REZIME

Mnogi objekti u kosmosu koji su suviše hladni i slabog sjaja, da bi bili registrovani u vidljivoj svetlosti
mogu se sa lakoćom uočiti u infracrvenoj oblasti. Takvi objekti su hladne zvezde, oblaci i čestice oko
zvezda, magline, braon patuljci i planete.

Univerzum je jedan veoma širok pojam, a zvezde su samo mali deo tog, nama nepoznatog prostora. Braon
patuljci čine još manji skup i veoma se malo zna o njima. To su ”nesuđene” zvezde (” zvezde u pokušaju”
); u njihovim jezgrima nije postojala gustina materije potrebna za otpočinjanje nuklearne fuzije.

Po izjavi naučnika Mejna, braon patuljci su slaba veza između velikih planeta poput Jupitera i malih
zvezda, kao što su crveni patuljci. Braon patuljci su nedovoljno istraženi i predstavljaju jedan od izazova
moderne astrofizike.

Kljuĉne reĉi: braon patuljci, zvezde, ostali patuljci, temperatura, masa, jezgro .

SUMMARY

Many objects in the Cosmos that are too cold and faint to be registered in the visible light and they can be
easily observed in the infrared field. Such phenomena are called cold stars, clouds and particles around
stars, nebule, brown dwarfs and planets.

The Universe is a very broad term, and the stars are just a small part of it, and the space is actually
unknown to human kind. Brown dwarfs are pretty unknown group and we know very little about that
physical appearance. They are called ,, the stars in the attempt " because in their cores there are not enough
density of matter, which is required for the process of initiation of the nuclear fusion.

Accordin to the statement of the scientist Maine the brown dwarfs are weak link between large planets
like Jupiter and small stars such as red dwarfs. Keywords: brown dwarfs, stars, the other dwarfs,
temperature, mass, core .
