Spitzer IRS Spectroscopy of Intermediate Polars: Constraints on Mid-Infrared Cyclotron Emission
Thomas E. Harrison, Ryan K. Campbell, Steve B. Howell +2
We present Spitzer Infrared Spectrograph (IRS) observations of eleven intermediate polars (IPs). Spectra covering the wavelength range from 5.2 to 14 m are presented for all ele…
The Nature of the Secondary Star in the Black Hole X-Ray Transient V616 Mon (=A0620-00)
Thomas E. Harrison, Steve B. Howell, Paula Szkody +1
We have used NIRSPEC on Keck II to obtain -band spectroscopy of the low mass X-ray binary V616 Mon (= A062000). V616 Mon is the proto-typical soft x-ray transient containing…
GALEX and Optical Light Curves of EF Eridanus During a Low State: the Puzzling Source of UV Light
Paula Szkody, Thomas E. Harrison, Richard M. Plotkin +3
Low state optical photometry of EF Eri during an extended low accretion state combined with GALEX near and far UV time-resolved photometry reveals a source of UV flux that is much…
First Spitzer Space Telescope Observations of Magnetic Cataclysmic Variables: Evidence for Excess Emission at 3--8 microns
Steve B. Howell, Carolyn Brinkworth, D. W. Hoard +7
We present the first observations of magnetic cataclysmic variables with the Spitzer Space Telescope. We used the Infrared Array Camera to obtain photometry of the polars EF Eri, G…
The FSVS Cluster Catalogue: Galaxy Clusters and Groups in the Faint Sky Variability Survey
Ilona K. Soechting, Mark E. Huber, Roger G. Clowes +1
We describe a large sample of 598 galaxy clusters and rich groups discovered in the data of the Faint Sky Variability Survey. The clusters have been identified using a fully automa…
Color and Variability Characteristics of Point Sources in the Faint Sky Variability Survey
M. E. Huber, M. E. Everett, S. B. Howell
We present an analysis of the color and variability characteristics for point sources in the Faint Sky Variability Survey (FSVS). The FSVS cataloged ~23 square degrees in BVI filte…
