What happens to planets when their host star dies? Today’s authors explore how HR 8799 could become a metal-polluted white dwarf in an unusual planetary system.
When the rotation of a star is misaligned from the orbits of its planets, astronomers often attribute the misalignment to planetary dynamics. In the case of K2-290 A, today’s authors instead attribute its misalignment to its stellar companion.
With a new generation of space and ground based telescopes on the horizon, we will soon have the tools to efficiently begin looking for life’s signatures in exoplanet atmospheres. Where should we look first to maximize our chances?
Can interactions between magma and a planetary atmosphere create a water dominated super-Earth?
Today’s authors found a unique occupant of the “brown dwarf desert,” on an extremely close orbit around its M dwarf host.
How can we safely convene for conferences during the pandemic? A tool called Gather may be the solution.
