What type of star is Miaplacidus?
A1IIIBeta Carinae / Spectral type
How old is Beta Carinae?
260 million years
Physical properties. The stellar classification of A1 III suggests this is an evolved giant star, although Malagnini and Morossi (1990) rated it as an A2 IV subgiant star. It has an estimated age of 260 million years.
How far is Miaplacidus from Earth?
Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 29.34000 which means Miaplacidus distance from Earth is 111.17 light years away from Earth or 34.08 parsecs.
How old is Miaplacidus?
Either way, with an estimated age of only 260 million years, Miaplacidus has already stopped fusing hydrogen in its core and, in another 2-3 million years, it will evolve into a red giant.
How far away is Miaplacidus?
At a distance of 111 light years, with a temperature that from various sources averages 9100 Kelvin, Miaplacidus shines with the light of 210 Suns, which yields a radius 5.85 times that of the Sun.
What type of star is Beta Carinae?
What color is Eta Carinae?
Eta Carinae A is classified as a luminous blue variable (LBV) due to the distinctive spectral and brightness variations. This type of variable star is characterised by irregular changes from a high temperature quiescent state to a low temperature outburst state at roughly constant luminosity.
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.
What does Carina look like?
The Carina Nebula is a large bright nebula that surrounds several clusters of stars. It contains two of the most massive and luminous stars in our Milky Way galaxy, Eta Carinae and HD 93129A.
Is Carina a star?
Carina is home to several double stars and binary stars. Upsilon Carinae is a binary star with two blue-white-hued giant components, 1,600 light-years from Earth. The primary is of magnitude 3.0 and the secondary is of magnitude 6.0; the two components are distinguishable in a small amateur telescope.
Is Carina the brightest star in the North?
Carina, (Latin: “Keel”) constellation in the southern sky that stretches from about 7 to 11 hours right ascension and at about 60° south in declination. Its brightest star is Canopus, the second brightest star in the sky, with a magnitude of −0.7.
Is there a constellation with 9 stars?
The Carina constellation consists of 9 primary stars and has 52 Bayer/Flamsteed designated stars. It’s alpha star, Canopus, is not only he brightest star in the constellation, but the second brightest in the night sky (behind Sirius).
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.
Is Eta Carinae visible from Earth?
The pair is about 7,500 light-years from Earth. Once an important star to navigators, Eta Carinae is no longer visible to the naked eye on Earth. There is still a lot that’s unknown about Eta Carinae, including how large the star system was before the Great Eruption.
Who is carrina?
Carina was a Krylorian slave of the Collector, acting as his aide and servant. She eventually grew tired of her master’s cruel treatment of her and, in an attempt to kill him, she tried to harness the power of the Power Stone, but she could not handle its extreme power and was quickly killed.

What is the spectral type of the star Miaplacidus?
Miaplacidus has the stellar classification A1III, indicating a giant star appearing white or bluish white in colour. A 1990 study estimating stellar temperatures, radii, and luminosities based on spectrophotometry and trigonometric parallaxes listed the star as a subgiant of the spectral type A2 IV.
Where is Miaplacidus located in the sky?
Miaplacidus is the 28th brightest star in the sky. It is only slightly fainter than Shaula in the constellation Scorpius, Gacrux in Crux, Bellatrix in Orion, and Elnath in Taurus, and it just outshines Alnair in Grus, Alnilam and Alnitak in Orion, and Alioth in Ursa Major.
Is Miaplacidus turning into a red giant?
Either way, with an estimated age of only 260 million years, Miaplacidus has already stopped fusing hydrogen in its core and, in another 2-3 million years, it will evolve into a red giant. Miaplacidus has a mass 3.5 times that of the Sun and, as it evolved away from the main sequence, it has expanded to a size of 6.8 solar radii.
What is the surface temperature of the asteroid Miaplacidus?
Miaplacidus has a mass 3.5 times that of the Sun and, as it evolved away from the main sequence, it has expanded to a size of 6.8 solar radii. With a surface temperature of 8,866 K, it is 288 times more luminous than the Sun.
