Of course, times have changed. At that time, Baidu Encyclopedia had only one volume. Maybe the initiator saw my answer and made some repairs. But the astronomical skills are too poor, and the entries in Baidu Encyclopedia are really full of loopholes.
Attach the entry link first: /link? URL = f 5 uvm 5 ro y2 xwqg 7 rzmt 7 swdes 1 z 9 x 8 scvojr 1 tl2 iceqgajkmqxh 8 _ qhiqripsaxox 5 wteg 3 gcfxcpzagodgjk
Let's talk about some fundamental absurdities first:
Only the right ascension was given, not the right ascension. I just want to say that the geographical location of Shanghai is east longitude 12 1. Is there any reason not to give latitude 3 1?
The apparent magnitude is 9.95, which is 4300-6900 light years away. Can the absolute magnitude be -72? According to the conversion between visual magnitude and extreme magnitude, it is easy to get that the absolute magnitude of this star is around -2. Also, it says that it is 700,000 times larger than the sun, and the absolute magnitude is only -9. X, how about making up the data or at least rolling it flat?
The mass is 2000 times that of the sun. If the mass of a star is more than 1.20 times that of the sun, the strong stellar wind on the surface will throw away the material on the surface until the mass drops to a stable value of 1.20 times. As for the mass of R 136a 1 is about 140 times, why it is slightly larger than 120 times, and whether the observation error, theoretical model or celestial evolution model need to be modified has aroused discussions in academic circles. It's a good thing here, it's over an order of magnitude at once. To be sure, a lot of science and nature will not mention the Nobel Prize.
The discovery time is 20 12. Are you kidding? 20 12 found a non-southern celestial pole ten stars? Change it to 1850. This little light spot can be found in any public telescope with hundreds of pieces on the market now.
Spectral-B5V, how can such a massive star be an O star? You said yourself that the surface stability is 87,200 K. Oh, by the way, shouldn't a model be built before O at such a high temperature? Never mind the details, this V means dwarf! Take a blue dwarf for comparison. The spectral belly of B 1III (β Centauri) is subgiant, and its diameter is only more than twice that of the sun. You are a V-shaped dwarf of the same class as the sun, with a diameter of 60,000 times that of the sun? Ha ha.
The O-type superstar is in the upper left corner of Herotto.
It is no more than 6900 light years away from the earth, and it may have exploded tens of thousands of years ago. The light of this star does not travel at the speed of light. Oh, my God.
It is repeatedly emphasized in the picture that this is a blue super super Supergiant star, but what about the attached picture of Baidu Encyclopedia? Indicates that the dog CX star is red. Also, the VY of Canis Canis is 8.5, so how can a star 10 be about three times brighter than other stars in WWT?
Ok, spit out some small places:
"cx, the largest star dog found at present, is about 30 times that of dog vy". What is 30 times that of dog? Mass or volume? The most basic physical knowledge and language description ability are not available.
"A small lamp can be seen in the scale diagram of the constellation Vi Canis (the second largest star discovered by human beings) and the sun"-let me help you correct it. The last sentence should be "There is still a small lamp". Style teaching cannot escape.
"4300-6900 light years" is false just by looking at the numbers, and the triangular parallax method has no such accuracy at this distance. Such a celestial body covered with clouds cannot be measured by a spectrophotometer.
"cx cma, as a Lambert Supergiant star, has extremely unstable shape and amazing luminosity change". The luminosity varies greatly, so there is fog. In addition, please explain why V-dwarfs can have strong pulsation. Hydrogen fusion in massive stars is still very stable.
It is different from other special Supergiant star, which is more common in conjoined or multi-star systems, because it is a single star without a companion-what is a conjoined star? The context of brain tonic should be "double star". All right.
"People speculate that its diameter is roughly three times that of vy cma, and some people speculate that it is 2 billion times larger than the sun. Another view is that it is just an ordinary blue star, and its diameter is only 1000 times that of the sun. The high luminosity may be caused by the nearby canis major star, which means that the Canis Canis is 6,543.8 billion times brighter than the sun, but this is unlikely. " -Two billion times the sun? Holy shit, how many light years is the diameter of a star? Also, please explain why the measurement error of diameter can be eight orders of magnitude, and the celestial luminosity of the same surface temperature is directly proportional to the square of diameter. So the error of photometric calculation should be 16 orders of magnitude? What concept? 40 and so on! What concept? The apparent brightness of the sun is -26.7, etc. For the stars of 13.3, the telescope should have the caliber of 152, and there is nothing too big to take off. The high brightness is close to Ursa major VY…… ................................................................................ The reason why Kaiyang is the brightest in the Big Dipper is because it has a companion star named "Fu" (Ursa major 80). It is proved that the binary star system can improve the luminous ability and undoubtedly won the Nobel Prize. In addition, you said that its distance is much worse than that of Canis Vi, which supports particle optical binary stars. What does this have to do with its luminous ability? Finally, the luminosity is 1 billion times that of the sun, which is impossible. Well, it's too small. Didn't you say that the ultimate magnitude of human beings is -72, at least 1000 billion times that of the sun (the sun is 483, and the corresponding magnitude of 1 000 billion times is 20, etc.). ).
"The current state of dog cx is very unstable, and a considerable amount of substances are erupting into the surrounding clouds." Didn't you say it was the main sequence star?
"Astronomers observed with the Hubble Space Telescope predict that it will eventually become a super supernova in the next 200,000 years (or it died tens of thousands of years ago, or it may not be a star)." Hubble's photo? Photos of the tarantula nebula formed by Haishan II (η) are all in Baidu. In addition, the super supernova is another Nobel Prize-level discovery.
"The quality of the dog cx is enough to form a black hole, and the quality is extremely high." A black hole with a mass of 2000 times is just a little brother in the black hole.
Full of loopholes is an adjective, but here the word "hundred" seems to be more than just an imaginary number. The full text can be said that there is not a word that can't be found. Obviously, this is an April Fool's joke (in the best understanding) of an amateur who is only at the entry level in both scientific literacy and writing. The network is characterized by the diversity and inclusiveness of information, but everything has two sides, and some dirty contents have eroded the scientific field that should be serious and sacred. I hope the landlord can apply what he has learned, analyze and think more, and experience and sublimate himself in the network environment.
