Soft X-ray Spectrum Changes over the 35-Day Cycle in Hercules X-1 Observed with AstroSat SXT

Universe
Observations of the X-ray binary system Her X-1 by the AstroSat Soft X-ray Telescope (SXT) were carried out in 2020 through 2023 with the goals of measuring X-ray spectrum changes with the 35-day disk precession phase and measuring eclipses at different ...

Constraining the Mass Loss Geometry of Beta Lyrae [PDF]

Journal of Astronomy and Space Sciences, 2012
Massive binary stars lose mass by two mechanisms: jet-driven mass loss during periods of active mass transfer and by wind-driven mass loss. Beta Lyrae is an eclipsing, semi-detached binary whose state of active mass transfer provides a unique ...

Eclipsing Binaries From the CSTAR Project at Dome A, Antarctica [PDF]

, 2015
The Chinese Small Telescope ARray (CSTAR) has observed an area around the Celestial South Pole at Dome A since 2008. About $20,000$ light curves in the i band were obtained lasting from March to July, 2008. The photometric precision achieves about 4 mmag

Slim binaries

Communications of the ACM, 1997
The traditional path to software portability among various hardware platforms has been the provision of "fat binaries", object files that contain multiple instruction sequences for different target architectures. This paper presents an alternative approach based on "slim binaries", files that contain a target-machine-independent program representation ...

Correction of UBV Photometry for Emission Lines

Open Astronomy, 2003
We investigate the effect on U,B,V magnitudes of the removal of emission lines from the spectra of some symbiotic stars and novae during their nebular phases.

A stochastic Monte Carlo approach to model real star cluster evolution, III. Direct integrations of three- and four-body interactions [PDF]

, 2003
Spherically symmetric equal mass star clusters containing a large amount of primordial binaries are studied using a hybrid method, consisting of a gas dynamical model for single stars and a Monte Carlo treatment for relaxation of binaries and the setup ...

Body, identity and ideology discourse

Fluminensia: Journal for Philological Research, 2008
The paper explores ideology influence in formation of bodily mediated personal identity. The ideology discourse is being analyzed in relation towards cultural and social hegemonic praxis as a frame in which the ways of social and individual estimates of ...

High Velocity Spectroscopic Binary Orbits from Photoelectric Radial Velocities: BD+20 5152, a Possible Triple System

Open Astronomy, 2010
The spectroscopic orbit of a high proper motion star, BD+20 5152, is calculated from 34 CORAVEL-type radial velocity measurements. The star has a slightly eccentric orbit with a period of 5.70613 d, half-amplitude of 47.7 km/s and eccentricity of 0.049 ...
