Helen Battles Sawyer Hogg, CC(1 August 1905- 28 January 1993)was an astronomer noted for pioneering research into globular clusters and variable stars.
Data collected by Kepleris also being used for studying variable stars of various types and performing asteroseismology, particularly on stars showing solar-like oscillations.
Astronomical photography was one of the earliest types of scientific photography and almost from its inception it diversified into subdisciplines that each have a specific goal including star cartography, astrometry, stellar classification, photometry, spectroscopy, polarimetry, and the discovery of astronomical objects such as asteroids, meteors,comets, variable stars, novae, and even unknown planets.
Some of the variable stars, in or near the state of maximum pulsation, are in process of giving origin to subsidiary systems, many of which will eventually be much like your own sun and its revolving planets.
Not limiting herself to publishing her astronomical speciality of variable stars in globular clusters, Hogg published on the history of astronomy through her column"Out of Old Books", which was published in the Journal of the Royal Astronomical Society of Canada.
In addition to her work on variable stars in globular clusters, Hogg used the period-luminosity relationship of Cepheid variable stars(discovered by Henrietta Swan Leavitt in 1908) to enhance the understanding of the Milky Way Galaxy's age, size and structure.
In one group of variable stars the period of light fluctuation is directly dependent on luminosity, and knowledge of this fact enables astronomers to utilize such suns as universe lighthouses or accurate measuring points for the further exploration of distant star clusters.
It has since become a variable star fluctuating between 2.0 and 1.6.
