Variable star in the constellation Virgo
32 Virginis , also known asFM Virginis , is a star located about 250light years from the Earth, in the constellationVirgo .[ 2] apparent magnitude ranges from 5.20 to 5.28, making it faintly visible to thenaked eye of an observer well away fromcity lights .[ 3] [ 11] Delta Scuti variable star which oscillates with a dominant period of 103.51 minutes.[ 11]
In 1914,Walter Sydney Adams announced that 32 Virginis is aspectroscopic binary .[ 12] [ 13] et al. made photometric observations of the star in early 1971, and found that the star showed variability due to pulsations.[ 14] variable star designation FM Virginis.[ 15] Donald Kurtz et al. determined that the star was a Delta Scuti variable, in 1976.[ 8]
The primary star is believed to be anAm star similar torho Puppis - a pulsating post-main sequence star.[ 16]
