The Census of Exoplanets in Visual Binaries: population trends from a volume-limited Gaia DR2 and literature search [PDF]
, 2021 We present an extensive search in the literature and Gaia DR2 for visual co-moving binary companions to stars hosting exoplanets and brown dwarfs within 200 pc.

The spin-orbit alignment of visual binaries
, 2020 Context. The angle between the stellar spin-axis and the orbital plane of a stellar or planetary companion has important implications for the formation and evolution of such systems.

Visual Binaries: Cross-Matching and Compiling of a Comprehensive List
, 2015 Visual binary stars make up the largest set among observed types of binaries (currently more than 110 000 systems are known containing more than 230 000 components).

Eclipsing binaries from the cstar project at Dome A, Antarctica
, 2015 The Chinese Small Telescope ARray (CSTAR) has observed an area around the Celestial South Pole at Dome A since 2008. About 20,000 light curves in the i band were obtained during the observation season lasting from 2008 March to July.

Orbital constraints for young low-mass visual M-dwarf binaries
, 2021 We have procured astrometric epochs for 15 low-mass visual M-dwarf binaries for which we are able to place orbital constraints. From the Keplerian motions of the binaries we are able to extract dynamical masses, which will be compared to current state-of-

Co-regulation, video-on-demand, and the legal status of audio-visual media [PDF]
, 2010 Media regulation in the United Kingdom has traditionally seen a division between State regulation (in the case of broadcasting) and self-regulation (in the case of newspapers), both subject to laws of general application.

Ephemerides of Visual Binaries of highly eccentric orbits [PDF]
, 2013 Ephemerides of binary stars are important information for astronomical observation and research. In this paper, ephemerides of the visual binaries ADS784, ADS13665, A1529, ADS836, ADS 3434, ADS1105 and ADS 3315 have been calculated using a computational ...

Visual binaries among high-mass stars
, 2001 We have searched for visual binaries with projected separations in the range 200-3000 AU (0$\farcs$1-1$\farcs$5) among a sample of 96 stars in the massive young NGC 6611 cluster, 60 of them being subsequently identified as high probability cluster ...

Statistical Analysis of a Comprehensive List of Visual Binaries
, 2015 Visual binary stars are the most abundant class of observed binaries. The most comprehensive list of data on visual binaries compiled recently by cross-matching the largest catalogues of visual binaries allowed a statistical investigation of ...
