 Variable Stars and the Stories They Tell:  

Exoplanets and the Search for Extraterrestrial Life

by Dale Bryant   

Update (July 7, 2015):  I-band coverage of QX Pup by AAVSO observers since 2010 clearly shows that the period given in the 4th Edition of the GCVS of 648: days is incorrect. A phase plot by Sebastián Otero of these data shows that the period of QX Pup in I_c is 551 days.
