Definition of the Celestial Ephemeris Origin and of UT 1 in the International Celestial Reference Frame ?
The adoption of the International Celestial Reference System ICRS, and of the corresponding Frame, ICRF, by the 23rd General Assembly of the International Astronomical Union, calls for a redefinition of the departure point on the true equator. Several possibilities have been suggested. This paper considers the use of the non-rotating origin (Guinot 1979). The " Celestial Ephemeris Origin " (CEO...
متن کاملAstrometric Effects of Secular Aberration
One of the main endeavors of fundamental astrometry is to establish a practical realization of a non-rotating, inertial reference frame anchored to celestial objects whose positions are defined in the barycentric coordinates of the solar system matching the current level of astrometric observational accuracy. The development of astrometric facilities operating from space at a microarcsecond lev...
متن کاملConnecting VLBI and Gaia Celestial Reference Frames
The current state of the link problem between radio and optical celestial reference frames is considered. The main objectives of the investigations in this direction during the next few years are the preparation of a comparison and the mutual orientation and rotation between the opticalGaia Celestial Reference Frame (GCRF) and the 3rd generation radio International Celestial Reference Frame (IC...
متن کاملa contrastive study of rhetorical functions of citation in iranian and international elt scopus journals
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
Reference Frames for Stellar Aberration
There is some confusion in the literature as to what velocity should appear in the stellar aberration formula. Because the aberration formula is usually derived from the same equations as the Doppler shift, where the relative velocity between source and detector is the relevant one, it is often assumed the same holds for aberration. This is not the case. Authors who choose the orbital velocity ...
