Protostars, Dust Globules, and a Herbig-Haro Object in the LMC Superbubble N51D
Y. -H. Chu, R. A. Gruendl, C. -H. R. Chen +9
Using Spitzer Space Telescope and Hubble Space Telescope observations of the superbubble N51D, we have identified three young stellar objects (YSOs) in dust globules, and made the…
Energy Crisis in the Superbubble DEM L 192 (N 51D)
R. L. Cooper, M. A. Guerrero, Y. -H. Chu +2
Superbubbles surrounding OB associations provide ideal laboratories to study the stellar energy feedback problem because the stellar energy input can be estimated from the observed…
Diffuse X-Ray Emission from the Quiescent Superbubble M17, the Omega Nebula
B. C. Dunne, Y. -H. Chu, C. -H. R. Chen +5
The emission nebula M17 contains a young ~1 Myr-old open cluster; the winds from the OB stars of this cluster have blown a superbubble around the cluster. ROSAT observations of M17…
The Wind of the B[e] Supergiant Hen S22 Viewed through a Reflection Nebula in DEM L 106
Y. -H. Chu, C. -H. R. Chen, C. Danforth +5
Narrow-band HST WFPC2 images reveal a bow-shock-like halo around the HII region N30B toward the B[e] supergiant Hen S22 located within the larger DEM L 106 nebula in the Large Mage…
A Search for Jovian Planets around Hot White Dwarfs
Y. -H. Chu, B. C. Dunne, R. A. Gruendl +1
Current searches for extrasolar planets have concentrated on observing the reflex Doppler shift of solar-type stars. Little is known, however, about planetary systems around non-so…
A Morphological Diagnostic for Dynamical Evolution of Wolf-Rayet Bubbles
Robert A. Gruendl, You-Hua Chu, Bryan C. Dunne +1
We have observed H-alpha and [OIII] emission from eight of the most well defined Wolf-Rayet ring nebulae in the Galaxy. We find that in many cases the outermost edge of the [OIII]…
What Produced the Ultraluminous Supernova Remnant in NGC 6946?
Bryan C. Dunne, Robert A. Gruendl, You-Hua Chu
The ultraluminous supernova remnant (SNR) in NGC 6946 is the brightest known SNR in X-rays, ~1000 times brighter than Cas A. To probe the nature of this remnant and its progenitor,…
