Infrared Observations of Eta Carinae


Eta Carinae is a non-stellar object less than 5" in diameter seen projected on a region of dense nebulosity. Spectroscopic observations, reviewed by Rodgers and Searle (1967) and Aller (1966) have shown strong emission lines superimposed on a smooth continuum. This continuum contributes about 60 per cent of the visual energy and rises steeply into the infrared; no entirely satisfactory mechanism for producing this radiation has been proposed. In this Letter photometric data which extend the continuum observations to 1.65, 2.2, and 3.4 μ are presented.
