Observing Strategies for the NICI Campaign to Directly Image Extrasolar Planets
Beth Biller, Etienne Artigau, Zahed Wahhaj +7
We discuss observing strategy for the Near Infrared Coronagraphic Imager (NICI) on the 8-m Gemini South telescope. NICI combines a number of techniques to attenuate starlight and s…
Performance of the Near-infrared coronagraphic imager on Gemini-South
Mark Chun, Doug Toomey, Zahed Wahhaj +8
We present the coronagraphic and adaptive optics performance of the Gemini-South Near-Infrared Coronagraphic Imager (NICI). NICI includes a dual-channel imager for simultaneous spe…
NICI: combining coronagraphy, ADI, and SDI
Etienne Artigau, Beth A. Biller, Zahed Wahhaj +9
The Near-Infrared Coronagraphic Imager (NICI) is a high-contrast AO imager at the Gemini South telescope. The camera includes a coronagraphic mask and dual channel imaging for Spec…
A First Estimate Of The X-Ray Binary Frequency As A Function Of Star Cluster Mass In A Single Galactic System
D. M. Clark, S. S. Eikenberry, B. R. Brandl +7
We use the previously-identified 15 infrared star-cluster counterparts to X-ray point sources in the interacting galaxies NGC 4038/4039 (the Antennae) to study the relationship bet…
The Neon Abundance in the Ejecta of QU Vul From Late-Epoch IR Spectra
Robert D. Gehrz, Charles E. Woodward, L. Andrew Helton +10
We present ground-based SpectroCam-10 mid-infrared, MMT optical, and Spitzer Space Telescope IRS mid-infrared spectra taken 7.62, 18.75, and 19.38 years respectively after the outb…
Infrared Counterparts to Chandra X-Ray Sources in the Antennae
D. M. Clark, S. S. Eikenberry, B. R. Brandl +7
We use deep J and Ks images of the Antennae (NGC 4038/9) obtained with WIRC on the Palomar 200-inch telescope, together with the Chandra X-ray source list of Zezas et al. (2002a),…
