Henbest, Nigel
June 1991
New Scientist;6/8/91, Vol. 130 Issue 1772, p24
Discusses the continuing debate over whether our galaxy started suddenly or slowly, and details new evidence that supports the slow start hypothesis. Work of Bob Dickens and his colleagues using the Anglo-Australian Telescope in New South Wales; Studying globular clusters; Difficulty in measuring the age of individual stars; Comment of British astronomer Martin Rees; Differences in age between NGC 288 and NGC 362.

    We reviewed the recent progress in the field of stellar/galactic archeology, which is a study of the relics from the early galaxy. The oldest and most pristine objects that can be observed in the galaxy are the low mass metal poor stars of the Milky Way. They were formed during the early phases,...

    I review the observational constraints on the stars responsible for the upturn in the UV spectra of ellipticals, ranging from galaxies in the local Universe to distant clusters. In nearby galaxies, this UV upturn is produced by a minority population of extreme horizontal branch (EHB) stars, with...
