SPECTROSCOPIC BINARY ORBITS FROM PHOTOELECTRIC RADIAL VELOCITIES PAPER 250: THE CEPHEID BINARY AW PERSEI (HD 30282)

摘要

This issue sees a remarkable event in the annals of astronomy: Paper 250 in the series by Professor Roger Griffin on Spectroscopic Binary Orbits from Photoelectric Radial Velocities. It is remarkable not only for the number of papers published and the number of stars treated to a rigorous examination, but also for the fact that the whole approach -- now used routinely for research at the forefront of astronomy, such as exoplanet discovery -- was pioneered by the author and has been pursued relentlessly by him for over 40 years. And if the series in these pages was not enough, Roger has been prolific with papers on the same topic in several other journals, particularly the Indian Journal of Astrophysics and Astronomy. The dedication he has shown to observing with a modest telescope --and thus one of little interest to 'the thundering herd' -- at Cambridge， with its less-than-ideal climate, is heroic indeed and amazingly shows little sign of abatement in spite of his 80 years. Roger's impact on astronomy has been impressive and this issue collects a number of tributes as letters from colleagues who have benefitted from his work.
