What is Spica luminosity?
Spica shines at magnitude 1.04, making it the brightest light in Virgo. It’s the 15th-brightest star visible from anywhere on Earth. It’s virtually the same brightness as Antares in the constellation Scorpius, so sometimes Antares is listed as the 15th and Spica as the 16th brightest. No matter.

What color is Vindemiatrix?
Vindemiatrix. This star has its name that comes from the word harvester. It means the action of the vintage. It has a magnitude of 2.8 and has a totally yellow color.
What stage of life is Spica in?
The primary Spica star is halfway between a blue subgiant and a blue giant on the evolutionary stage. Its spectral class if B1 III-IV.
How far is Minelauva from Earth?
What does auva mean?
Auva is the medieval name of Delta Virginis, a star in the zodiac constellation of Virgo. The name is derived from Arabic عوى ((c)awwa’), meaning “barking (dog)”.
Why is Virgo named Virgo?
Virgo is one of the 48 constellations first cataloged by the Greek astronomer Ptolemy in the second century. Its name means “virgin” in Latin. It is an ancient constellation. The Babylonians knew it as “The Furrow”, representing the goddess Shala’s ear of grain.
What is the shape of Virgo?
Virgo is the second-largest constellation. In Greek mythology, it represents both the goddess of justice and the goddess of the harvest. The main stars of Virgo form a lazy Y shape.
Why does the luminosity of a star increase with temperature?
Luminosity increases with increasing surface area for stars with the same surface temperature. Star y and star t have the same luminosity. Star t has a higher surface temperature. Therefore star y is larger. For objects with the same luminosity, high surface temperatures must be offset by low surface areas.
How are luminosity, temperature and surface area related?
In the law of Stefan and Boltzmann, there are three quantities: luminosity, surface temperature, and surface area. To find one of these, you must know the values of the other two. The questions in this exercise take advantage of two stars having an identical value for one of these three.
Is the color of a star an accurate measure of its surface temperature?
If you study this plot, or one of the interactive blackbody radiation demonstrators we used in the last lesson, you can prove to yourself that the color of a star provides a fairly accurate measurement of its surface temperature.
