Optical Spectroscopy of the Large Kuiper Belt Objects 136472 (2005 FY9) and 136108 (2003 EL61)
S. C. Tegler, W. Grundy, W. Romanishin +3
We present high signal precision optical reflectance spectra of the large Kuiper belt objects 2005 FY9 and 2003 EL61. The spectrum of 2005 FY9 exhibits strong CH4-ice bands. A comp…
Resonance varieties over fields of positive characteristic
Michael Falk
This is a revision and update of the part of the preprint math.CO/0405210 concerning field coefficients, line complexes, and the Hessian arrangement. The material from that paper c…
The Spitzer c2d Survey of Nearby Dense Cores: IV. Revealing the Embedded Cluster in B59
Timothy Y. Brooke, Tracy L. Huard, Tyler L. Bourke +22
Infrared images of the dark cloud core B59 were obtained with the Spitzer Space Telescope as part of the "Cores to Disks" Legacy Science project. Photometry from 3.6-70 microns ind…
A New Brown Dwarf Desert? A Scarcity of Wide Ultracool Binaries
Peter R. Allen, David W. Koerner, Michael W. McElwain +2
We present the results of a deep-imaging search for wide companions to low-mass stars and brown dwarfs using NSFCam on IRTF. We searched a sample of 132 M7-L8 dwarfs to magnitude l…
The Spitzer c2d Survey of Nearby Dense Cores: I: First Direct Detection of the Embedded Source in IRAM 04191+1522
M. M. Dunham, N. J. Evans, T. L. Bourke +9
We report the first detections of the Class 0 protostellar source IRAM 04191+1522 at wavelengths shortward of 60 microns with the Spitzer Space Telescope. We see extended emission…
Multinets, resonance varieties, and pencils of plane curves
Michael Falk, Sergey Yuzvinsky
We show that a line arrangement in the complex projective plane supports a nontrivial resonance variety if and only if it is the underlying arrangement of a "multinet," a multi-arr…
