An Error Analysis of the Geometric Baade-Wesselink Method
Massimo Marengo, Margarita Karovska, Dimitar D. Sasselov +1
We derive an analytic solution for the minimization problem in the geometric Baade-Wesselink method. This solution allows deriving the distance and mean radius of a pulsating star…
Spatially Resolved Circumnuclear Dust in Centaurus A
Margarita Karovska, Massimo Marengo, Martin Elvis +6
In this paper we present results from our exploratory mid-IR study of Centaurus A circumnuclear environment using high-angular resolution imaging at the Magellan 6.5m telescope wit…
Molecular Hydrogen Emission Lines in Far Ultraviolet Spectroscopic Explorer Observations of Mira B
Brian E. Wood, Margarita Karovska
We present new Far Ultraviolet Spectroscopic Explorer (FUSE) observations of Mira A's wind-accreting companion star, Mira B. We find that the strongest lines in the FUSE spectrum a…
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…
Chandra Multi-wavelength Project (ChaMP). I. First X-ray Source Catalog
D. -W. Kim, R. A. Cameron, J. J. Drake +16
The Chandra Multi-wavelength Project (ChaMP) is a wide-area (~14 deg^2) survey of serendipitous Chandra X-ray sources, aiming to establish fair statistical samples covering a wide…
Theoretical Limb Darkening for Classical Cepheids: II. Corrections for the Geometric Baade-Wesselink Method
Massimo Marengo, Margarita Karovska, Dimitar D. Sasselov +2
The geometric Baade-Wesselink method is one of the most promising techniques for obtaining a better calibration of the Cepheid period-luminosity relation by means of interferometri…
