In the development of substantial stars, what is the meaning of the temperature 600 million K? in ~ which stage in a sun-like star"s life is its core the least dense? will certainly the Sun ever before turn into a brown dwarf? Why or why not? (SA) In general, as stars go through the last stage of post-main sequence evolution they will lose mass in the procedure of stable down into their final state. Explain the mass-loss procedure and the final state that the star because that a short mass star. (SA) compared to our Sun, a common white dwarf has actually Isolated main-sequence stars as substantial as 10 come 12 time the massive of the sun may still regulate to stop going supernova. Why? refer to the figure above. In ~ what numbered point on the graph above does the helium speed occur? What is a planetary nebula? Mass transfer in binaries occurs as soon as one huge swells to reach the describe the number above. What is the name of the path in between the points labeled 13 and 14? How have Hubble images revised our check out of the structure of planetary nebulae, and also even the potential for the sunlight to end up being one? (SA) The brightest stars in a young open cluster will certainly be noting the turnoff mass in a star cluster permits you to recognize its What inevitably pressures a star prefer the sunlight to evolve far from gift a key sequence star? The order of evolutionary step of a star prefer the sun would be key Sequence, giant, planetary nebula, and also finally: What is the unusual result of mass carry in the Algol binary system? You observe a low-mass helium white dwarf. What can you conclude? the brighter Sirius A weighs 3 solar masses, yet the white dwarf Sirius B is only about one solar massive implies: In globular clusters, the brightest stars will be practically all the carbon-rich dust in the aircraft of the galaxy originated in What spectral kind of star the is still around formed many recently? said hydrostatic equilibrium come the star"s mass, composition, and also evolution off the main sequence. (SA) i m sorry is provided observationally to identify the period of a star cluster? i beg your pardon stars in globular swarm are believed to be examples of mergers? A star is on the horizontal branch that the H-R diagram. Which statement is true? What spectral kind of star that is still roughly formed longest ago? i beg your pardon of the following finest describes the evolutionary track adhered to on the H-R diagram because that the most substantial stars? just as a low-mass key sequence star runs the end of fuel in that core, it actually becomes brighter. Just how is this possible? The Roche lobe of a star in a binary star mechanism The most famous instance of a much more massive warm star orbiting with a more evolved yet presently less massive red giant is the eclipsing binary What is a common age for a globular cluster? What properties of a star swarm is offered to identify its age? A high-mass star dies more violently than a low-mass star because: during the hydrogen shell burning step The brightest stars in aging globular clusters will be What temperature is necessary to fuse helium into carbon? which of the following elements contained in your body is NOT created in the cores of stars during thermonuclear fusion? which of the adhering to is true concerning planetary nebulae? The "helium flash" wake up at what stage in stellar evolution? What is the common age for a globular cluster linked with our Milky Way? together a 4-10 solar massive star leaves the main sequence ~ above its means to coming to be a red supergiant, the luminosity describe the number above. What is the name of the path in between the points labeling 10 and 11? A solar fixed star will certainly evolve turn off the key sequence when When a star"s inward gravity and outward push are balanced, the star is said to be refer to the number above. What is the name of the path between the points labeling 8 and 9? In a reasonably young star cluster, if the most enormous stars space swelling up right into giants, the least enormous stars are describe the figure above. What is the surname of the path between the points labeled 11 and 12? describe the figure above. What is the name of the star labeling 10?a red huge branchb Mc The main point contracts, increasing the temperature and increasing the size of the an ar of hydrogen shell-burning.d red supergiants favor Betelguese and Antares.e the main sequence turnofff Roche Lobe.g because that a short mass star, the hydrogen fuel is exhausted and also the star begins to fuse helium. Once this wake up the star expands into a red giant. Eventually the helium is exhausted and the external layers the the star are ejected together a planetary nebula, leaving a tiny, hot white dwarf behind.h Helium build up in the core, if the hydrogen burning covering expands.i red giantj the is the temperature required for carbon fusing right into heavier elements.k horizontally rightl No, the is enormous enough come ignite hydrogen blend and reach the main sequence, i m sorry brown dwarfs cannot. Just objects of much less than 8% that the Sun"s mass space brown dwarfs.m because they can additionally have solid stellar windsn is, in terms of the star"s gravity, that "zone of influence."o instead of simply spherical shells, we recognize that plenty of if not most planetary nebulae space bipolar ejections; frequently the figure of a "ring" originates from the dual lobes coming directly at us and away native us. The elaborate structure suggests that magnetic areas are molding the nebulae, and that maybe the rotation and perturbation of a companion star may be regularly involved. It might be that just binary stars can create these spectacular stellar shrouds.p around the same mass and a million times greater density.q main Sequencer still evolving towards their ZAMS positionss it is burning both hydrogen and helium.t ageu the ejected envelope, regularly bipolar, of a red large surrounding a stellar core remnantv Hydrostatic equilibrium way that the inward pressure of gravity, a product of the star"s mass, is exactly balanced by the outward radiation pressure of the thermonuclear reactions; as lengthy as the hydrogen it is provided is abundant, this balance deserve to be maintained, and the star is secure on the key sequence. As soon as the main point helium contents grows, and the hydrogen burning covering expands, this extra radiation temporarily overwhelms gravity, and also the star starts swelling right into its giant stage that evolution.w it builds up a main point of inert helium.x Some are spherical, yet most have bipolar structure.y the generates an ext heat and its core at some point collapses very suddenly.z the luminosity that the key sequence turn-off pointaa remains roughly constant.ab that the collapsed companion transferred mass come Sirius white asymptotic huge branchaf planetary nebulaag blue stragglersah low-mass Oaj white dwarfak 10-12 exchange rate yearsal that is part of a binary star red 12 exchange rate yearsao the star grows more luminous.ap hydrogenaq a helium white dwarfar 100 million Kas 9at horizontal branchau in hydrostatic equilibrium.av huge blue stars in ~ the optimal left on the H-R diagram.
