... The experience of determination of the link between radio sources and dynamical reference frames is presented. To obtain this connection we used a series of very long baseline interferometry (VLBI) observations of the spacecraft Phobos-2 and angularly nearby quasars. ... The dynamical reference frame is determined by equator and equinox of these ephemerides. ... References . ... The relative orientation of the radio and dynamical reference frames can be described by a sequence of three rotations . ...

Next: The Chemical Evolution of Up: Stellar Astrophysics Previous: Stellar Astrophysics . Simon Jeffery has used a novel camera attached to the William Herschel Telescope (WHT) to obtain the best light curves ever obtained for pulsating subdwarf B stars. These stars pulsate non-radially in several modes with different frequencies and enable astronomers to establish their overall properties and internal structure with unusual precision. ...
