Kinematical analysis of PNe with high ADF: Hf 2-2 and M 1-42
Lesly Castañeda-Carlos, Michael G. Richer, Silvia Torres-Peimbert +2
We use deep Echelle spectroscopy of the planetary nebulae Hf 2-2 and M1-42 to study the characteristics of the plasma that gives rise to their high abundance discrepancy factors (7…
NGC 6153: Reality is complicated
Michael G. Richer, Anabel Arrieta, Lorena Arias +4
We study the kinematics of emission lines that arise from many physical processes in NGC 6153 based upon deep, spatially-resolved, high resolution spectra acquired with the UVES sp…
Creating and using large grids of pre-calculated model atmospheres for rapid analysis of stellar spectra
Janos Zsargó, Celia Rosa Fierro-Santillán, Jaime Klapp +4
We present a database of 45,000 atmospheric models (which will become 80,000 models by the end of the project) with stellar masses between 9 and 120 M, covering the regio…
Creating and using large grids of precalculated model atmospheres for a rapid analysis of stellar spectra
J. Zsargo, C. R. Fierro-Santillan, J. Klapp +6
We present a database of 43,340 atmospheric models (80,000 models at the conclusion of the project) for stars with stellar masses between 9 and 120 , cover…
FIT{\it spec}: a new algorithm for the automated fit of synthetic stellar spectra for OB stars
Celia R. Fierro-Santillán, Janos Zsargó, Jaime Klapp +4
In this paper we describe the FIT\textit{spec} code, a data mining tool for the automatic fitting of synthetic stellar spectra. The program uses a database of 27\,000 {\sc cmfgen}…
The Discrepant Kinematics of ORLs and CELs in NGC 7009 as a Function of Ionization Structure
Michael G. Richer, Leonid Georgiev, Anabel Arrieta +1
We present spatially- and velocity-resolved echelle spectroscopy for NGC 7009 obtained with the UVES spectrograph at the European Southern Observatory's Very Large Telescope. Our o…
