In today’s paper, the authors study how the periods of two black hole x-ray binaries are changing. They find that the periods are decaying faster than expected based on standard theoretical arguments.
With some assistance from gravity, it is possible with currently-available technologies to bring small asteroids into orbit next to Earth to be studied and mined.
This article considers the fate of planets that orbit stars that will become white dwarfs. Can they survive? Could they be habitable?
A phenomenological series of simulations of dwarf galaxies placed on different orbits around a Milky Way-like galaxy, in order to learn about the properties (and observability) of tidal tails in dwarf galaxies around our Milky Way.
Remember that tidal disruption event we talked about earlier this year, where a star got just a little too close to a quiescent black hole? Well, here’s our chance to witness something similar, happening in the center of our very own galaxy!
