UY Sextantis
UY Sextantis is a post-AGB blue-white subdwarf star, located in the constellation of Sextans. The star is classed as member of the V361 Hydrae type (or also called sdBVr type) class of pulsators in the field of asteroseismology, although it is now generally classified as class O. No additional stellar companion has been detected in tight orbit or imaged around the subdwarf star.
The star's variability was discovered in 1998 by D. O'Donoghue et al.. It was given its variable star designation in 2000. It has an apparent magnitude of 13.5 and the brightness changes amount to less than 0.1 magnitudes, with a typical period of 142 seconds.
