Transforming leaky COTS binaries into data-oblivious binaries
… work exists today to transform ""unsafe"" COTS binaries into data-oblivious binaries. Achieving data-oblivious COTS binaries is challenging due to their complex nature and lack of clean abstractions. However, such a feat is necessary because many COTS binaries are already deployed in production …

Beyond binaries
This thesis examines the creative cultural production, consumption and representation of individuals within Britain, classified as of ethnic minority backgrounds. It draws together the fields of 'race', ethnicity and nationality and argues that these wide ranging themes have been conflated to …

Performing Binaries
<p>I take a critical view of sociopolitical and cultural issues dealing with homoeroticism andgay politics. I explore gender theories in order to further understand what it means to bemasculine or feminine and how it affects my placement in society. I use art as a tool forexpressing sexual freedom …

Multimessenger signatures of compact binaries
… I present studies of multimessenger compact binaries from two angles: electromagnetic follow-up of gravitational-waves, and gravitational-wave follow-up of electromagnetic sources. I first describe technical and computational efforts to enable the distribution of alerts of kHz …

Spectral Comparisons of Neutron Star Low-Mass X-Ray Binaries with Black Hole X-Ray Binaries
… X-ray spectra of neutron star low-mass X-ray binaries (LMXBs) allows the investigation of the innermost parts of the accretion disk and immediate surroundings of the compact object. The weak magnetic eld of old neutron stars present in such systems allows the accretion disk to approach very …

Spectral analysis of X-ray binaries
… projects associated with observations of X-ray binaries. Two of those revolve around spectral characteristics of neutron star low-mass X-ray binaries (NS-LMXBs), with a particular source, XTE J1701-462, playing a central role. First, I construct and study color-color and hardness-intensity …

Social Binaries in Contemporary Beur Fiction
… The term is then problematized. The theme of binaries and the third spaces that emerge because of the problematic nature of the binaries is recurring throughout my study. I explore what these third spaces are by examining four contemporary French novels: Faïza Guène’s Kiffe kiffe demain and Un …

The origin and evolution of Transneptunian binaries
… mechanism for producing these transneptunian binaries, where planetesimals and binaries form directly from the gravitational collapse of a pebble cloud. Merging collisions and conservation of angular momentum naturally lead to the formation of similar mass binary objects, and strongly prefers …

Gamma-Ray Observations of X-ray Binaries
<p>The detection of GeV/TeV emission from X-ray binaries (XRBs) has established a new class of high-energy (HE, >0.1 GeV) and very-high-energy (VHE, >100 GeV) gamma-ray emitters. XRBs are formed by a compact object, either a neutron star or a black hole, and by an optical companion star. Some XRBs …

Formation of Low-Mass X-Ray Binaries
… of the origin and properties of low-mass X-ray binaries (compact objects with Roche-lobe filling low-mass companions) by means of population syntheses is presented. A semi-analytical synthesis method that offers major advantages in terms of statistical accuracy and computational efficiency is …

Disk-magnetosphere interaction in X-ray binaries
Binary X-ray pulsars are strongly magnetic neutron stars accreting matter from a companion star. The strong magnetic fields of the neutron stars guide the accreting plasma to the magnetic poles, and X-ray pulsations result from the rotation of the beamed emission at the magnetic poles through the …

Secular Dynamics of Binaries in Stellar Clusters
… interest in the problem of tidally perturbed binaries has surged recently due to the discovery of various exotic astrophysical phenomena, not least the mergers of compact object (black hole and/or neutron star) binaries by the LIGO/Virgo collaboration. The question of how these binaries shrink …

Planetesimal Belts in Misaligned Wide Stellar Binaries
… model of planetesimal belts in wide stellar binaries was created. It found that the occurrence rate of KIC 8462852-like observations in the Kepler field is 10⁻⁸ and hence that the probability of the Kepler telescope observing such phenomena to be 10⁻³. It also found that the systems most …

High Spatial Resolution Observations of Young Stellar Binaries
In the first part of this work a volume-limited multiplicity survey with magnitude cutoff (m_K <= 10.5 mag) of 158 young stellar objects located in the Ophiuchus molecular clouds is presented. All companions in the separation range 0.13 arcsec to 6.4 arcsec with flux ratios >= 0.1 at the …

MODELING X-RAY DATA OF BLACK HOLE BINARIES
We test the truncated disc models using multiwavelength (optical/UV/X-ray) data from the 2005 hard state outburst of the black hole SWIFT J1753.5-0127. This system is both fairly bright and has fairly low interstellar absorption, so gives one of the best datasets to study the weak, cool disc …

The galactic population of binaries containing neutron stars
… fate of low-, intermediate-, and high-mass X-ray binaries (L/I/HMXBs). The primary theoretical tool used throughout is binary population synthesis. Results of these calculations are used to account for the numbers and properties of observed X-ray binaries and their descendants, as well as to …

Eclipsing Binaries and Period Changes in the SuperWASP Archive
… project has been to investigate eclipsing binaries using archival data from the SuperWASP (Wide Angle Search for Planets) survey, and specifically to search for evidence of orbital period variations. The short cadence and long time base of SuperWASP light curves make them highly suitable …

Accretion and outflow in black-hole x-ray binaries
Black hole X-ray binaries (BHXBs) are stellar binary systems consisting of a black hole (BH) and a companion star. They are known to produce X-ray emission through the accretion of mass from the companion star onto the black hole via an accretion disc, as well as radio emission originating from …
