Globular clusters have puzzled astronomers with the presence of different distinct populations of stars; is dark matter a possible solution to this problem?
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.
Using new observations from the UVCANDELS survey, a possible link between recent star formation, merger frequency, and the size-mass evolution of massive, quiescent galaxies is investigated.
We report on Day 5 of the virtual winter AAS meeting.
We report on Day 4 of the virtual winter AAS meeting.
Today’s paper looks at GD 424, a very hungry white dwarf that is accreting planets!
