Sasha Hinkley,Laurent Pueyo,Jacqueline K. Faherty,Ben R. Oppenheimer,Eric E. Mamajek,Adam L. Kraus,Emily L. Rice,Michael J. Ireland,Trevor J. David,Lynne A. Hillenbrand,Gautam Vasisht,Eric Cady,Douglas Brenner,Aaron Veicht,Ricky Nilsson,Neil Zimmerman,Ian Parry,Charles Beichman,Richard Dekany,Jennifer E. Roberts,Lewis C. Roberts,Christoph Baranec,Justin R. Crepp,Rick Burruss,J. Kent Wallace,David T. King,Chengxing Zhai,Thomas Lockhart,Michael Shao,Rémi Soummer,Anand Sivaramakrishnan,Louis A. Wilson +31 more
TL;DR: In this paper, the authors present the first spectrum of the companion, "kappa And B," using the Project 1640 high-contrast imaging platform, and compare the low-resolution YJH-band spectra to empirical brown dwarf spectra.
Proceedings ArticleDOI

Ben R. Oppenheimer,Charles Beichman,Douglas Brenner,Rick Burruss,Eric Cady,Justin R. Crepp,Lynne A. Hillenbrand,Sasha Hinkley,E. R. Ligon,T. Lockhart,Ian Parry,Laurent Pueyo,Emily L. Rice,Lewis C. Roberts,Jennifer E. Roberts,Michael Shao,Anand Sivaramakrishnan,Rémi Soummer,Gautam Vasisht,Fred E. Vescelus,J. Kent Wallace,Chengxing Zhai,Neil T. Zimmerman +22 more
TL;DR: Project 1640 as mentioned in this paper is a high-contrast spectral imaging effort involving a coordinated set of instrumentation and software, built at AMNH, JPL, Cambridge and Caltech, and is fully operational.
Journal ArticleDOI
Discovery and Characterization of a Faint Stellar Companion to the A3V Star Zeta Virginis
Sasha Hinkley,Ben R. Oppenheimer,Douglas Brenner,Neil Zimmerman,Neil Zimmerman,Lewis C. Roberts,Ian Parry,Rémi Soummer,Anand Sivaramakrishnan,Anand Sivaramakrishnan,Anand Sivaramakrishnan,Michal Simon,Marshall D. Perrin,David L. King,James P. Lloyd,Antonin Bouchez,Jennifer E. Roberts,Richard Dekany,Charles Beichman,Lynne A. Hillenbrand,Rick Burruss,Michael Shao,Gautam Vasisht +22 more
TL;DR: In this paper, the authors reported the discovery of a faint stellar companion to the A3V star zeta Virginis, which is ~7 magnitudes fainter than its host star in the H-band, and infrared imaging spanning 4.75 years over five epochs indicates this companion has common proper motion with its hoststar.
Journal ArticleDOI

Sasha Hinkley,John D. Monnier,Ben R. Oppenheimer,Lewis C. Roberts,Michael J. Ireland,Neil Zimmerman,Neil Zimmerman,Douglas Brenner,Ian Parry,Frantz Martinache,Olivier Lai,Rémi Soummer,Anand Sivaramakrishnan,Anand Sivaramakrishnan,Anand Sivaramakrishnan,Charles Beichman,Lynne A. Hillenbrand,Ming Zhao,James P. Lloyd,David Bernat,Gautam Vasisht,Justin R. Crepp,Laurent Pueyo,Michael Shao,Marshall D. Perrin,David L. King,Antonin Bouchez,Jennifer E. Roberts,Richard Dekany,Rick Burruss +29 more
TL;DR: In this paper, the authors used adaptive optics images from the Palomar, AEOS, and CFHT telescopes to derive an improved, astrometric characterization of the companion orbit.
Journal ArticleDOI
