Suzaku and XMM-Newton Observations of Diffuse X-ray Emission from the Eastern Tip Region of the Carina Nebula

Yuichiro Ezoe, Kenji Hamaguchi, Robert A. Gruendl +3

The eastern tip region of the Carina Nebula was observed with the Suzaku XIS for 77 ks to conduct a high-precision spectral study of extended X-ray emission. XMM-Newton EPIC data o…

Were All Massive Stars Born in OB Associations and Clusters?

You-Hua Chu, Robert A. Gruendl

It has been commonly conjectured that all massive >10 Msun stars are born in OB associations or clusters. Many O and B stars in the Galaxy or the Magellanic Clouds appear to exist…

Structure of Supergiant Shells in the Large Magellanic Cloud

Laura G. Book, You-Hua Chu, Robert A. Gruendl

Nine supergiant shells (SGSs) have been identified in the Large Magellanic Cloud (LMC) based on H-alpha images, and twenty-three SGSs have been reported based on HI 21-cm line obse…

Large-Scale Gravitational Instability and Star Formation in the Large Magellanic Cloud

Chao-Chin Yang, Robert A. Gruendl, You-Hua Chu +2

Large-scale star formation in disk galaxies is hypothesized to be driven by global gravitational instability. The observed gas surface density is commonly used to compute the stren…

A Debris Disk around the Central Star of the Helix Nebula?

Kate Y. L. Su, Y. -H. Chu, G. H. Rieke +6

Excess emission from a point-like source coincident with the central star of the Helix Nebula is detected with Spitzer at 8, 24, and 70 um. At 24 um, the central source is superpos…
