    • ABSOLUTE PROPER MOTIONS OUTSIDE the PLANE (APOP) - A STEP TOWARD the GSC2.4 

      Qi, Zhaoxiang; Yu, Yong; Bucciarelli, Beatrice; Lattanzi, Mario G.; Smart, Richard L.; Spagna, Alessandro; McLean, Brian J.; Tang, Zhenghong; Jones, H.R.A.; Morbidelli, Roberto; Nicastro, Luciano; Vecchiato, Alberto (2015-10-06)
      We present a new catalog of absolute proper motions and updated positions derived from the same Space Telescope Science Institute digitized Schmidt survey plates utilized for the construction of Guide Star Catalog II. As ...

    • Evidence for orbital motion of CW Leonis from ground-based astrometry 

      Sozzetti, A.; Smart, R. L.; Drimmel, R.; Giacobbe, P.; Lattanzi, Mario G. (2017-10)
      Recent Atacama Large Millimeter/submillimeter Array (ALMA) observations indicate that CW Leo, the closest carbon-rich asymptotic giant branch star to Sun, might have a low-mass stellar companion. We present archival ...

    • The kinematic signature of the Galactic warp in Gaia DR1 : I. the H ipparcos subsample 

      Poggio, E.; Drimmel, R.; Smart, R. L.; Spagna, A.; Lattanzi, Mario G. (2017-05-15)
      Context. The mechanism responsible for the warp of our Galaxy, as well as its dynamical nature, continues to remain unknown. With the advent of high precision astrometry, new horizons have been opened for detecting the ...
