Great show. Minor nit-picky comment. As I'm sure you know, you need the luminosity and spectral type to place a star on main sequence and get an assumed mass. With only one you might be looking at a red giant or brown dwarf (as in the video) that isn't primarily powered by fusion hydrogen into helium. The point here is that "Red Giants" are cooler then many main sequence stars but burning their fuel much faster so much more luminous, contradicting what you said in the video. I'm sure your trying to keep it simple, I've just market that test question wrong enough over the years that the distinction bugs me.

@badastronomy 10 жыл бұрын

Tristan Matthews That's true... but in this case, they examined nearby stars which had known parallaxes, so the luminosities were known. :) I wrote about this star and how this was done when it was announced: when www.slate.com/blogs/bad_astronomy/2014/06/11/the_brown_dwarf_limit_astronomers_have_found_the_smallest_star_known.html

@tristanmatthews9509 10 жыл бұрын

***** The parallaxes lets you calculate the luminosity off of the apparent brightness of the star, so it makes life really easy, but you need to measure both the luminosity and the spectral type to place it on the main sequence. The video asserts something like "The higher its surface temperature is, the more mass it has, because more massive stars....", with a nice little "Hotter = More massive", while this is true for main sequence stars its not true in general. Basically you need L and C (x and y coordinate) to place it on the HR diagram you can't do it with only one.

@tristanmatthews9509 10 жыл бұрын

Tristan Matthews Hmm I keep re-reading this and I feel like it comes across as though I'm trying to pick a fight, and I'm really not. Just making the point that Betelgeuse is Red (its surface is much cooler then the sun.), but much more massive.

@KingBrooklynman 10 жыл бұрын

Sort of. Technically earth could be considered a failed star, too. To be a star you need to have enough mass that you've pulled in to create fusion. The sun managed to do so, but didn't take in everything around it, obviously. What was left was able to find a stable orbit and clear its neighbourhood (for the most part) and become the planets. Jupiter has a fair amount of mass, but isn't massive enough to have been able to create fusion or really get that close. The earth even less so.

@LordMarcus 10 жыл бұрын

Ben Putnam So, this new star, though smaller than Jupiter, has more mass than Jupiter, enough to (probably, anyway, as noted in the video) undergo sustained fusion?

@StormwaterIsOneWord 10 жыл бұрын

Lord Marcus Yes.

@KingBrooklynman 10 жыл бұрын

Yeah, but just barely. It's the "smallest star" as it's at the lowest threshold for having enough mass to sustain ongoing fusion. At least ongoing enough that we can still see it, though it is only 42 light years away. There very well may be other *slightly* smaller stars that are farther away, but they either burned out before we got to see them, or they're too dim for us to see currently.

If that 'smallest star' can fit inside Jupiter then what kept Jupiter from becoming a star or even a brown dwarf?

@traeumerich 7 жыл бұрын

Say say that the smallest star is more massive than Jupiter, that means it has more heavy elements in it. For fusion to happen at considarable amounts it needs high temperature and density. The threshold is about 5% of the suns mass, and Jupiter has only about 0.1%.

Is there any good reason why this channel exists? That is, separately from the main SciShow channel. I really tried to get used to the new hosts, but they just don't work for me. It's obvious they were only chosen for convenience and not ability. And this guy somehow managed to make an incredibly interesting discovery sound incredibly boring. But my whining aside, what IS the reason this channel exists? I can't think of a single reason why you would split SciShow in half by "Space" and "Not space". It obviously wasn't to showcase host talent. Was it to increase production output? Not very plausible considering how much Hank cares about quality over quantity. And yet here it is. Effective science communication is all about the communicator, not the science. The science is available anywhere. Sacrificing that effective communicator component, you're left with bland hosts giving you blandly presented information. And it's not just that I want Hank to do everything. I don't. He's not the only (or even the best) educational communicator on KZfaq. That award likely goes to Emily Graslie. But whatever. I'm ranting. I'm going to get flamed by feminazis for even *vaguely implying* that Caitlin Hoffmeister is anything but a goddess anyways, so whatever.

I believe that they created this channel because there is a lot of space related science news and stuff going on and they wanted to be able to focus on it more. Also the reason that there are a lot of comments defending and praising Caitlin is because that in her first few videos there were a lot of negative comments saying that she shouldn't host because her appearance didn't conform to the standards of a few random youtube commenters.

@kaiajallai5167 10 жыл бұрын

And why should there not be a separate channel for space? There are tons of things to talk about regarding space. Not that other things they cover don't have tons to talk about, but they themselves obviously are interested in it. So why not? I for example really enjoy a separate channel where they can center only around space as I am a fan of this particular topic. But that aside, I think I remember form somewhere that the reason was that there was a lot of space-talk on the main show and a lot of viewer wanted to hear more about space. So you put 1 and 1 together and get this new channel. Regarding the hosts it depends on the person I guess. I like them and I also get the interesting information. And why should you be attacked? Most of these so called "feminazis" you refer to are here because of the way people talk about Caitlin (mainly about her looks). Also... the guy in this video is a guest host. He is an astronomer and writer/blogger. en.wikipedia.org/wiki/Phil_Plait I like him also. And if you read peoples comments, they do too.

If my memory is correct (which is a big if) this channel started a couple months after the failed attempt to fund SciShow through Subbable, and right around when they started putting ads in. I don't think Hank wanted SciShow Space - I think it was required by his sponsors to increase viewership. The attitude of Hank towards the new male host (can't remember his name) further hints that he is not pleased with this channel. But that's just a theory. ... A game theory!

That's actually very close to what I see on the internet from people who legitimately believe that. I have to congratulate you on your amazing success at emulating to behavior of people on the internet.

I like this host. He wasn't quite as animated, but he talked a lot slower and more clearly, so I was able to follow the explanation a lot better than usual. Good job :)

I love the "it's only 40 light years away" relatively speaking it's close but it might as well be on the other side of the universe for us to get closer. Time to get a bigger Hubble up there

I think an important notation for this episode is size not in physical demotions like radius, but mass or how much it contains inside of it. you can theoretically have two stars of the same mass that have different densities and they will have a different radius.

My man, Phil Plait! I was a bit sad that CC Astronomy was finished, but it was a great surprise to see that the Green brothers still hold you dear in their hearts, just as we do. Hope to see your awesome, secret (Death Star like, I'm assuming) plans soon!

@wooloosus6866 8 жыл бұрын

Unfortunately, this was before CC Astronomy, so that was probably the secret plan he was talking about :( But here's to hoping there's still a death star in the making!
