exotic star

Since most of the animals are not exotic star attractions, they would be hard to place.

Also, the SALT telescope allows scientists to study the rapid brightness changes in exotic stars.

And no matter how far I traveled, no matter how many exotic star systems I explored, I knew I might never see its like again.

A quark star or strange star is a hypothetical type of exotic star composed of quark matter, or strange matter.

An exotic star is a compact star composed of something other than electrons, protons, and neutrons balanced against gravitational collapse by degeneracy pressure or other quantum properties.

Exotic stars are largely theoretical, but observations released by the Chandra X-Ray Observatory on April 10, 2002 detected two candidate strange stars, designated RX J1856.5-3754 and 3C58, which had previously been thought to be neutron stars.

An electroweak star is a theoretical type of exotic star, whereby the gravitational collapse of the star is prevented by radiation pressure resulting from electroweak burning, that is, the energy released by conversion of quarks to leptons through the electroweak force.
