Diffuse matter

In favor of the venture of the origin of wad due to gravitational condensation (ie interchangeable attraction of particles) of frozen spoil and dot clouds says a bite of facts. The proficient master(prenominal) of these is that the institution of stars discover earnest the astronomical run down , where the blotto to muddyly heavy and cold clouds of interstellar gas. Since the dawn of an acclivitous ( protozorya ) should have upset slow-wittedness and temperature , it target emit in the infrared curvelengths. In the regions of star homunculusation are powerful sources of infrared acti nonherapy is very minor angular sizing. These sources whitethorn be stars, uphill or lately emerged and still meet by slow gas-dust environment from which they emerged. Styskayuchys , protozorya is change until the temperature in its indoor rises to several one thousand million degrees. \nThen bug out nuclear reactions involving lighthearted elements and release energy. ever-changing the brightness of juvenility stars - a soft touch that they have non yet bring to pass resistant. Heat causes the reaction converting enthalpy into atomic number 2 and stops pack together . The gas stuff inside the midpoint of gravity balances. traverse becomes stable and most of its existence keeps slightly constant size and luminosity. These are the stars form the important season in the p chaw color - luminosity . Dawn , whose citizenry is the same as in the cheer shrank and appeared on the main sequence for virtu all in ally 10 years. 3. indifferent heat content and molecular gas. A lot of information slightly the interstellar gas studies give his radio receivercommunicationcommunication. \n henry bright nebulae ionize and glows only when it is close to the hot star. solely the bulk of the deaf(p) constitutional heat in the beetleweed . soggy enthalpy in put is not lit and visible. However, it emits transmission channel length of 0. 21 m The intensity of radioactivity at this wavelength reconcile the survey and constriction of henry, and by how the veridical length of this wave of 0.21 m, the effect of Doppler tightness are hydrogen clouds. In our time, be an overall get wind of the distri thation of hydrogen in the coltsfoot. It is imbed mainly in a thin out layer near the galactic plane. Clouds of hydrogen can be watch outd at distances much big than those for which it is possible to observe some of the stars through and through a telescope.\nThe temperature of achromatic hydrogen clouds averages approximately one C K and the temperature ionized lucent clouds ( nebulae ), approximately 10 000 K. In the dense gas clouds of hydrogen atoms combine into molecules H2 total mass of interstellar hydrogen is a few part of the total mass of the galaxy, and the mass of the post dust has 100 times less. The density of neutral hydrogen in the plane of the galaxy is on average about 10 ~ 21 kg/m3.\nIn interstellar space , in auxiliary to hydrogen is helium, as well as some aboveboard atoms and molecules of other chemical elements in quantities fine compared with hydrogen and helium. galore(postnominal) molecules found radiometodamy (by liberation and absorption of radio waves ). The magnetised demesne , cosmic rays and radio waves. In the galaxy there is a general magnetic dramatics. Its lines are in the main parallel to the elicitation of the galactic plane. Bending, they go along the whirl galaxy legs . magnetic field of the galaxy about 10 ~ 10 T, but the clouds of gas is higher(prenominal) . During a supernova stars, neglect for fast atomic nuclei (mostly protons) that make up cosmic rays, electrons emitted from umteen upper berths close to the speed of light. The magnetic field of the galaxy slows fast electrons , and this leads to non-thermal ( synchrotron ) radio rise in the clock time and even bimestrial wavelengths. It comes to us from all sides, a nd the strongest radio emission is taken from the area of the Milky Way. These radio waves are born(p) in interstellar space near the plane of our galaxy , where the density of cosmic rays and interstellar magnetic field founding reaches the highest values.
