Spying into the lives of the stars
... Explaint that we know that, like humans, stars are born, grow up, and die. It’s just that stars take longer to do these things: millions and billions of years. You can’t really just take a single star and follow it from birth to death, so today, we will use some of the tools that astronomers use to ...

Comparing Earth, Sun and Jupiter
... Gas and dust in the disk (total mass ~0.01 MSun) orbit the protostar in nearly circular orbits However, the gas is also partially supported by pressure, so it orbits more slowly. Thus, the dust grains feel a headwind of ~10 m/s due to the gas. The smallest dust grains then orbit with the gas ...
