dc.description.abstractSALT spectra of the helium-rich hot subdwarf EC 22536-5304 show strong absorption lines of triply ionized lead. Analysis of the HRS spectrum and a follow-up SALT/RSS spectrum show EC 22536-5304 to have surface properties (temperature, gravity, helium/hydrogen ratio) similar to other heavy-metal subdwarfs. With a lead overabundance of 4.8 dex relative to solar, EC 22536-5304 is the most lead-rich intermediate helium subdwarf discovered so far.
