The program is a vast resource of data on the star, most notably high-resolution spectra taken with Hubble’s Space Telescope Imaging Spectrograph (STIS). The instrument ceased working in late 2004.
“No other instrument that exists in reality or on a designer’s work table will be able to do what STIS did for our understanding of Eta Carinae,” Martin declares. “We’re partially blinded now and we aren’t learning as much as we had been.”
Associate Editor Francis Reddy spoke with Martin at the American Astronomical Society’s Seattle meeting January 10, 2007.
