Kupfuura: The chakarondedzera A-kirasi nyeredzi akadai IK Pegasi A kuratidza simba Balmer mitsetse rehydrogen pamwe absorption mitsetse ionized simbi, kusanganisira K mutsetse ionized karusiyamu (Ca II) panguva wavelength pamusoro 393.3 nm. The chakarondedzera IK Pegasi A iri semuganhu Am (kana "Am:"), izvo zvinoreva kuti anoratidza hunhu ane chakarondedzera kirasi A asi marginally simbi-lined. Ndiko, ichi nyeredzi mhepo inoratidza zvishoma (asi anomalously) yakakwirira pane dzose absorption mutsetse simba kuti simbi isotopes. nyeredzi pamusoro chakarondedzera mhando Am kazhinji nhengo pedyo binaries ane shamwari pamusoro chete gobvu, sezvo zviri nyaya nokuda Pegasi chikuru.
