Rane faze nastanka zvijezda u maglici Rozeta ; Early stages of star formation in the Rosette Nebula

Zvijezde u nastanku su od izričite važnosti u proučavanju svemira te ćemo u ovom radu proučavati kompleks Rozetu koja je znanstvenicima odavno zanimljiva jer sadrži mnogo mladih zvijezda koje kriju mnoge tajne u nastajanju, za život kakav mi poznajemo, neophodnih izvora zračenja energije. Kompleks Rozeta se nalazi na udaljenosti od ∼ 1.5 kpc od Zemlje, a procijenjena starost iznosi 1.6 ± 0.5 Myr. Za ovaj smo rad iskoristili podatke sa svemirskog teleskopa Spitzer te smo krenuli od kataloga s 18216 izvora zračenja te smo proučavanjem pozicija zvijezda na raznim boja-boja i boja-magnituda dijagramima identificirali 1304 mladih zvjezdanih objekata, od toga 141 mladih zvijezda klase I i 1163 mladih zvijezda klase II. Također smo zaključili kako je jugoistočni dio kompleksa mlađi od središnjeg dijela kompleksa, odnosno od skupa NGC 2244 koji se nalazi u samom središtu kompleksa Rozeta. ; Stars in the making are of extreme importance when studying the universe, so in this paper we will be looking into the Rosette Complex, which has been very interesting to the scientists for a long while because it contains numerous young stars which hide many secrets in the formation of sources of energy radiations that are necessary for life as we know it. Rosette Complex is located at a distance of ∼ 1.5 kpc from Earth and the estimated age is 1.6 ± 0.5 Myr. For this paper the data from the Spitzer Space Telescope have been used and we started from the catalog with 18216 sources of radiation and by studying the position of stars on various color-color and color-magnitude diagrams, we have managed to identify 1304 young stellar objects, out of which 141 are young stars of Class I and 1163 young stars of Class II. We have also concluded that south-east region is younger than its central part, i.e. the cluster NGC 2244, which is located in the very centre of the Rosette Complex.
