Brian Warner (astronomer)

Brian Warner (25 May 1939 – 5 May 2023) was a British South African optical astronomer who was Emeritus Distinguished Professor of natural philosophy at the University of Cape Town. Warner's research included cataclysmic variable stars, pulsars, degenerate stars and binary stars. He also researched and published on the history of astronomy in South Africa.

Biography

Early life and education

Warner was born 25 May 1939 in Crawley Down, Sussex, England. His father was a gardener on a country estate and his mother was a charwoman. He didn't pass his eleven-plus exam, failing in mathematics, but was nonetheless admitted to the East Grinstead County Grammar School on the recommendation of his teacher. As a schoolboy he befriended the noted amateur astronomer Patrick Moore who lived nearby in East Grinstead where Warner and his friends would use Moore's telescope.

Warner went to University College London (UCL) in 1958 to study undergraduate astronomy. As a student, he was able to use the University of London Observatory. His first two papers were published in 1960, shortly before he graduated. The first in the Journal of the British Astronomical Association on rilles near the lunar crater Pluto, the second in Monthly Notices of the Royal Astronomical Society on the emission spectra of Venus. Warner remained at UCL for postgraduate studies, completing a PhD in astronomical spectroscopy in 1964 titled Abundances in Late type Stars. His doctoral supervisor was Roy Henry Garstang. For his thesis research he travelled to the Radcliffe Observatory in Pretoria, South Africa, to use the observatory's 1.9 m (6.2 ft) telescope.

Career

Warner became a postdoctoral researcher at UCL, before being awarded a Radcliffe-Henry Skynner Fellowship at Balliol College, Oxford, though the university didn't have its own observatory. In 1967 he was recruited to the University of Texas at Austin for his experience in spectroscopy. He also worked with his colleagues Ed Nather and David Evans in developing the new field of high-speed photometry for studying variable stars and measuring stellar radii by observing lunar occultations. In 1972 he was recruited as the first professor of astronomy at the University of Cape Town (UCT) and as head of the astronomy department. Nather also moved to UCT to undertake a PhD, with Warner as his doctoral supervisor. From 1981 to 1983, he served as president of the Royal Society of South Africa. Warner was head of the astronomy department until 1999, before formally retiring in 2004 though he continued to undertake research.

Warner died 5 May 2023 aged 83.
