Computer-readable version of General Catalogue of Variable Stars, Vol.V. Extragalactic Variable Stars. ... Sample lines of the data files I. INTRODUCTION ------------------ The present fifth (and the last) volume of the 4th Edition of the General Catalogue of Variable Stars (GCVS) is our first attempt to collect in a unified form the data for all variable and suspected variable stars - either members of extragalactic systems or observed in the direction of such systems due to projection. ...
... Here is a brief outline of the current theory of the events in the early history of the solar system: . A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. ... The gas cools off enough for the metal, rock and (far enough from the forming star) ice to condense out into tiny particles. (i.e. some of the gas turns back into dust). ... Once the larger of these particles get big enough to have a nontrivial gravity, their growth accelerates. ...

... The distance scales of the objects are matched both by comparing the first derivatives of the angular velocity determined separately from radial velocities and proper motions and by the statistical-parallax method. ... Good agreement between the inferred 0 and our calculations based on space velocities suggests that the Lindblad relation holds throughout the entire sample volume. ...
