How hot is Zubeneschamali?

12,300 KBeta Librae / Surface temperature
Indeed, the name Zubeneschamali, the northern one of the two, comes from an Arabic phrase meaning “the northern claw,” that of the Alpha star meaning “the southern claw.” Zubeneschamali is a hot “main sequence” (hydrogen fusing) class B (B8) dwarf star with a surface temperature of close to 12,000 Kelvin, double that …

Which star has the highest surface temperature?

Type O stars
Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins.

Which star has a surface temperature of 9000 K?

A-type stars
properties. In stars of spectral type F, the lines of neutral atoms are weak relative to those of ionized atoms. The hydrogen lines are stronger, attaining their maximum intensities in A-type stars, in which the surface temperature is about 9,000 K. Thereafter, these absorption lines gradually fade as the hydrogen…

What is the magnitude of Beta Librae?

2.61Beta Librae / Magnitude

Why is Beta Librae green?

There seems to be no generally accepted explanation for why some observers see it as green. The small periodic variations in the magnitude of Beta Librae suggest the presence of a companion star which is not directly observable from Earth. However, it is categorized as a single star.

Why is Libra called Libra?

They gave the constellation its present name. To the Romans, Libra stood for the scales of justice. They pictured the scales being held high by Astraeia, the goddess of justice.

Which stars have the lowest surface temperature?

Spectral types are a measure of the surface temperatures of stars and are letter designations: O, B, A, F, G, K, and M. Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins. On the other extreme, type M stars have the lowest surface temperatures and can be as cool as 3,000 K.

What is star surface temperature?

The surface temperatures of A-type stars range from 7,400 K to about 10,000 K; lines of hydrogen are prominent, and these stars are white. F-type stars are yellow-white, reach 6,000–7,400 K, and display many spectral lines caused by metals.

What star has a temperature of 6000K?

Others stars appear blue, such as Sirius, the Dog Star. Sirius has a surface temperature of around 15000K. Our Sun is an average yellow star, with a surface temperature of about 6000K.

Which star has highest surface temperature?

Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins. On the other extreme, type M stars have the lowest surface temperatures and can be as cool as 3,000 K.

What is the surface temperature of Beta Librae?

Properties. Based upon the features of its spectrum, Beta Librae has a stellar classification of B8 V, making it a B-type main-sequence star. It is about 130 times more luminous than the Sun and has a surface temperature of 12,300 K, double that of the Sun.

What is the temperature of Beta Centauri?

The Hadar/Beta Centauri system is around 41.700 times brighter than our sun. Beta Centauri Aa and Ab have been estimated to have surface temperatures of around 25.000 K, this means that both stars are 4.3 times hotter than our sun.
