Virpi Sinikka Niemela, Finnish-born Argentine astronomer (Helsinki 26 December 1936 – La Plata 18 December 2006)

Authored over 130 papers about massive stars

First to show that stars with Wolf-Rayet emission spectrum display absorption intrinsic lines too

Discovered and analysed spectroscopic orbits of many binary systems with Wolf-Rayet component in Southern Hemisphere

Proposed the analysis of interstellar medium around Theta Muscae in order to find his HI interstellar bubble
