A white dwarf star is the compact, dense remnant of a once-thriving solar system. Long after the original star has died and turned into a white dwarf, it can still interact with its solar system. We can even see white dwarfs eating up the rocky debris that once made up their solar system, and apparently making sense of all of this requires a detailed understanding of how convection works in these dead stellar remnants.

How did the planets form? What was going on in the first few brief million years of our solar system? And how did it impact what we see in our solar system today? Dr. Merel van 't Hoff takes us on a journey through astrochemistry to understand the planetary wombs that house solar systems in their prenatal years.

What kinds of things do neutron stars do? They can smash into each other, producing bright flashes of radiation and strong ripples in spacetime that can be detected across the universe! Or, a neutron star can just be sitting there, and its magnetic field might suddenly shift and produce a dramatic burst of radio waves! But mainly, neutron stars are super-dense and super-complicated, giving us a probe of fundamental physics in its most extreme limits. Dr. Wen-Fai Fong tells us all about how we can learn more!
