I am very excited about this paper by Yuan-Sen Ting and myself on arxiv tonight! We show that local dwarf galaxies can retain signatures of early bursty star formation in their chemical patterns, and show that the Sculptor dSph could have such a signature. arxiv.org/abs/2408.06807 🔭

Quantifying Bursty Star Formation in Dwarf Galaxies

Dwarf galaxy star formation histories are theoretically expected to be bursty, potentially leaving distinct imprints on their chemical evolution. We propose that episodic starbursts with quiescent...

YST and I realized that you can get really large metallicity gaps due to Type Ia SNe enrichment during long quiescent periods in a galaxy’s star formation history. The SNe keep going off even though you stop forming stars, which can show up in chemical evolution.
