Starquakes Could Be Behind 3 Cosmic Mysteries

The video explores seismic activity on Earth and other celestial bodies, including stars. It delves into star quakes, particularly in neutron stars, and their potential link to fast radio bursts (FRBs) and pulsar glitches. The Blasco effect in variable stars is also discussed, highlighting the role of seismic waves in these phenomena. The video emphasizes the importance of studying star quakes to understand the internal workings of celestial objects.

What do seismic waves help us understand about celestial bodies?

• Their surface temperature

• Their internal structure

• Their orbital path

• Their magnetic field

What is the 'nuclear pasta' in neutron stars known for?

• Being the hottest material

• Being the most elastic material

• Being the most magnetic material

• Being the most radioactive material

What phenomenon might star quakes on neutron stars help explain?

• Fast radio bursts

• Black holes

• Gamma-ray bursts

• Solar flares

What unexpected event occurs in pulsars that might be linked to star quakes?

• A brief increase in rotation speed

• A change in color

• A sudden stop in rotation

• A decrease in size

How do star quakes potentially affect the rotation of pulsars?

• By increasing their mass

• By moving their center of mass closer to the rotation axis

• By changing their magnetic field

• By altering their temperature

What is the Blasco effect observed in RR Lyrae stars?

• A change in their orbital path

• A variation in their brightness peaks over time

• A shift in their color spectrum

• A fluctuation in their temperature

What might be responsible for the Blasco effect in RR Lyrae stars?

• Cosmic rays

• Gravitational waves

• Magnetic fields

• Seismic waves
