Identifier: http://hdl.handle.net/1959.14/1066706
Description: The two Large Magellanic Cloud star clusters, NGC 1805 and NGC 1818, are approximately the same chronological age (~30 Myr), but show different radial trends in binary frequency. The F-type stars (1.3 ... More

Identifier: http://hdl.handle.net/1959.14/296204
Description: The R Coronae Borealis (RCB) stars are hydrogen-deficient, variable stars that are most likely the result of He-CO WD mergers. They display extremely low oxygen isotopic ratios, ¹⁶O/¹⁸O ≃ 1-10, ¹²C/¹³ ... More
