Contains the BinaryMassFunction class, with the following methods: calc_y - calculates the modified mass function given the binary orbital parameters. calc_q_minimum - calculates the minimal mass-ratio possible for a given value of reduced mass function. calc_S - calculates the modified mass func...

stars: luminosity function, mass functionstars: pre-main sequenceWe present a statistical comparison of the mass ratio distribution of companions, as observed in different multiplicity surveys, to the most recent estimate of the single-object mass function. The main goal of our analysis is to test...
In addition, there are also significantly uncertainties about the BPS method itself due to weak constraints on initial conditions adopted for BPS studies such as the initial mass function (IMF), star-formation rates, binary fraction, and the distributions of mass ratios and orbital periods (see ...
which in turn are a function of the progenitor binary masses and equation of state (EoS). The incidence of jets in the population therefore carries information about the binary component mass distribution and EoS. Under the assumption that a jet can only be produced by a black hole remnant su...
One is the central star in the disk, if it is still rapidly rotating, may deform to a barlike shape, which can pinch off a low-mass component. The core may undergo spontaneous fission into fragments, which then evolve separately. Simulations show, however, that the fission scenario does ...
The bulk data collection and Internet Connection Record proposals open the door to mass state surveillance and are in violation of Article 8 of the European Convention on Human Rights. Nothing less than our right to privacy is at stake.
Physical Binary a binary star whose components are bound by mutual gravitational attraction and orbit a common center of mass. In addition to most visual binaries, physical binaries include spectroscopic binaries, eclipsing binaries, and stars that have dark companions. ...
Let f(n) be the number of 1s in the frame number n, i.e., f(n) is the number of detected moving blocks as function of frame number. The finite difference approximation of first derivative of f is used to monitor the reliability of the motion feature. If the jump in values of f ...
