A Q-Star, also known as a grey hole, is a hypothetical type of a compact, heavy neutron star with an exotic state of matter. [1]

9 relations: Black hole, Compact star, Exotic matter, Exotic star, Neutron star, Preon star, Q-ball, Quark star, Stellar black hole.

Black hole

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it.

Christmas and holiday season

The Christmas season, also called the festive season, or the holiday season (mainly in the U.S. and Canada; often simply called the holidays),, is an annually recurring period recognized in many Western and Western-influenced countries that is generally considered to run from late November to early January.

Compact star

In astronomy, the term "compact star" (or "compact object") refers collectively to white dwarfs, neutron stars, and black holes.

Exotic matter

In physics, exotic matter is matter that somehow deviates from normal matter and has "exotic" properties.

Exotic star

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

Neutron star

A neutron star is the collapsed core of a large star which before collapse had a total of between 10 and 29 solar masses.

New Year

New Year is the time or day at which a new calendar year begins and the calendar's year count increments by one.

New Year's Day

New Year's Day, also called simply New Year's or New Year, is observed on January 1, the first day of the year on the modern Gregorian calendar as well as the Julian calendar.

New Year's Eve

In the Gregorian calendar, New Year's Eve (also known as Old Year's Day or Saint Sylvester's Day in many countries), the last day of the year, is on 31 December which is the seventh day of Christmastide.

Preon star

A preon star is a theoretical type of compact star made of preons, which are "point-like" particles conceived to be subcomponents of quarks and leptons.

Q-ball

In theoretical physics, Q-ball is a type of non-topological soliton.

Quark star

A quark star is a hypothetical type of compact exotic star, where extremely high temperature and pressure has forced nuclear particles to form a continuous state of matter that consists primarily of free quarks, which can be modeled using the Calabi–Yau manifold.

Stellar black hole

A stellar black hole (or stellar-mass black hole) is a black hole formed by the gravitational collapse of a massive star.
