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.

On Variation Mechanisms in Recurrent Nova IM Normae

open access: yesGalaxies, 2022
Light curves by Woudt and Warner (WW) of recurrent nova IM Nor show eclipse-like dips that they saw as too wide for eclipses alone, and interpreted as mainly a reflection effect due to irradiation of the companion (mass donor) star with some amplitude ...

Parameterization of long-period eclipsing binaries

open access: yesOpen Astronomy, 2022
One of the important sources for independent determination of stellar masses is eclipsing binaries with components on the main sequence, and with observable spectral lines of both components.

Milli-arcsecond binaries [PDF]

open access: yesProceedings of the International Astronomical Union, 2007
AbstractAs part of an astrometric program (see Loinard et al. in this volume), we have obtained an unprecedented sample of high-resolution (~ 1 mas) VLBA images of several nearby young stellar systems. As was to be expected, these images revealed interesting new characteristics of these objects.

Binary cosmic strings [PDF]

open access: yesPhysical Review D, 1996
The properties of cosmic strings have been investigated in detail for their implications in early-universe cosmology. Although many variations of the basic structure have been discovered, with implications for both the microscopic and macroscopic properties of cosmic strings, the cylindrical symmetry of the short-distance structure of the string is ...

Binary–binary scattering in the secular limit [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT Binary–binary interactions are important in a number of astrophysical contexts including dense stellar systems such as globular clusters. Although less frequent than binary–single encounters, binary–binary interactions lead to a much richer range of possibilities such as the formation of stable triple systems.

Cool Companions to White Dwarfs from the 2MASS Second Incremental Data Release [PDF]

open access: yes, 2002
We present near-infrared magnitudes for all white dwarfs (selected from the catalog of McCook & Sion) contained in the 2 Micron All Sky Survey Second Incremental Data Release(2MASS 2IDR). We show that the near-IR color-color diagram is an effective means

Binary consensus through binary communication [PDF]

open access: yes53rd IEEE Conference on Decision and Control, 2014
The problem of binary consensus for an undirected, synchronous, fixed topology network through noiseless, binary communication is the focus of this paper. We propose a binary consensus protocol that guarantees network convergence to the initial network majority via binary communication among one-hop neighbors.

The Census of Exoplanets in Visual Binaries: Population Trends from a Volume-Limited Gaia DR2 and Literature Search

open access: yesFrontiers in Astronomy and Space Sciences, 2021
We present results from an extensive search in the literature and Gaia DR2 for visual co-moving binary companions to stars hosting exoplanets and brown dwarfs within 200 pc.
