The Head-on Collision of a Neutron Star with a White Dwarf
We have computed the physical processes involved in a head-on collision between a neutron star (NS) and a white dwarf (WD). The outcomes of such collisions vary depending on the mass and type of the W...

Follow-up Observations of Candidate White Dwarf Planets with MIRI
We report on second-epoch imaging of two candidate planet-hosting white dwarfs stars, WD2105-82 and WD1202-232. Both stars showed evidence of resolved, planet-mass candidate companions in observations...
