HST FOC Observations of Eta Carinae
Revista Mexicana de Astronomia Y Astrofisica, v.2,
p.11-16 (1995)
Abstract
The Faint Object Camera (FOC) on the HST was used to observe the inner
regions of n Carinae through the filters F550M, F307M, and F190M.
n Carinae is a very massive LBV with spectacular episodic shell
ejections at an enormous mass loss rate. The new high-resolution
FOC images resolved for the first time at visible and UV wavelengths
the three speckle objects B, C, and D at separations of ~ 0.1 -
0.3". In addition to these objects, new circumstellar structures
were found. The image of the central object A is more extended
than the core of the corresponding PSF. In the two UV images, a
new ring-shaped nebulosity was discovered. We discuss the HST FOC
observation, compare the HST with the diffraction-limited speckle
masking observations at near-IR wavelengths, and discuss the nature and
motion of the objects near the dominant star.
