LISTENING FOR THE HUM OF NEUTRON STARS IN THE CENTER
... allows us to set an upper limit on the gravitational wave strength in the searched frequency and spindown band and for the searched sky location. That means we can define a maximum strength that signals from the direction of the Galactic Center can have. These values are determined with 90% confiden ...

Chapter Exercise
... Imagine that a spacecraft is initially in the orbit X. It has to accelerate (e.g. by firing a rocket) at the leftmost point in order to enter orbit Y. In other words, the spacecraft has gained KE during the orbital transition. In contrast, a spacecraft initially in orbit Z has to decelerate at the r ...
