WorldCon 2016: Two suns in the sky

Disclaimer: I am not perfect and neither are my notes. If you notice anything that requires clarification or correction, please email me at melanie (dot) marttila (at) gmail (dot) com and I will fix things post-hasty.

Panellists: Eva Elasigue, Courtney Schafer, [Mel’s note: Joe Haldeman was unable to attend.]

Joined in progress …

CS: Kepler discovers exoplanets by observing the subtle signs of a planet passing in front of its star. It’s focused on a small area and it’s only covered 3% of that space in detail so far. The number of exoplanets discovered is large, but only a fraction of circum-binary systems have planets that might be habitable. The planets discovered in those systems are massive, though. It’s exciting that so many planets have been discovered.

EE: One of Larry Niven’s conjectures is that a planet in a binary system would have an off-center core.

CS: It’s possible that a planet in a binary system could have a figure eight orbit. It could also be more easily ejected from the system. Since circum-binary systems are fairly common, there might be a large number of rogue planets out there. To discover the composition of a planet, you need to use spectroscopy.

Q: Is there publicly accessible software for fact-checking the plausibility of an invented system?

A: There are solar system simulators.

CS: You can also check with your local amateur astronomy club.

Q: Is Alpha Centauri A, Rigil Kentaurus, a binary star?

CS: That’s the current understanding. One thing to keep in mind is the force that would be exerted on planets in these systems. If we look at the moons of Jupiter, they need to have their own magnetospheres to maintain an atmosphere. Otherwise, Jupiter strips it away.

EE: You should check out Galaxy Zoo. It’s a citizen science initiative.

[At this point, the ideas starting coming fast and furious. To be honest, I’m not sure who said what.]

The most favorable binary systems for planets are those in which both stars are around 80% of the sun’s size. They’re also fairly close to each other. The minimum stable radius for a planet in a binary system is 2-4 times larger than [… sorry didn’t catch this. I think it’s Jupiter. Wikipedia indicates this would be correct. If the planet is a gas giant, it may not support life, but its moons might. Smaller stars would accommodate smaller planets, but the planets may not be habitable, depending on their orbits and the relative light and heat they receive from their suns.]

They probably didn’t form in their current orbit. There’s an instability in binary systems which could result in the planet spiralling into one of the stars, or being flung out of the system. Planets in binary systems would move around unless they could find a stable orbit.

There are also mismatched binary systems. A blue giant with a red dwarf, for example, or a sun-type star with a black hole.

And that was time.

For more information: If you Google the term circum-binary systems, you will find a lot. Navigate to dependable sources, like NASA, or Space.com (unlike yours truly). Or head for fun but dependable sites like Phil Plait’s Bad Astronomy column, currently hosted by Blastr.

Next week: we’re terraforming terra 🙂

Until next I blog, be well, be kind, and stay strong.

Thoughty Thursday: Things that made me go hmmmm on the interwebz, Sept 28-Oct 4, 2014

Some facts and some fun. Just what you were waiting for!

Valerie Strauss of The Washington Post asks the question, is homework an unnecessary evil? I can tell you, I rarely did mine, even in high school. If you’re heading for university, all you really need to learn is independent study skills and effective note taking (IMHO).

Fashion through the ages, from Viral Spell.

Looking for some information on exoplanets? This great series of graphics (artists’ renderings) from Space.com includes information (off to the right) with a read more link. Could one of these planets be the setting of your next science fiction story?

Fabulous information from Popular Mechanics on how we might actually build a space colony.

National Geographic features pictures of Palmyra Atoll. It’s the world’s largest marine reserve.

More of the National Geographic’s 2014 Photo Contest featured in The Atlantic’s In focus column.

This guy can really toot his own horn 😉 The CBC reports on a Laurier student who covers Outkast’s Hey ya! on his French horn using his Mac to loop tracks.

John Scalzi share this Mary Lambert video last week and I fell in love. Seriously. I think this might be my new anthem 🙂

Now this was useful 🙂 45 essential dog care hacks, from Lifehack.

Discovery shares pictures of kissable animals. Some of these choices might be questionable.

We’ve seen dog shaming pictures a-plenty. Well, here’s some cat shaming pictures from Pet Stuff Web that beg the question, are these cats really shamed?

Itty bitty piggies!

Thanks for coming along for the ride.

See you Saturday with more WWC2014!
