Superstar Duet in Eta Carinae
Ғылым және технология
A gem from NASA Astrophysics. Eta Carinae is a binary system containing the most luminous and massive star within 10,000 light-years. A long-term study combined data from NASA satellites, ground-based observing campaigns and theoretical modeling to produce the most comprehensive picture of Eta Carinae to date. New findings include Hubble Space Telescope images that show decade-old shells of ionized gas racing away from the largest star at a million miles an hour, and new 3-D models that reveal never-before-seen features of the stars' interactions.
Located about 7,500 light-years away in the southern constellation of Carina, Eta Carinae is actually two massive stars whose eccentric orbits bring them close every 5.5 years. Both produce powerful stellar winds, which enshroud the stars and stymy efforts to directly measure their properties. Astronomers have established that the brighter, cooler primary star has about 90 times the mass of the sun and outshines it by 5 million times. Its smaller, hotter companion weighs in at about 30 solar masses and emits a million times the sun's light.
At closest approach, or periastron, the stars are 225 million kilometers apart, or about the average distance between Mars and the sun. Astronomers observe dramatic changes in the system during the months before and after periastron. These include an ebb and flow of X-ray light; the disappearance and re-emergence of structures near the stars detected at specific wavelengths of visible light; and even a play of light and shadow as the smaller star swings around the primary.
During the past 11 years, spanning three periastron passages, a NASA group has developed a model based on routine observations of the stars using ground-based telescopes and satellites. According to this model, tthe winds from each star have markedly different properties: thick and slow for the primary, lean and fast for the hotter companion. The primary's wind is especially dense, carrying away the equivalent mass of our sun every thousand years. By contrast, the companion's wind carries off about 100 times less material than the primary's, but it races outward as much as six times faster.

this is the only type of superstar duet I care about.
I always knew Eta Carinae was a monster, but the stellar wind being so dense as to obscure the star itself... that's just nuts. And of course, the "little" companion is 30 solar masses... o_O
Holy shit! That 3D model is amazing. Thanks again SpaceRip!
Nice and spectacular at the same time !
Just simply mind blown. Nice videos and info as always.
Excellent video as always!
FREAKING EPIC!!!!!! thank you!
Space Rip you are brilliant. I truly look forward to your releases.
fantastic duet..
2020 sounds so futuristic
Now that is fascinating. I've been wondering about what was going on in Eta Carinae for the last 2 years since I first saw it. Stunning system, with fascinating physics.
It is mind blowing binary systems are my love its 2019 looking forward to Feb next year great vid 👌🌿🐞®
Terrific visuals.
Amazing video!
Great Job!
Mind. blown.
Awesome.
Beautiful name-Eta Carinae.
This video is intergalcticleyvawesome fascinatingly cool
that why science is bloody brilliant!

Are the creators of these videos still alive? I know maybe you don't have millions of viewers but some of us are big big fans of yours. You have no idea how many times a week I am checking SpaceRip although lately not so much...
Hundreds of millions of degrees. I can't even try to comprehend just how hot that is. I wonder if that creates new gases or something we can't even imagine.

'new gases'? how are these gases composed? 1 proton? 2 protons? 3 protons? well 1 proton is hydrogen, 2 is helium, and 3 is lithium... we know what element comes out when we add protons up to 118 protons.... and those are radioactive metals... and up to 92 in the periodic system, nothing can form naturally, and everything after 92 is artificially made on earth.

Isn't that hot. If anything, colder is cooler (pun intended). A extreme high temperature is possible, but 0K (zero kelvin) is pretty much physically impossible as of yet. Also, creating things require pressure as well as temperature. 2 protons in a space of a meter wont fuse no matter how much temperature is added, unless they have an unlikely collision.

By using spectroscopy techniques. Analysing the light given off allows them to figure out things like the temperature, the mass and the chemical elements present in the stars, amongst other things.
I did not understand what this video said
All the talk of pretty colors and clouds and not 1 word as why this even happens.. The 'Primer fields explains all of this with Magnetism.
5 million times brighter than sol, it would so cool if those were a bit closer to the earth =)
could a planet exist in such a system?

maybe with a crazy orbit that somehow keeps it far from the star/s, especially at peri-astrolon
seems that the two stars could either slam into one another or get so close that one or both could be flung out of it's orbit. This is just from looking at the models at the 1 minute marker.

pull is depended on mass but centrifugal force is corrected by gravity and centripetal force is generated simultaniously as in a geroscope and as in spin stabilization.to discuss time in such events is unreasonable but the pull of gravity here in massive and certain

look at pictures of nuclear explosions the horns of matter show there same as the stars.They stike the ground and is plasma but it behaves like a fluid.
Nothing against the minute physics guy but can we get the regular host back? Somehow he makes it so easy to listen.
The great star for seven days will burn, Cloudy will make two suns appear. The Big Mastiff will howl every night. When the great Pontiff will change terrain." (Nostradamus: Centuria II; Quartet 41) Current version: - "The great star" is a Supernova that will explode with overwhelming force ... The total duration of these events is usually one year, but its maximum brightness would be only seven days ... And put to choose, I would bow by Eta Carinae, the biggest star in real size of the Constellation of Carina (La Quilla). It has 150 solar masses and is accompanied by Eta Carinae B, of 90 solar masses ... According to astronomers they are about to make "Hipernova", the most impressive cosmic burst ... - It will shine a lot even during the day, despite the brightness of the Sun. Astronomers believe that this could happen soon, and "It will appear in the sky like two Suns" ... - "The Great Mastiff will howl every night": They are the Media, Written press, Internet, KZread, Radio and Television that will not fail to report such an astronomical event day or night ... - "When the Pope must move away from Rome", for serious political events that will bring him to America ... Could he refer to his last trip? ... -There is a prophecy of Garabandal, in which the visionary Conchita González announces "The illumination of consciousness", which begins with a great brightness in the sky that predisposes people to see their own conscience and says that "It will be as if two stars collide ": The extreme brightness of the star will be so strong that the fear of death clearly shows good and bad actions committed throughout life ...

0:57/3:57 These 2 Companion STARS about to Super-explode as this Hypernova: if such an EVENT should occur within the near Future, and thus directly observable by this present Generation, will IT not be Classified as another very special and extremely distinctive type of supernova, separate from all the prior ones that had occurred near Earth, or elsewhere, in another star system remote from Us, yet detectable by Our instruments? May IT not be an Utter SINGULARITY supernova-hypernova, not seen or seeable anywhere else, in our Galaxy, but not, perhaps in other areas of the Universe?

So much left unexplained. The music is obnoxious, and "Carinae" properly rhymes with "tiny" in the way English-speaking astronomers pronounce Latin. What are the lines at 4689 Å and 4815 Å ? They look familiar to me.

***** No, the first "a" in there is indeed pronounced like the a" in "alive". It's "ee-ta" or "eat-a" with the short a sound. That's the seventh letter of the Greek Alphabet, Η η, and I'm Greek.

George Perakis Not in English, where the primary pronunciation is long a, as in "hay". I just verified it in the American Heritage Dictionary of the English Language. If we were speaking in Greek, maybe. But we aren't.... The error made by the narrator was to pronounce "Carinae", the genitive in Latin of "Carina" as if it were not "Carinae" but "Carina", the nominative. That was wrong.
