Speckle observations with PISCO in Merate (Italy): XVI. Astrometric measurements of visual binaries in 2015, and new orbits for DUN 5, ADS 5958, 6276, 7294, 8211, and 13169

open access: greenAstronomical Notes - Astronomische Nachrichten, 2018
We present relative astrometric measurements of visual binaries, made in 2015 with the speckle camera PISCO at the 102-cm Zeiss telescope of Brera Astronomical Observatory, in Merate.

The spin-orbit alignment of visual binaries [PDF]

open access: bronzeAstronomy & Astrophysics, 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.

SPECKLE INTERFEROMETRY OF SECONDARY COMPONENTS IN NEARBY VISUAL BINARIES* [PDF]

open access: green, 2016
Statistical characterization of secondary subsystems in binaries helps to distinguish between various scenarios of multiple-star formation. The Differential Speckle Survey Instrument was used at the Gemini-N telescope for several hours in 2015 July to ...

The Census of Exoplanets in Visual Binaries: Population Trends from a Volume-Limited Gaia DR2 and Literature Search [PDF]

open access: yesFrontiers in Astronomy and Space Sciences, 2021
We present results from 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.

Spatially resolved spectroscopy of close massive visual binaries with HST/STIS [PDF]

open access: yesAstronomy & Astrophysics, 2020
Context. The spectroscopic characterization of many O-type stars is hampered by a nearby companion. Aims. We want to obtain spatially resolved spectroscopy of close O-type visual binaries to derive their spectral types. Methods.

Deep Binaries: Encoding Semantic-Rich Cues for Efficient Textual-Visual Cross Retrieval [PDF]

open access: yesIEEE International Conference on Computer Vision, 2017
Cross-modal hashing is usually regarded as an effective technique for large-scale textual-visual cross retrieval, where data from different modalities are mapped into a shared Hamming space for matching.

Visual binary stars with known orbits in Gaia EDR3 [PDF]

open access: yes, 2022
3350 objects from the Sixth catalog of orbits of visual binary stars (ORB6) are investigated to validate Gaia EDR3 parallaxes and provide mass estimates for the systems.

Visual Orbits and Alignments of Planet-hosting Binary Systems

open access: yesAstronomical Journal, 2023
Roughly half of Solar-type planet hosts have stellar companions, so understanding how these binary companions affect the formation and evolution of planets is an important component to understanding planetary systems overall.
