Description

High Quality Content by WIKIPEDIA articles! Przybylski's Star (or HD 101065) is a peculiar star that is located about 410 light years from the Sun in the constellation Centaurus. In 1961, the Polish-Australian astronomer Antoni Przybylski discovered that this star had a peculiar spectrum that would not fit into the standard framework for stellar classification. Przybylski's observations indicated unusually low amounts of iron and nickel in the star's spectrum, but higher amounts of unusual elements like strontium, niobium, scandium, yttrium, caesium, neodymium, praseodymium, thorium, ytterbium, and uranium. In fact, at first Przybylski doubted that iron was present in the spectrum at all. Modern work shows that the iron-group elements are somewhat below normal in abundance, but it's clear that the lanthanoids and other exotic elements are highly overabundant. As a result of these peculiar abundances this star belongs firmly in the Ap star class.
