, 1999 The new approach outlined in Paper I (Spurzem \& Giersz 1996) to follow the individual formation and evolution of binaries in an evolving, equal point-mass star cluster is extended for the self-consistent treatment of relaxation and close three- and four-

Beyond binaries : a way forward for comparativeeducation
Revista Española de Educación Comparada, 2012 Binary discourses shape and produce the stories we construct about the field of comparative education. In the first part of this article, I review a set of binary discourses that have characterized social science research since the Enlightenment ...

Limits of Binaries That Can Be Characterized by Gravitational Microlensing
, 2008 Due to the high efficiency of planet detections, current microlensing planet searches focus on high-magnification events. High-magnification events are sensitive to remote binary companions as well and thus a sample of wide-separation binaries are ...

Binary Asteroid Encounters with Terrestrial Planets: Timescales and Effects
, 2011 Many asteroids that make close encounters with terrestrial planets are in a binary configuration. Here we calculate the relevant encounter timescales and investigate the effects of encounters on a binary's mutual orbit. We use a combination of analytical

Symposium - 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 ...

The "Binarity and Magnetic Interactions in various classes of Stars" (BinaMIcS) project
, 2015 The "Binarity and Magnetic Interactions in various classes of stars" (BinaMIcS) project is based on two large programs of spectropolarimetric observations with ESPaDOnS at CFHT and Narval at TBL.

A Spectroscopic Study of Field and Runaway OB Stars
, 2006 Identifying binaries among runaway O- and B-type stars offers valuable insight into the evolution of open clusters and close binary stars. Here we present a spectroscopic investigation of 12 known or suspected binaries among field and runaway OB stars ...

W 50 Morphology and the Dynamics of SS 433 Formation—The Origin of TeV Gammas from the Microquasar
ParticlesThe precessing jets of microquasar SS 433 have punched through the supernova remnant W 50 from the explosion forming the compact object. The jets collimate before reaching beyond the shell, some 40 pc downstream, just the region of origin of TeV gamma ...

Young Binary Stars and Associated Disks [PDF]
, 1999 The typical product of the star formation process is a binary star. Binaries have provided the first dynamical measures of the masses of pre-main-sequence (PMS) stars, providing support for the calibrations of PMS evolutionary tracks.

Linking the fate of massive black hole binaries to the active galactic nuclei luminosity function
, 2015 Massive black hole binaries are naturally predicted in the context of the hierarchical model of structure formation. The binaries that manage to lose most of their angular momentum can coalesce to form a single remnant. In the last stages of this process,
