Proper and common names: a double dissociation.
Proper name anomia and proper name sparing are unusual disorders characterized by a selective inability, or sparing, to retrieve proper names as opposed to common names. They may eventually demonstrate that these two categories of names are independently processed in the brain at the semantic or lexical/orthographic level. Yet, differences in patient assessment make comparison between cases dif...
متن کاملNew northern common proper motion pairs
A list of 705 new Northern Celestial Hemisphere common proper motion pairs as derived from the Second U.S. Naval Observatory CCD Astrograph Catalog is presented, along with details of their separation, motion, brightness and colour. Objects of particular interest are noted, and the use of the catalogue for such work gauged.
متن کاملProper Motion Studies of Outflows from Classical T Tauri Stars
In a previous paper (McGroarty & Ray, 2004) we examined the environment of a number of evolved low -mass young stars, i.e. Classical T Tauri Stars, to see if they are capable of driving parsec scale outflows. These stars CW Tau, DG Tau, DO Tau, HV Tau C and RW Aur were previously known to drive only “micro jets” or small scale outflows of ≤ 1′ or 0.04 pc at the distance of the Taurus Auriga Clo...
متن کاملCompleteness of USNO-B for High Proper-Motion Stars
I test the completeness of USNO-B detections of high proper-motion (μ > 180mas yr) stars and the accuracy of its measurements by comparing them to the revised NLTT (rNLTT) catalog of Salim & Gould. For 14.5 < V < 18.5, only 6% of such stars are missing from USNO-B while another 4% have large errors, mostly too large to be useful. Including both classes, incompleteness is 10%. These fractions ri...
متن کاملOGLE-II High Proper Motion Stars towards the Galactic centre
The photometry data base of the second phase of the OGLE microlensing experiment, OGLE-II, is a rich source of information about the kinematics and structure of the Galaxy. In this work we use the OGLE-II proper motion catalogue to identify candidate stars which have high proper motions. 521 stars with proper motion μ > 50 mas yr in the OGLE-II proper motion catalogue (Sumi et al. 2004) were cr...
