Alkaid is the brightest star in the constellation Ursa Major, while Mizar is a fainter star in the same constellation. Alkaid is a hot, blue star that is much more luminous than Mizar, which is actually a double star system.
A star that is very hot but dim is a?
That might be a white dwarf.
If neutron stars are hot why arent they very luminous?
Neutron stars are hot because they are formed from the remnants of massive stars that have exploded. However, they are not very luminous because their small size leads to a low surface area for energy emission. Additionally, their intense gravitational pull can trap a significant portion of the emitted energy.
Is a star's outer layer hot and dense?
Yes, a star's outer layer, called the photosphere, is hot and dense. This is where most of the visible light and heat emitted by the star originate. The temperature and density of the photosphere vary depending on the type and age of the star.
What is a hot self-luminous shpere of gas?
star
What is a star in space?
A star is a luminous globe of hot gas that makes energy.
What is betelgeuse is that a hot or cool?
Betelgeuse is a red supergiant star located in the constellation Orion. It is a very luminous and relatively cool star, with a surface temperature of around 3,500 Kelvin.
How can a cool star be more luminous than a hot star?
Luminosity is related to temperature and distance.A cool and thus less luminous star would be brighter than a more luminous star at a greater distance.Our Sun is a relatively cool star in comparison to say Rigel, but because it is closer it appears more luminous and brighter.
What is the temperature of cygni?
The temperature of Cygni, or specifically the star Deneb (also known as Alpha Cygni), is estimated to be around 8,500 Kelvin. This makes it a very hot and luminous star compared to our Sun, which has a surface temperature of about 5,500 Kelvin.
What type of star is cursa?
Cursa is a binary star system consisting of a B-type star and a fainter star. The B-type star is a hot, blue-white star that is more massive and luminous than the Sun.
What is the difference between luminous and non luminous?
-A non-luminous flame is when the air hole of the Bunsen burner is closed but a luminous flame is produced when the air hole is opened.-A luminous flame has an outer of orange colour and an inner of blue. A non-luminous flame has an outer of blue and an inner of orange.-A luminous flame produces soot while a non-luminous does not produce soot.-A luminous flame is weak and unsteady. A non-luminous flame is strong and steady.-A non-luminous flame is very hot while a luminous flame is not too hot.
Is a luminous flame a hot flame?
All flames are hot
What do you call a tiny and very hot star?
It is called a neutron star.
What class type of star is spica?
Spica is a binary star system consisting of two massive stars. The primary star in the system is a blue subgiant star, while the secondary star is a slightly smaller blue main-sequence star. Both stars are hot and luminous.
What is one fact about a star?
They are very hot.
Is a luminous gas flame hot?
Yes, but not as hot as the blue one.
