Co-spatial UV-optical HST/STIS Spectra of Six Planetary Nebulae: Nebular and Stellar Properties

Timothy R. Miller, Richard B. C. Henry, Bruce Balick +4

This paper represents the conclusion of a project that had two main goals: (1) to investigate to what extent planetary nebulae (PNe) are chemically homogeneous; and (2) to provide…

Analysis of Co-spatial UV-optical STIS Spectra of Planetary Nebula NGC 3242

Timothy R. Miller, Richard B. C. Henry, Bruce Balick +4

This project sought to consider two important aspects of the planetary nebula NGC 3242 using new long-slit HST/STIS spectra. First, we investigated whether this object is chemicall…

Spitzer observations of extragalactic H II regions - III. NGC 6822 and the hot star, H II region connection

Robert H. Rubin, Janet P. Simpson, Sean W. J. Colgan +5

Using the short-high module of the Infrared Spectrograph on the Spitzer Space Telescope, we have measured the [S IV] 10.51, [Ne II] 12.81, [Ne III] 15.56, and [S III] 18.71-micron…

Co-spatial Long-slit UV/Optical Spectra of Ten Galactic Planetary Nebulae with HST/STIS II. Nebular Models, Central Star Properties and He+CNO Synthesis

R. B. C. Henry, B. Balick, R. J. Dufour +5

The goal of the present study is twofold. First, we employ new HST/STIS spectra and photoionization modeling techniques to determine the progenitor masses of eight planetary nebula…

Co-spatial Long-slit UV/Optical Spectra of Ten Galactic Planetary Nebulae with HST/STIS I. Description of the Observations, Global Emission-line Measurements, and CNO Abundances

Reginald J. Dufour, Karen B. Kwitter, Richard A. Shaw +3

We present observations and initial analysis from an HST/STIS program to obtain the first co-spatial, UV-optical spectra of ten Galactic planetary nebulae (PNe). Our primary object…

Spitzer Observations of M33 and the Hot Star, H II Region Connection

Robert H. Rubin, Janet P. Simpson, Sean W. J. Colgan +7

We have observed emission lines of [S IV] 10.51, H(7-6) 12.37, [Ne II] 12.81, [Ne III] 15.56, and [S III] 18.71 um in a number of extragalactic H II regions with the Spitzer Space…
