The BSN Application-I: Photometric Light Curve Solutions of Contact Binary Systems [PDF]

open access: goldGalaxies
Light curve analysis of W UMa-type contact binary systems using MCMC or MC methods can be time-consuming, primarily because the repeated generation of synthetic light curves tends to be relatively slow during the fitting process.

On Exotic Objects Made of Dark Energy and Dark Matter: Mass-to-Radius Profiles and Tidal Love Numbers

open access: yesGalaxies, 2023
We investigate some properties of exotic spherical configurations made of dark matter and dark energy. For the former, we adopt a polytropic equation-of-state, while for the latter, we adopt the extended Chaplygin gas equation-of-state.

Analyzing Binary Relationships of Identity Labels Using Distributional Semantic Models

open access: yesIperstoria, 2023
Following the shift towards quantitative, corpus-based analysis in queer linguistics, I examine the usage of identity labels to explore the binary relationships and predicted normative effects in the case of the online community r/lgbt, a subreddit ...

Beyond binaries and before becoming: Reconsidering resistance in UK higher education

open access: yesPRISM, 2021
 Drawing from the tensions within non-representational and human practice perspectives on affect, this paper continues the task of re-conceptualising academic-level resistance in the context of UK higher education.

Under-Developed and Under-Utilized Eclipsing Binary Model Capabilities [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2012
Existing but largely unused binary star model capabilities are examined. An easily implemented scheme is parameterization of starspot growth and decay that can stimulate work on outer convection zones and their dynamos.

EITHER/ OR, AND BEYOND [PDF]

open access: yesIncursiuni în imaginar, 2023
Reality and fiction build a binary which shared the fate of dualist thinking in general in the postmodernist age, dominated by deconstruction. The climactic point was probably reached by the fabrication of lens which magnify reality.

THE DEPENDENCE OF ON- AND OFF-STATE GENERATIONS IN CLASSICAL MICROQUASARS FROM THE DISK DENSITY. 3-D NUMERICAL HYDRODYNAMICAL SIMULATIONS OF THE HIGH AND LOW MASS ACCRETION RATE IN ACCRETION DISK IN MICROQUASAR CYG X-1

open access: yesOdessa Astronomical Publications, 2018
In the present work we have computed and have compared the on- and off- generations in low and high mass accretion rate accretion disks. The comparison shows that in the case of low mass accretion rate in disk (10−10 solar mass per year) the ON-state time

Optical Observations with Milliarcsecond Resolution of Stars, Their Environments and Companions [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2012
Observations with milliarsecond resolution using the Navy Optical Interferometer have been obtained for a number of stellar systems which include high-mass binaries, eclipsing binaries, and radio stars.

The LISA Gravitational Wave Foreground: A Study of Double White Dwarfs [PDF]

open access: yes, 1995
Double white dwarfs are expected to be a source of confusion-limited noise for the future gravitational wave observatory LISA. In a specific frequency range, this 'foreground noise' is predicted to rise above the instrumental noise and hinder the ...

Analysis of the eclipsing binaries in the LMC discovered by OGLE: Period distribution and frequency of the short-period binaries [PDF]

open access: yes, 2006
We review the results of our analysis of the OGLE LMC eclipsing binaries (Mazeh, Tamuz & North 2006), using EBAS -- Eclipsing Binary Automated Solver, an automated algorithm to fit lightcurves of eclipsing binaries (Tamuz, Mazeh & North 2006).
