Is Eta Carinae hotter than the Sun?
The temperatures are greatly debated. Beta Carinae A has been estimated to have around 9.400 to 35.200 K – this is between 1.6 to 6 times hotter than our sun. Beta Carinae B has surface temperatures of around 37.200 K or 6.4 times hotter than our sun. Eta Carinae A is classified as a luminous blue variable LBV star.
How much bigger is Eta Carinae than the Sun?
As of January 2009, we now know about some other really big stars. One is called Eta Carinae. It has a size about 800 times that of our Sun, a mass about 100 times that of our Sun, and is about 4,000,000 times brighter than our Sun.
What is special about Eta Carinae?
The most notable feature of Eta Carinae is its giant eruption or supernova impostor event, which originated in the primary star and was observed around 1843. In a few years, it produced almost as much visible light as a faint supernova explosion, but the star survived.
How hot is Eta Carinae?
In 2005 astronomers studying far-ultraviolet spectral observations of Eta Carinae made by spacecraft found that it is a binary star system with an orbital period of 5.54 years. Its A component has a temperature of about 15,000 K; its B component, about 35,000 K.
Will Eta Carinae become a black hole?
Once the star dies, Woosley says, its core will likely collapse to form a black hole, although one rotating too slowly to make a relativistic disk and a GRB.
Is Eta Carinae a white dwarf?
This open cluster was discovered by Lacaille in 1751, is located approximately 479 light years from Earth and is visible to the naked eye. The brightest star in the cluster, as the name indicates, is Theta Carinae, a blue-white dwarf.
Will Eta Carinae go supernova?
Eta Carinae is expected to become a supernova in the future, but the great eruption event was merely a bright outburst.
What if Eta Carinae exploded?
Fortunately, Eta Carinae is far away, at least7,500 light-years from Earth. If it explodes, most of its energy will bescattered or absorbed in the vast emptiness of space.
