What can we learn from radial velocity?
What can we learn from radial velocity? The radial velocity technique is able to detect planets around low-mass stars, such as M-type (red dwarf) stars. This is due to the fact that low mass stars are more affected by the gravitational tug of planets and because such stars generally rotate more slowly (leading to more […]

Why do O and B type stars have weaker hydrogen absorption lines?

This results in weaker absorption lines, because very few hydrogen atoms are participating. You cannot measure the temperature of the star based […]
Is there gravity underwater?
Is there gravity underwater? There is plenty of gravity underwater. That gravity is just offset by buoyancy, which is caused by the pressure in the column underneath a submerged object being greater than the pressure in the column above that object, resulting in net upward force on the object that mostly (but not completely) balances […]
