Calibrating Nebular Diagnostics of T and Abundance
We obtained nebular spectroscopy of LMC H II regions having classified stellar populations, thereby strongly constraining the ionization input parameters. Using photoionization models, we then evaluate the performance of nebular diagnostics of T? and abundance. We introduce [Ne III]/Hβ as a nebular diagnostic of the ionizing stellar T?. In contrast to the widely-used η ′ parameter, [Ne III]/Hβ ...

The errors inherent to the use of the standard " ionization correction factor " (" i CF ") method of calculating nebular conditions and relative and Ar in emission line nebulae have been investigated under conditions typical for planetary nebulae. The photoionization code Cloudy was used to construct a series of model nebulae with properties spanning the range typical of PNe. Its radial " profi...
متن کاملM 101 Revisited . II . Electron Temperatures and Implications for the Nebular Abundance Scale
We use high signal/noise spectra of 20 H II regions in the giant spiral galaxy M101 to derive electron temperatures for the H II regions and robust metal abundances over radii R = 0.19–1.25 R0 (6–41 kpc). We compare the consistency of electron temperatures measured from the [O III]λ4363, [N II]λ5755, [S III]λ6312, and [O II]λ7325 auroral lines. Temperatures from [O III], [S III], and [N II] are...
متن کاملChondrules and Nebular Shocks
Beneath the fusion-encrusted surfaces of the most primitive stony meteorites lies not homogeneous rock, but a profusion of millimeter-sized igneous spheres. These chondrules, and their centimeter-sized counterparts, the calcium-aluminum-rich inclusions, comprise more than half of the volume fraction of chondritic meteorites. They are the oldest creations of the solar system. Their chemical comp...
متن کاملModelling of Nebular Line Profiles
RESUMEN El resumen será traducido al español por los editores. We present a tool, VELNEB 3D, which can be applied to the results of 3D photoionization codes to generate emission line profiles, position-velocity maps and 3D maps in any emission line by assuming an arbitrary velocity field. We give a few examples, based on our pseudo-3D photoionization code NEBU 3D (Morisset, Stasi´nska & Peña 20...
