NGC 346 in The Small Magellanic Cloud. IV. Triggered Star Formation in the HII Region N66
Dimitrios A. Gouliermis, You-Hua Chu, Thomas Henning +4
Stellar feedback, expanding HII regions, wind-blown bubbles, and supernovae are thought to be important triggering mechanisms of star formation. Stellar associations, being hosts o…
CHANDRA ACIS Spectroscopy of N157B -- A Young Composite Supernova Remnant in a Superbubble
Yang Chen, Q. Daniel Wang, Eric V. Gotthelf +3
We present Chandra ACIS observations of N157B, a young supernova remnant located in the 30 Doradus star-formation region of the LMC. This remnant contains the most energetic pulsar…
X-ray and UV Views of Hot Gas in Planetary Nebulae
You-Hua Chu, Martin A. Guerrero, Robert A. Gruendl
The interior of a planetary nebula (PN) is expected to be filled with shocked fast wind from the central star. This hot gas plays the most important role in the dynamical evolution…
Variable H-alpha Line Emission from the Central Star of the Helix Nebula
Robert A. Gruendl, You-Hua Chu, Ian J. O'Dwyer +1
The central star of the Helix Nebula is a hot white dwarf with unexpected hard X-ray emission. With an effective temperature of ~100,000 K, the star is a powerful source of H-ioniz…
ROSAT observations of X-ray emission from planetary nebulae
Martin A. Guerrero, You-Hua Chu, Robert A. Gruendl
We have searched the entire ROSAT archive for useful observations to study X-ray emission from Galactic planetary nebulae (PNs). The search yields a sample of 63 PNs, which we call…
