An Atlas of Far-ultraviolet Spectra of the Zeta Aurigae Binary 31 Cygni with Line Identifications
Bennett, Philip D.; Hagen Bauer, Wendy
The ζ Aurigae system 31 Cygni (K4 Ib + B4 V) was observed by the FUSE satellite during total eclipse and at three phases during chromospheric eclipse. We present the coadded, calibrated spectra and atlases with line identifications. During total eclipse, emission from high ionization states (e.g., Fe III and Cr III) shows asymmetric profiles redsh…
The ACS Survey of Globular Clusters. XIII. Photometric Calibration in Comparison with Stetson Standards
Anderson, Jay; Majewski, Steven R.; Sarajedini, Ata +11 more
In this study we compare the photometric data of 34 Milky Way globular clusters, observed within the Advanced Camera for Surveys (ACS) Treasury Program (PI: A. Sarajedini) with the corresponding ground-based data, provided by the Photometric Standard Field Catalogs of Stetson. We focus on the transformation between the Hubble Space Telescope/ACS F…
A Deep Chandra Observation of the Giant H II Region N11. I. X-Ray Sources in the Field
Nazé, Yaël; Chu, You-Hua; Wang, Q. Daniel +2 more
A very sensitive X-ray investigation of the giant H II region N11 in the Large Megallanic Cloud was performed using the Chandra X-ray Observatory. The 300 ks observation reveals X-ray sources with luminosities down to 1032 erg s-1, increasing the number of known point sources in the field by more than a factor of five. Among …
