Asymptotic giant branch - Wikipedia The asymptotic giant branch (AGB) is a region of the Hertzsprung–Russell diagram populated by evolved cool luminous stars.This is a period of stellar evolution undertaken by all low- to intermediate-mass stars (about 0.5 to 8 solar masses) late in their lives.. Observationally, an asymptotic-giant-branch star will appear as a bright red giant with a luminosity ranging up to … Astronomy 1 Midterm 3 Study Ch. 16-18 Flashcards | Quizlet The arrows on each protostar's curve on the diagram's indicate that _____. ... Rank the HR diagrams based on when each stage occurs, from first to last. The diagram at the left represents the Sun (or any other one-solar-mass star) as a hydrogen-burning main-sequence star, with spectral type G and one solar luminosity. ...

List of nearest bright stars - Wikipedia This list of nearest bright stars is a table of stars found within 15 parsecs (48.9 light-years) of the nearest star, the Sun, that have an absolute magnitude of +8.5 or brighter, which is approximately comparable to a listing of stars more luminous than a red dwarf. Right ascension and declination coordinates are for the epoch J2000.The distance measurements are based on …

Red supergiant - Wikipedia Red supergiants (RSGs) are stars with a supergiant luminosity class (Yerkes class I) of spectral type K or M. They are the largest stars in the universe in terms of volume, although they are not the most massive or luminous. Betelgeuse and Antares are the brightest and best known red supergiants (RSGs), indeed the only first magnitude red supergiant stars. Main sequence - Wikipedia When a protostar is formed from the collapse of a giant molecular cloud of gas and dust in the local interstellar medium, ... (On the HR diagram, the evolving star moves up and to the right of the main sequence.) Thus the main sequence represents the primary hydrogen-burning stage of a star's lifetime. Star - Wikipedia A star is an astronomical object comprising a luminous spheroid of plasma held together by its gravity.The nearest star to Earth is the Sun.Many other stars are visible to the naked eye at night, but their immense distances from Earth make them appear as fixed points of light. The most prominent stars have been categorised into constellations and asterisms, and many of the …

On an hr diagram a protostar would be. Sun - Wikipedia The Sun is the star at the center of the Solar System.It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radiation, and is the most important source of energy for life on Earth.. The Sun's radius is about 695,000 kilometers (432,000 miles), or 109 times that … Hertzsprung–Russell diagram - Wikipedia The Hertzsprung–Russell diagram, abbreviated as H–R diagram, HR diagram or HRD, is a scatter plot of stars showing the relationship between the stars' absolute magnitudes or luminosities versus their stellar classifications or effective temperatures.The diagram was created independently in 1911 by Ejnar Hertzsprung and by Henry Norris Russell in 1913, and … Nova - Wikipedia A nova (plural novae or novas) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star (hence the name "nova", which is Latin for "new") that slowly fades over weeks or months. Causes of the dramatic appearance of a nova vary, depending on the circumstances of the two progenitor stars. All observed novae involve white … Chapter 17 Flashcards | Quizlet Protostar 3. Main-sequence Star 4. Red Supergiant 5. Supernova 6. Neutron Star. Provided following are various elements that can be produced during fusion in the core of a high mass main sequence star. Rank these elements based on when they are produced, from first to last. ... This is the HR diagram for stars in a 12-billion-year-old globular ...
