Could some of these variable stars actually be nearby red dwarfs with very low luminosity - say less than one tenth of one percent of the luminosity of the Sun such that what would create a small change in luminosity of a more massive star would increase the luminosity by several fold? is it true that normally a dim red dwarf at the distance from us of the fairly nearby star "Sirius" cannot be seen with the naked eye (dimmer than magnitude 6) ?

@stargazer5784 4 ай бұрын

Valid questions. Distances to well observed stars like this one (since 1937 at least) are pretty accurately determined using parallax measurements and other methods, so the chances of this star being way closer than described are pretty much nonexistent. As to the second question, there are no naked eye visible red dwarfs that I know of.

@@existenceisillusion6528 I just finished a course on maxwells equations this spring so I can gladly explain that to you. I haven’t taken any quantum courses so I can’t give you any explanation there that is reliable, but as far as I’m aware the main difference is that since electrons have spin, they act equivalently to how an incredibly tiny loop of current would act under maxwells equations. The equation for electromagnetic force is F=q(E+V cross B), where q is electric charge, E is the electric field, and B is the magnetic field. V is the velocity of the object with charge q. Thus, the force is present either when there is any electric field present at the location of a charged object, pointing in the direction of the electric field for a positive charge or the opposite direction for a negative charge (the sign of q would be negative in that case and thus the force would be negative). The other situation in which force is present is when the charged object is moving through a magnetic field, in which case the magnetic force is perpendicular to both the velocity and the electric field direction, indicated in the equation by the cross product between V and B. It’s worth noting that a magnetic field is generated when an electric charge is moving, which is what makes the magnetic field in reality the same as the electric field from a moving reference frame. Really, it’s all the same electromagnetic field and electromagnetic force, but it’s useful to describe specific situations of that force and field as either magnetic or electric because they are present in different situations and behave differently. In the case of electrons however, since we know they are quantum particles with spin, in maxwells equations, that behaves equivalently to a tiny loop of current, which means that the charge q would have some velocity V, so in a magnetic field B an electron will experience a force as per those equations. I can’t explain this to you in terms of the equations of QED however, I started taking a class on partial differential equations but I dropped out before we got to the Schrödinger equation or anything like that, lol

@@Nosirrbro That's an interesting question, I'd not really analyzed it much, but I guess they remind me of children, hungry and changing their luminosity as they evolve, and the disc interaction and corresponding higher accretion rate and outbursts kind of like teenagers, volatile and unpredictable. Then like young adults, they are rearranging their surroundings, tearing some things down and making dust that will one day rebuild things in a new way. If they grow into G or K type stars, they're similar to contented adults. Other kinds of stars do too, for example how some people live loud and bright but burn out early like blue and white giants, and binary stars that in some cases are destructive to one another, or one overpowers the other and eventually destroys it (reminds me of my first husband), and in other cases they live calmly near each other. Then there are stars orbiting black holes. I think we've all met someone who is a bit like a black hole, insatiable and draining, and best kept at a distance. I'm interested to hear your analogies on the subject, if you like, and thank you for asking!

Nice start... but I don't like the final explanation... Why always colliding binaries and destroyed planets? We understand the beautiful mechanics of the two-body system expansion... Tidal forces help to maintain the stability of the system rather than causing its destruction (Unless the Lagrange effect takes place with a 3rd body). The luminosity change explanation is more simple with a restructure of the atomic fuel cycle requiring a lattice change in the star. Spectrometry must also consider element and chemical emission lines rather than black body emission given such a lattice change. Cheers! 🙂
