Periodicities In The X-Ray Intensity Variations of TV Columbae: An Intermediate Polar
V. R. Rana, K. P. Singh, E. M. Schlegel +1
We present results from a temporal analysis of the longest and the most sensitive X-ray observations of TV Columbae--an intermediate polar. The observations were carried out with t…
Chandra ACIS and Newton EPIC Observations of the X-ray Luminous SN1978K in NGC 1313
Eric M. Schlegel, Albert Kong, Philip Kaaret +2
We describe an observation of the X-ray luminous SN1978K in NGC 1313 using the ACIS detector on Chandra and an archival Newton EPIC observation. The models that provided good fits…
Chandra Multi-wavelength Project (ChaMP). II. First Results of X-ray Source Properties
D. -W. Kim, B. J. Wilkes, P. J. Green +15
We present the first results of ChaMP X-ray source properties obtained from the initial sample of 62 observations. The data have been uniformly reduced and analyzed with techniques…
A Chandra Observation of the Diffuse Emission in the Face-on Spiral NGC 6946
E. M. Schlegel, S. S. Holt, R. Petre
This paper describes the {\it Chandra} observation of the diffuse emission in the face-on spiral NGC 6946. Overlaid on optical and H images, the diffuse emission follows the spi…
Hard X-ray Observations of Magnetic Cataclysmic Variables
K. P. Singh, V. R. Rana, K. Mukerjee +2
Hard X-ray light curves and spectral parameters from our analysis of X-ray data of five AM Her type systems - V2301 Oph, V1432 Aql, EP Draconis, GG Leonis, V834 Cen, and one interm…
The Chandra Observation of the IP TX Col
Eric M. Schlegel, Anandi Salinas
We present a preliminary look at the serendipitous observation of the intermediate polar TX Col by Chandra. The 52 ksec observation is uninterrupted, providing an opportunity to di…
Chandra Observations of Associates of Car: I. Luminosities
Nancy Remage Evans, Frederick D. Seward, Miriam I. Krauss +4
The region around the Car nebula has three OB associations, which contain a Wolf-Rayet star and several massive O3 stars. An early Chandra ACIS-I image was centered on Car…
Chandra Observation of the X-Ray Source Population of NGC 6946
S. S. Holt, E. M. Schlegel, U. Hwang +1
We present the results of a study of discrete X-ray sources in NGC 6946 using a deep Chandra ACIS observation. Based on the slope of the log N-log S distribution and the general co…
Upper Limits on the X-ray Emission of "Uranium" Stars
Eric M. Schlegel
A paper by Qian & Wasserburg suggests the optical absorption lines of uranium observed in the spectra of ultra-metal-poor stars (defined as [Fe/H] -3) arise from contamination f…
