Extreme Binaries

Automatic TRANSCRIPT

Hip. How you doing? I'm doing well. It is finally spring as in. I can go play in the garden up there in Vancouver Island think Ryland. Yeah things are great. The weather is absolutely gorgeous and same thing. I have been out in the garden. The the only downside the robins get up at like four in the morning and they're you know they're breeding at this point to the Chirp Chirp Chirp and so I have one that found the the the really likes the acoustics right outside my room and so I've been getting up at four in the morning and then I have to go and get up and I have to call the window and then I try to get back to sleep and then I can't get back to sleep until you. Ivan haven't been getting a lot of sleep because robin has been singing his little heart out every morning really loud right outside my window. So hopefully he'll find a girlfriend and get lost until then yeah. It's pretty funny but spring. I mean you can't you can't go wrong. That is awesome so we're familiar with regular binary stars two stars orbiting each other simple. Of course the universe has come up with every combination of things orbiting other things and this week we look at some extreme examples are Pamela solicitous. Figure this out. What is a binary star so a binary star is a announced that that needs plural because a binary system is to? Who'S SEPARATE STARS? So a binary star is a system that exists in two stars and they can come in just about any kind of combination of regular star. Compact object Advanced Star Baby Star and they form a whole myriad of different ways. They can either a rise out of a single collapsing molecular cloud where they clapsed into their individual solar system by side-by-side or they can gravitationally get caught up together through some activity in their advanced lives. So when you're looking at a system statistically it's most common that it formed like that but they didn't have to right right and we can talk about that later on but I'm sort of imagining. That's her standard formation gigantic cloud of gas and dust that swirling around and you get like instead of all polling into the middle it pulls into two separate like what are the dynamics. Why doesn't it all just turn into one big star in the middle? Why how can you get multiple stars orbiting around each other so you actually have to fragments in the same molecular cloud? Okay gravitate pulling together and it happens to be that these fragments are close enough that the orbit one another different facts can bring them closer and closer over the years but they formed from two distinct fragments in the same like cloud and the fact that molecular clouds is fragmenting is how we end up with separate stars so the fragmentation is an unusual. These two are close enough that they got caught up in each other's gravity. And so then the vast majority of these situations you end up with some amount of stuff like a stars worth amount or mostly a red dwarfs amount of stuff but every now and then you end up with an extreme amount of stuff. These are very large blobs of gas and dust. And sometimes you just end up with two regular blobs that interact in ways. That are extreme. So we talk about extreme binary stay. We're GONNA talk about a whole lot of different combinations. So it's not just necessarily the amount of material that went into the star and the rain that it took but in fact these stars can interact with each other in really weird ways and 'cause really bizarre effects that we can see okay so so let's sort of break this down. Then when as you define extreme then we've defined binary to stars orbiting each other and start can be all kinds of things so let's define extreme. Give me sort of Sirte classifying. The kinds of extreme things that can happen so so when I'm talking extreme events I I am talking about things that radically 'cause upheaval. In the life of a star that could only happen because this is a binary system that any singular star with not undergo these kinds of well really bad millennia
