion produced as a very massive star collapses into a black hole

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
