Toward a Common Language: the Washington Multiplicity Catalog
Due to improvements in technology (interferometers, precision radial-velocity techniques, etc.), the traditional separation/period regimes of “wide” and “close” binaries are witnessing increasing overlap. This is expected to lead to increasing confusion in component identification, since different observing techniques adopted their own rules for designation of these components. A quick overview...
متن کاملThe UCAC3 Star Catalog: A New Catalog of Optical Reference Stars for Space Surveillance
Version three of the U.S. Naval Observatory CCD Astrograph Catalog (UCAC3) was released in August 2009. As the first version of the UCAC to cover the entire sky, UCAC3 is a suitable source of optical reference stars in the R = 8 to 16 magnitude range. Containing just over 100 million objects and providing stellar positional accuracies of about 15 to 100 milliarcseconds (mas) per coordinate, UCA...
متن کاملDouble-Star Detection Using Convolutional Neural Network in Atmospheric Turbulence
In this paper, we investigate the usage of machine learning in the detection and recognition of double stars. To do this, numerous images including one star and double stars are simulated. Then, 100 terms of Zernike expansion with random coefficients are considered as aberrations to impose on the aforementioned images. Also, a telescope with a specific aperture is simulated. In this work, two k...

متن کاملDouble Neutron Star Formation
We present results of a population synthesis study aimed at examining the role of spin-kick alignment in producing a correlation between the spin period of the first-born neutron star and the orbital eccentricity of observed double neutron star binaries in the Galactic disk. We find spin-kick alignment to be compatible with the observed correlation, but not to alleviate the requirements for low...
