“all are of the dust, and all swing to clean again” Ecclesiastes Birth and Death of stars in our Galaxy Have “star’s nurseries ” and “star’s retirement homes ” in the Milky Way their own particular favored places or are they appropriated haphazardly ? Tal Kopler and Matan Markovich Tshernihovski School, Netanya, Israel .

Slide 2

Birth and Death of the stars: 1. Conception A Star is conceived from billows of gas. Right now of conception it enlightens the remainders of it’s mother, the cloud. HII-locales (of the ionized Hydrogen) encompass all the youthful stars = star’s nursery. Brilliant mother-cloud around the infant star is the first exhalation of the star-infant. This a piece of the star’s life is short – a great many years. After this beautiful conception, the star lives quite a while discreetly by gradually processing the essential hydrogen in her stomach. Stars with huge mass (O,B) have high temperature in the middle => high temperature of the surface (more blue) and radiance (vitality misfortune), along these lines their life is splendid and short, concerning every saint. Stars with low mass (G,K,M) have low temperature inside, low vitality discharge and surface temperature (more red), in this way their life is long and faint.

Birth and Death of the stars: 2. Demise A star kicks the bucket after it completes the asset\'s majority of its mother’s essential matter (H ,He,…). In its last minute, the star blasts (the last shriek - “star’s agony”) and launch to space its outer layer. The catapulted gas shape a Planetary Nebula around stellar leftover (white diminutive person). The cloud grows and dissipates quick (millions years). Notwithstanding, the white diminutive person gradually loses its internal warmth, and gradually diminishes after billions of years. For huge mass stars last blast launches all stellar mass (SN=Super Nova) and structures a stellar leftover (neutron star or dark gap). Planetary Nebulae and SN-remainder from Sky-Watch information Library:

Slide 4

Stellar Evolution and stellar hues Most of the stars are in the condition of “Main Sequence” – like a congested road. On the Herzsprung-Rassel outline of “luminosity versus color” short-matured monstrous stars with blue shading and high splendor are arranged in the upper left corner. In inverse, since a long time ago matured stars with low mass with red shading and low splendor are arranged in the base right corner.

Slide 5

Milky Way Galaxy Evolution Our Galaxy was conceived from a moderate turned gas cloud. The Galaxy\'s mass speaks the truth hundred billion Sun. In the first place stars conceived in this cloud billions of years prior as globular groups. They contained a huge number of stars. Today, in these bunches stays just low mass red stars with long life compass. Cosmic system gas cloud gradually broken down into a level plate (diffusive power kept the turned gas to crumple to the middle) Spiral arms in the gas circle – the best place for conception of new stars (enormous, blue, brilliant – are among them)

Slide 6

Why Do We Research the Distribution of Stars in the Milky Way ? There are numerous billions of stars in the Galaxy, with inventories of them officially made. The area of stars with known age in Galaxy could give us intimations about the Milky Way’s development. Keeping in mind the end goal to better comprehend the life-cycle of stars in our Galaxy, we should first comprehend where are their introduction to the world and demise places.

Slide 7

Strategy of Research Method: to test disseminations in our Galaxy for distinctive sorts of articles: Very youthful stars quickly after conception, with HII-districts around them - first exhalation of star-child . Exceptionally old globular bunches of red stars. Planetary nebulae – last yell of the as of late dead stars. Open Clusters of extremely youthful stars in the Milky Way Source of information: “AstroTop” program , Blossom of Science, Israel Coordinates : right rising, declination

Slide 8

Detailed Research: Globular Clusters of Old Red Stars Source: Catalog of 151 Milky Way globular groups. For what utilization: Position of the globular groups on the sky. Conclusion: old GC are circulated anyplace with focus to Center of Galaxy Milky Way

Slide 9

Detailed examination: Open Clusters of Young Stars Source: Catalog of 1638 Milky Way open groups For what utilization: position of the open bunches on the sky. Conclusion: youthful open bunches concentrate to level circle of the Milky Way Galaxy with no uncommon center to the Galaxy\'s Center

Slide 10

Detailed Research: HII Regions Around Young Stars’ Formation Place Source: Catalog of 313 HII districts of the northern sky. For what utilization: Position of HII-areas on the sky Conclusion: HII locales around youthful stars concentrate to level plate of the Milky Way Galaxy with no unique center to the Galaxy\'s Center.

Slide 11

Detailed Research: Planetary Nebulae Around Dying Stars Source: Catalog of 2113 Planetary Nebulae - positions on the sky Conclusion: Planetary Nebulae around biting the dust stars partition into 2 bunches: One is in the level plate of the Milky Way Galaxy and the other is scattered on the sky. There is focus in the Galaxy\'s Center.

Slide 12

Summary result Summary dispersion demonstrates that infant and kicking the bucket stars so as their nebulae have diverse position in our Milky Way, reflecting stellar and Galaxy development

Slide 13

Future Work To proceed with work with another gathering of Milky Way protest (pulsars, dark gaps, Supernova remainders, X-beam stars, …) To proceed with this work looking at Milky Way pictures in distinctive parts of electromagnetic spectra, reflecting diverse gatherings of articles emitters (radio, infrared, optical, UV, X-beam).

Slide 14

Future Work with Robotic Telescopes of Sky-Watch Images of the closest cosmic systems in distinctive discharge lines: Emission lines of HII – areas (youthful stars) Emission lines of Planetary Nebula (old stars) To test for closest worlds – is it likewise valid for the
