While transits can reveal much about a planet’s diameter, they cannot place accurate constraints on a planet’s mass. For this, the Radial Velocity method (as noted earlier) is the most reliable, where astronomers look for signs of “wobble” in a star’s orbit to the measure the gravita...

Scientists rely on ingenious methods like the transit method, where they observe a slight dip in the star's brightness as a planet passes in front of it, and the radial velocity method, where they detect the subtle wobble of a star caused by the gravitational pull of ...
In summary, my professor said that the moment of inertia of a system is equal to the sum of the moment of inertia of each of its masses. However, I don't see why we can use R here rather than the distance from the center of the pulley to the mass. Isn't the moment of inertia...
where is a time-dependent scalar field (representing pressure), and is a time-dependent vector field (representing fluid velocity). Here is the Levi-Civita connection associated to . One can recover from (up to constants), so I will abuse notation and refer to the solution to this system ...

the solution of a differential equation is expressed as a constant term and an adjustable term with unknown parameters, the best parameter values are determined via a neural network. However, their method only works for problems with regular borders. Lagaris et al [90] extends the method to pr...
