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 High Energy X-ray Probe (HEX-P): probing accretion onto stellar mass black holes

open access: yesFrontiers in Astronomy and Space Sciences
Accretion is a universal astrophysical process that plays a key role in cosmic history, from the epoch of reionization to galaxy and stellar formation and evolution. Accreting stellar-mass black holes in X-ray binaries are one of the best laboratories to

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.

Astronomical Data Resources for Binary and Multiple Stars

open access: yesOpen Astronomy, 2015
Binary stars form a significant part of stellar population. They are registered and observed by a number of methods. This is the reason for variety of present-day resources of astronomical data dealing with binaries and multiples.

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.

Secular evolution of compact binaries near massive black holes: gravitational wave sources and other exotica

open access: yes, 2012
The environment near super massive black holes (SMBHs) in galactic nuclei contain a large number of stars and compact objects. A fraction of these are likely to be members of binaries.

Dusty Common Envelope Evolution

open access: yesGalaxies
We present the first hydrodynamical simulations of common envelope evolution that include the formation of dust and the effect of radiation pressure on dust grains.

Contact Binaries [PDF]

open access: yesSymposium - International Astronomical Union, 1986
The most promising mechanism for the formation of contact binaries involves the orbital angular momentum loss (AML) and the resulting orbital decay of detached but close synchronized binaries. The efficiency of magnetic wind braking should abruptly decrease upon formation of a contact binary because of the transformation into a system of earlier ...
