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…
Hard X-ray and Infrared Emission from Apparently Single White Dwarfs
Y. -H. Chu, R. A. Gruendl, M. A. Guerrero +1
The photospheric emission of a white dwarf (WD) is not expected to be detectable in hard X-rays or the mid-IR. Hard X-ray (~1 keV) emission associated with a WD is usually attribut…
