Hubble study finds dwarf galaxies lose most of their oxygen
Supernova-driven winds appear more effective than models predict.
Status: source-checked.
Researchers using NASA’s Hubble Space Telescope studied 37 nearby dwarf galaxies and found much of the oxygen they expected is missing, NASA said Nov. 2.
Galactic winds unleashed by supernovae appear more effective at removing oxygen from low-mass galaxies than current models predict, according to the study in The Astrophysical Journal.
