" Eta Carinae Superstar "

Kenji Hamaguchi

(NASA/GSFC & UMBC)


Eta Carinae is the best studied supermassive star on the way to end its life as a supernova or hypernova explosion and/or a gamma-ray burst. Intensive multi-wavelength observations since the late 1990's uncovered evidence of a binary system at the core of the bipolar envelope ejected in the Great Eruption of the 1840's. However, the characteristics of the two stellar components are not well constrained as they are deeply cloaked in their massive interacting winds. I introduce the latest picture of Eta Carinae obtained from an observing campaign heavily focused on 2003 and 2008-9 observing seasons, coincident with the two most recent periastron passages.


Seminars are also held at JAC, CFHT, and IfA.
