You can represent the life cycle of a typical smaller star like our sun with a series of five plastic globes illuminated by Christmas bulbs. Prior to igniting fusion and becoming a main sequence star, a contracting protostar will reach hydrostatic equilibrium at around 3,500 °C.

Heavy stars turn into supernovae, neutron stars and black holes whereas average stars like the sun end life as a white dwarf surrounded by a disappearing planetary nebula.

from p.284 of Star Names, Richard Hinckley Allen, 1889. A star's life cycle varies depending on its mass. These dead stars are full of energy, and stay that way, after the death of an average star. By: Austin, Lauren, and Rebekah Honors Earth and Space Science Period 1 A white dwarf by definition is “a relatively small, dense star at the end of its cycle, which generates little or no energy and has contracted to its dense state. All-stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant. FLUX is the amount of energy that falls into a certain area Apparent Magnitude

It is a supergiant star, distinctly red in colour, located at an approximate distance of 643 light years from Earth. Order most items by 12:15pm PT on 6/15 with U.S. Express Shipping* » Vega, Alpha Lyrae (α Lyr), is a bright white main sequence star located only 25 light years from Earth. Wega, less correctly Vega, originated in the Alfonsine Tables from the Waki of the Arabs, Bayer having both titles; Scaliger, Waghi; Riccioli, Vuega vel Vagieh; and Assemani, Veka. South Florida PBS Recommended for you This star is in the Alpha Quadrant, near the Denobula Triaxa system. Betelgeuse, Alpha Orionis, is the second brightest star in Orion constellation and the ninth brightest star in the sky. As stars progress through life, their size, luminosity and radial temperature change according to predictable natural processes.
All stars, however, follow roughly the same basic seven-stage life cycle, starting as a gas cloud and ending as a star remnant. This section will describe those changes, focusing on the life cycle of the Sun.

Red Giant: Over the course of its life, a star is converting hydrogen into helium at its core. The largest stars have the shortest lives, and can last a few billion, and even just a few million years.

The history of the star: Vega. If this star would have an apparent magnitude of 1, the fainter star would have an magnitude greater than 1 (like 2 or 3) The upper star is drawn larger only to represent the fact that it is brighter, not necessarily that it is bigger.


Vega (also known as Alpha Lyrae and the Vegan system) is a star system in Federation space, located almost 8 parsecs (25 light-years) from Earth, where it is visible as the brightest star in the constellation of Lyra. the brighter star (the upper star). [A scanned copy can be viewed on this webpage] Alpha (α) Lyra, Vega, is a pale sapphire star in the Lyre. Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula.
