StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

Why not?

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

Because a coronal mass ejection or sunspots that rotate around, you know,

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

They do not give the same signal in the periodicity of the quakes.

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

I'm quaking my microphone right now.

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

So, you know, a coronal mass ejection is an abrupt event.

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

It's more like an earthquake, you could say.

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

It happens and it disappears, right?

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

But it doesn't disturb us finding the five-minute oscillations of the sun, which are always there, yeah?

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

They get disturbed.

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

abruptly but then they continue and they continue and they continue all the time so for us you know we can we can unravel the signal of star spots of mass ejections even for stars other than the sun from the always smooth periodic oscillation so how about the dangers that they might pose if you do have a coronal mass ejection that happens to head towards us

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

Yeah, so the Earth is protected by a magnetic field that protects us from all these high energetic particles falling in on our planet and other stars are too far away.

So, I mean, it's only a matter of the solar quakes.

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

They are not dangerous for us.

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

The coronal mass ejections, they disturb our electronics every once in a while, right?

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

But, you know, that's not a periodic oscillation that I would call solar quakes.

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

A starquake would not rip apart a star because it's really a smooth, nice periodic variability.

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

You know, the biggest starquakes in terms of expansion and contraction, let's say, can make the star become bigger and smaller by about 10% in its radius, let's say, but not make it explode.

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

That's another phenomenon.

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

Well, star quakes happen all the time.

StarTalk Radio
Cosmic Queries โ€“ Starquakes with Conny Aerts

I keep repeating that.
