Kepler and the Long Period Variables
Erich Hartig, Jennifer Cash, Kenneth Hinkle +3
High precision Kepler photometry is used to explore the details of AGB light curves. Since AGB variability has a typical time scale on order of a year we discuss at length the remo…
Deviations from He I Case B Recombination Theory and Extinction Corrections in the Orion Nebula
K. P. M. Blagrave, P. G. Martin, R. H. Rubin +4
We are engaged in a comprehensive program to find reliable elemental abundances in and to probe the physical structure of the Orion Nebula, the brightest and best-resolved H II reg…
The Starburst-Interstellar Medium Interaction of NGC 1569 I. Location and Nature of He II Sources Using Hubble Space Telescope WFPC2 Imagery
Brent A. Buckalew, Reginald J. Dufour, Patrick L. Shopbell +1
We present the detection of He II sources in the Im galaxy NGC 1569 from HST WFPC2 imagery. Out of the fifteen detections, seven were Wolf-Rayet stars, five were stellar clusters w…
Physical Conditions in Low Ionization Regions of the Orion Nebula
J. A. Baldwin, A. Crotts, R. J. Dufour +12
We reexamine the spectroscopic underpinnings of recent suggestions that [O I] and [Fe II] lines from the Orion H II region are produced in gas where the iron-carrying grains have b…
