Mass-transfering Binary Star

[iamyourpopenow]

This is one of the most beautiful videos I've seen on youtube.

i have a question for you guys. how come at around the 1 minute mark, the binary stars start spinning clock wise instead of counter clock wise from the beginning?

[ramiro48]

from my relative understand of the nature of this, wouldn't the two of objects be at the same force equal and the transition be at the apex of the circle and not be at dominate mass? (this bothers me) this experiment can be duplicated with a soap bubble on a god damn sank!

You are thinking correctly and, in fact, the two stars are orbiting about each other rather quickly. However, I made the movie from a frame of reference (point of view) that is turning with exactly the same period as the orbit so that the stars appear to be almost stationary. From this point of view it is easier to study the dynamical behavior of the mass-transfer stream.

what I don't understand is how binary star systems spin so slowly? isn't there a lot of mass that would make a lot of gravity pulling the stars together, which means some force would have to keep them from colliding? the most common of these that I've seen is centripetal force (I'm not here to get into an argument about the spinning forces, you know what I mean). so how do they stay apart without spinning very fast?

What is the known distance between a mass transfering binary system? Would 886,700,000 miles be considered too close for a binary system? (On video) Whats the diameter in km of these binary stars? What is the distance between them?

[jet53man]

The video depicts two interacting "white dwarf" stars. Each has a diameter that is only 1% the diameter of our Sun, i.e., about 8800 km. The two stars are initially separated by only about 15,000 km. In our local region of the Milky Way Galaxy, a dozen double-white-dwarf binaries like this have been discovered. One of the nearest such systems is AM CVn (constellation Canes Venatici); it is about 750 light-years away from the Solar system, i.e., about 11 million billion miles away.

Hu jet53man, good video. So two binary dwarf stars (both mainly consist of Carbon and Oxygen and less than 1.4 solar mass) basically collide into one contact star? And what would happen if one of the sister stars was a red gas giant? My friend said the white dwarf would supernova (type Ia) if it's solar mass was more than 1.4? Is that true?

I do not think that the mass above would cause a super nova because those are created bye the core of a star using nuclear fuision with iron with out energy the sun implodes but two Binary stars collidng usaly makes 1 new star judging bye the stars in this video a red straggler the red staggler has lesss or double mass lumoisity and heat so if it were 2 neautron stars Yes they would explode

@jet53man you are amazing.

[Pimpmastahanhduece]

yea, its about a trillion miles just to get to pluto, under a lightday. and the nearest star is 4.5 light years.

How many modes must a star spin down

Before you call it spun down?

The answer, my friend, is blowin' in the stream
