Scattering polarization due to light source anisotropy
R Ignace, M Al-Malki, J Simmons +3
We consider the polarization arising from scattering in an envelope illuminated by a central anisotropic source. Spherical harmonics are used to describe both the light source anis…
Polarization from the Structured Envelopes of Cool Evolved Stars
R Ignace, G D Henson, J Carson
We present preliminary calculations of electron scattering polarizations from models of structured cool star envelopes. We note that net polarizations from unresolved sources can r…
The Impact of Transiting Planet Science on the Next Generation of Direct-Imaging Planet Searches
Joseph C. Carson
Within the next five years, a number of direct-imaging planet search instruments, like the VLT SPHERE instrument, will be coming online. To successfully carry out their programs, t…
Frame Combination Techniques for Ultra High-Contrast Imaging
Joseph C. Carson, Markus Feldt, Silvano Desidera +4
We summarize here an experimental frame combination pipeline we developed for ultra high-contrast imaging with systems like the upcoming VLT SPHERE instrument. The pipeline combine…
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…
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),…
