The most significant thing I have learned from this channel is not to be surprised by any new discovery, since it seems to be almost every week we are hearing of things being observed which were thought impossible. It really puts things in perspective regarding a healthy degree of uncertainty or skepticism. But it is the discovery, not the certainty, that keeps science interesting.

@@crawkn Absolutely. The more we know, the more we know we don't know. The process of discovery is endless for this exact reason, and it's why science is so fulfilling. I wish more in science would embrace your initial stance: "It's the discovery, not the certainty, that keeps science interesting". So many scientists are focused on certainty, which while valuable for industry, isn't what advances the field. Only by discovering new and heretofore unknown phenomena can we advance our knowledge.

As for the telescope thing, if that's what you're talking about then no because they're redshifted first of all, so that alone is a big no, and you can only see them through telescopes that run a certain time for more exposure otherwise they're not visible in real time.

The explanation of an O-type binary partner seems very strange for a couple of reasons. First and most confusing: an O-type star would have at least 10% the luminosity of WOH G64, and with the remarkable emission spectra of 30,000 K. Even if the surrounding dust were to absorb all the emitted light, its vastly increased temperature should show up as one of the dust lobes being brighter than the other. The second, and less strange, part is that O-type stars have very short life-spans, on the order of 10 million years. If that were the case, this would have to be a recent capture. It feels to me that it'd be more likely a black hole partner, but that would have very obvious gamma ray emissions so is also ruled out by lack of observed gamma rays near this star. What a mysterious star! I also can't believe that it could be 3000 solar radii in size, that's unimaginably enormous!
@stargazer5784
@stargazer5784 Ай бұрын
It's worth noting that all giant stars are relatively short lived, so a red supergiant paired with an O type giant isn't actually too far fetched. However, one would think that it would cause at least some IR emissions from the dust torus, even if entirely cloaked. Maybe, maybe not. The 3000 solar radii figure is just speculation of what it's original size may have been, while remembering too that red giants of such enormous proportions are essentially what have been called a 'red hot vacuum', because most of the star's visible structure is very tenuous in nature. The star doesn't really have a well defined surface or limb, as it were. Because of this, placing firm constraints on the radius becomes somewhat problematic. We can only say that at a given color/temperature, at a given distance, and with a given apparent magnitude, the radius should be at least so and so. With objects that are much closer, interferometric (aperture synthesis) measurements can be used to get a much more accurate measurement, but I'm guessing that this one is just too far away. Cheers!

You touch on this briefly, but we're not looking at the star itself. What we see is an oval cocoon of gas and dust around the star. The star itself is about 10 times smaller and would be a bright point in the middle of the cocoon. However, it is too dim or too much obscured to detect.

star core picks up mass or rotational speed, and the excess angular momentum dynamics cause the upper gases in the atmosphere to not be able to hold on gravitationally, so they get partially hurled away in two symmetric equatorial countervortices? that's my guess for that wobbly instability.
@DavidBrown-zp5vs
@DavidBrown-zp5vs Ай бұрын
The gravitational forces on the extremities of a star that large are going to be so much weaker compare to the central area, that with the fact that the star in the same area will be less dense means it make much more sence that the star wont be a nice round shape and it would be bulgey in places. Dont forget its ejecting mess out too, that would explain the stuff around it, its chaotic so it shouldnt form a stable spinning disk around the star.

I am a little confused. You had said in previous episodes that after 1.4 to 2.5 solar masses, the start will become a neutron start, but this big star has 40 solar mases and it is not a neutron star. Can you make an episode to resolve this apparent contradiction?
@ianstopher9111
@ianstopher9111 Ай бұрын
Neutron stars happen after collapse (such as in a supernova). The fusion reaction creates pressure that keeps a star like WOH G64 from collapsing. Once that pressure goes and there is core collapse then there are limits to how much mass can be held together. The neutron star is prevented from collapsing further by degeneracy pressure: which has an upper mass limit as you mentioned.

The end result neutron star, or black hole if the core mass is beyond about 3.2 solar masses, comes after the supernova, not during the red giant phase.

I wonder if a high spin rate could cause the stretched formations - we could be looking at it spinwards with the poles at each flattened end. If the star is massive and low density I'd imagine a high spin rate could cause clouds to escape at the equator, with less and less as you go to higher latitudes. That might account for the squashed shape of the clouds.
@jaymelton2663

I could also imagine a scenario where the plasma in the outer layers might pile up due to turbulence creating an imbalance in the star over time - once it reaches a certain tipping point, the entire blob is thrown off creating the large dip in luminosity.

2:20 I was very confused for a second, because your statement "A red giant star; a star that one day is going to contract and then go supernova". WOH G64 is a red supergiant, not a red giant. The difference between the two is whether they will go supernova or not (from what I understand). Red giants won't end with supernovae, just regular novae.
@stargazer5784
@stargazer5784 Ай бұрын
A lone red giant of relatively low mass, similar to that of our sun, won't go nova at all. It will just become a white dwarf at the end of it's life cycle. The term red giant is frequently used in a rather generic fashion because the physical parameters of these monsters varies so widely and we sometimes can't be sure of what they actually are. The same holds true for OB giants or supergiants.

An entire generation of extremely brilliant physicists, in the early 20th century, knew that hydrogen fusion was the only possible explanation for the energy output seen in stars, and the development of the H-bomb was the first well known example of that knowledge being put to the test. Given what is revealed about the composition of stars through spectral analysis, a tool that's PROVEN to be accurate, we know that hydrogen fusion, and the fusion of still heavier elements produced through stellar nucleosynthesis, are what drives the energy production and evolution of stars. There can be no other explanation. Get over it. You are speculating, in a very disrespectful fashion I might add, about things that are beyond your current level of understanding. However, it's never too late to learn something, if you really want to.

@@LordAugastus Scientists are very specific about exactly what they can and can't confirm, as well as their margins of error. It can be pretty boring reading, but you can find out exactly to what extent it's this guess that you claim.

Concerning your original question about size estimates, there's ALOT about observational astronomy that you know nothing about, and there's no shame in that. I'm not here to start teaching a basic astronomy class, nor is Anton. This isn't the place for it, and Anton assumes that you have at least some prerequisite knowledge of the subject. In short, if we know the distance, temperature, and luminosity of a star, we can place constraints on it's size. If something comes up that you're unfamiliar with, pause the video and look it up, such as with how stellar distances and sizes are measured. There's lots of free stuff to read out there, and some of it's written for the layman.

Quick question...what if stars do not explode or implode or reach "super nova"? I mean, we have never seen a star do any of these things. If it has never been observed, we can't call it scientific. It is pure speculation. Predictions made 100 years ago are being questioned today by new theories and scientific findings, such as those findings by the JWT.

How do stars get big if they burn more material away once's they start fusion. Maybe already formed they colide then some stars should have multiple cores

They don't gain mass, in fact they continually lose it throughout their lives. But they lose it to solar wind much more than to fusion. As stated it's due to heat. When their cores start to develop multiple layers of fusion, getting hotter the deeper they are, the stars puff up.

Yes. By mass the star bi253 (O2V) in the LMC has almost 100 solar masses, 1,175,000 its luminosity but only 13.9 times its radius. And since it is fusing hydrogen its also a "dwarf" star.

Supergiants are never the highest mass. The most massive stars are also the ones that eject matter the fastest through solar winds. So the most massive ones are the ones that just formed, or just merged with another. But agreed it should be clarified. I've seen people get very confused about this before.
