SDSS-V LVM: Resolving Physical Conditions in the Trifid Nebula
Natascha Sattler, J. Eduardo Méndez-Delgado, Kathryn Kreckel +18
The chemical abundance of the interstellar medium sets the initial conditions for star formation and provides a probe of chemical galaxy evolution models. However, unresolved inhom…
Can Wolf-Rayet stars be the missing ingredient to explain high-z He II ionizing radiation?
G. González-TorÃ, A. A. C. Sander, E. Egorova +7
Classical Wolf-Rayet (WR) stars are hot, massive stars with depleted hydrogen. At low metallicities (Z), WN3-type WR stars have relatively thin winds and are major sources of ioniz…
SDSS-V LVM: Detectability of Wolf-Rayet stars and their He II ionizing flux in low-metallicity environments I. The weak-lined, early-type WN3 stars in the SMC
G. González-TorÃ, A. A. C. Sander, E. Egorova +18
The Small Magellanic Cloud (SMC) is the nearest low-metallicity dwarf galaxy. Its proximity and low reddening has enabled us to detect its Wolf-Rayet (WR) star population with 12 k…
Extremely iron-poor O-type stars in the Magellanic Bridge
E. C. Schösser, V. Ramachandran, A. A. C. Sander +7
To study stars analogous to those in the early Universe with redshift z > 3, we need to probe environments with low metallicities. Until recently, massive O-type stars with metalli…
Gas-phase Fe/O and Fe/N abundances in Star-Forming Regions. Relations between nucleosynthesis, metallicity and dust
J. E. Méndez-Delgado, K. Kreckel, C. Esteban +10
In stars, metallicity is usually traced using Fe, while in nebulae, O serves as the preferred proxy. Both elements have different nucleosynthetic origins and are not directly compa…
