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 supernova?
Eta Carinae and the Great Eruption Someday the massive star Eta Carinae will explode as a supernova! But that likely won’t happen for millions of Earth-years. And, in the meantime, this star is fascinating to astronomers as a pre-supernova, or a star approaching its death throes. Such stars do interesting things.
What caused one of the stars in Eta Carinae to suddenly become very bright?
Astronomers became aware of Eta Carinae in 1847, when the giant eruption that ejected its nebula also made it the second-brightest star in the sky after Sirius. According to their study, Eta Carinae’s brightness is likely caused by the dissipation of a dust cloud positioned in front of it (as seen from Earth).
How do I find my Eta Carinae?
Once you have found the Southern Cross move about 24 degress West (to the right) where you will find NGC 3372 (the Eta Carina Nebula). Near its centre there is a very bright orange star – this is Eta Carina. In 1843 this star was the second brightest star next to Sirius.
How old is Eta Carina?
around 3 million years old
Eta Carinae B is speculated to be 1 million times brighter than our sun. Both stars are enveloped by a cloud of gas and dust known as the Homunculus nebula. The exact age of these stars is hard to determine, but most speculate that they are around 3 million years old.
How far is Eta Carinae from Earth?
7,502 light yearsEta Carinae / Distance to Earth
What type of star is Procyon?
A binary star system, Procyon consists of a white-hued main-sequence star of spectral type F5 IV–V, designated component A, in orbit with a faint white dwarf companion of spectral type DQZ, named Procyon B. The pair orbit each other with a period of 40.84 years and an eccentricity of 0.4.
What type of nebula is the Orion Nebula?
diffuse nebula
The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula with a greenish hue and is situated below Orion’s Belt. It is one of the brightest nebulae, and is visible to the naked eye in the night sky.
How do Hypergiants form?
Creation of Hypergiant Stars. All stars form in clouds of gas and dust, no matter what size they end up being. It’s a process that takes millions of years, and eventually the star “turns on” when it starts to fuse hydrogen in its core. That’s when it moves onto a period of time in its evolution called the main sequence …
Can you see Eta Carinae?
Its location at around 60°S in the far southern celestial hemisphere means it cannot be seen by observers in Europe and much of North America. Located between Canopus and the Southern Cross, Eta Carinae is easily pinpointed as the brightest star within the large naked eye Carina Nebula.
What constellation is Eta Carinae in?
constellation Carina
Eta Carinae, also called Homunculus Nebula, peculiar red star and nebula about 7,500 light-years from Earth in the southern constellation Carina and now known to be a binary star system. It is one of a small class of stars called luminous blue variables.
