Exotic stars in the Universe | Boson star | Preon star | Planck star | Quasi star | Strange star

Here i have explained about some possible exotic hypothetical stars in our universe.

0:00-Intro
An exotic star is a hypothetical compact star composed of something other than electrons, protons, neutrons, or muons, and balanced against gravitational collapse by other quantum properties.

0:42-Boson star

A boson star is a hypothetical astronomical object that is formed out of particles called bosons  force carrier particles but also consist of Helium-4 nuclei, which are bosons.
Examples of bosons are fundamental particles such as photons, gluons, and W and Z bosons (the four force-carrying gauge bosons of the Standard Model), the recently discovered Higgs boson.

For this type of star to exist, there must be a stable type of boson with self-repulsive interaction; one possible candidate particle is hypothetical "axion"  candidate for the dark matter. Boson stars may have formed through gravitational collapse during the primordial stages of the Big Bang.

It is theorized that unlike normal stars (which emit radiation due to gravitational pressure and nuclear fusion), boson stars would be transparent and invisible. Like a black hole, a boson star would absorb ordinary matter from its surroundings, but the transparency means this matter (which likely would heat up and emit radiation) would be visible at its center .

2:08-Preon star

Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons.Protons and neutrons can be further broken down , they're both made “quarks.” As far as we know, quarks can't be broken down into smaller components, making them the smallest . But scientists think quarks can be further broken into another particle preons , these are point particles, sub-components of quarks and leptonsAfter big bang original stars were made of these sub-subatomic particles, with most gradually becoming made of sub-particles, and then particles. Preon stars would be extremely tiny, ranging in size somewhere between a pea and a football Packed in that tiny area would be the mass of the Moon much denser than neutron stars .

3:18-Planck star

Planck star  is a hypothetical astronomical object, theorized as a compact, exotic star, that exists within a black hole's event horizon, that is created when the energy density of a collapsing star reaches the Planck energy density. The quick
repulsion arises from the  heisenberg uncertainty principle . This repulsive energy is strong enough to stop the collapse of the star to become a singularity . if Planck star exist, it would be small compared to an atom but larger than the planck length .

4:02-Quasi star
A quasi-star is a hypothetical type of extremely massive and luminous star that may have existed early in the history of the Universe. Unlike modern stars, which are powered by nuclear fusion in their cores, a quasi-star's energy would come from material falling into a black hole at its core.

4:28-Strange star

A strange star  is a quark star made of strange matter and strange matter or strange  quark matter , is quark matter  containing strange  quarks.
