This is an update of Cycle 20 of a three cycle program. The single visit planned for summer of 2013 has now been split into three one-orbit visits in response to newer 3D hydrodynamic models. Cycle 21 program remains as three three-orbit visits to be scheduled at very critical intervals to test the 3D models. Results from the cycle 20 program will provide two checks on how the interacting binary winds are evolving as periastron approaches. The third visit is expected to produce a null [Fe III] map and strong [Fe II] map just after periastron. Visit 2 has been shifted to August 2014 to adjust for calibration, schedule and resources issues. This is being done in parallel with submission of third and final cycle of this three cycle program, program 13395. Submission 4: a very minor change to the patterns as Eta Carinae has stabilized in brightness allowing us to cut back on the small pattern and expand the large pattern to the desired full two arcseconds. This applies to visits two and three as one is accomplished. A similar change was submitted for program 13395. 1810485743 ----- Attempting Submission 2 (Wed Jan 02 19:53:50 GMT 2013) ----- ----- Attempting Submission 3 (Mon Jun 10 19:41:50 GMT 2013) ----- ----- Attempting Submission 4 (Tue Oct 08 19:54:12 GMT 2013) ----- Constraining the evolutionary state of the hot, massive companion star and the wind-wind collision region in Eta Carinae Our primary goal is to constrain the physical properties of Eta Car's wind-wind collision region and the properties of Eta Car B, the hot, very massive secondary companion that is hidden from our view. We propose to do this by measuring the forbidden emission lines in the extended, interacting wind structures resolved in the inner 1.5 arcseconds region. As the mass-loss structures evolve across the 5.54-year orbital period, we will selectively map their spatial and velocity changes at critical phases using the spatial resolution of HST and moderate spectral resolving power of the STIS to generate spatial (2-D), velocity (1-D) data cubes of regions of critical collisional densities. We will use these spatial-velocity data cubes to drive ongoing 3-D models of the interacting winds, adding radiative transfer. We will (A) strongly constrain the 3-D mass loss from the system and (B) determine the properties of Eta Car B, the source of FUV radiation and the driving wind creating the X-ray emitting cavity out of the dominating wind of Eta Car A. These observations are planned to observe the extended winds of Eta Carinae at critical times to test current and developing 3D hydrodynamic models that eventually will incorporate radiative transfer. Each visit will map the 1.5" extended winds in forbidden emission lines of high and low ionization species including Fe++, Ar++, N+, Fe+ and Ni+. CVZ is requested to obtain complete mappings in each of these lines using one G430M grating setting (4706A) and two G750M grating settings (7354 abd 5734). The mapping is accomplished with a 52"X0.1" aperture at arbitrary position angles, sampled at 0.05" spacing. The observations under this specific program will occur at apastron (phase 0.8) in mid-2012. Cycle 19 observations, under program 12508 occurred at (phase 0.5) in fall 2011. Cycle 21 is intended to begin weeks before periastron (phase 0.98) in June 2014, and will sample at two critical phases just after periastron in fall 2015 (near phases 1.06 and 1.09). We anticipate a very asymmetric recovery structure in [Fe III] and [Ar III] near phase 1.06 with symmetry accomplished by 1.09. The reference phase for structure is at apastron and maximum structures should be between phase 0.8 and 0.98. Mappings now exist for phases 0.084, 0.163, 0.323, 0.466 from programs 11506, 12013, 13508 and have been fitted by SPH modeling (in preparation). January 2013 addenda: Having examined current 3D hydrodynamic models run by Dr. Tom Madura, changes to the cycle 20 and cycle 21 phases of the multicycle observing proposal are as follow: The three orbits allocated for Cycle 20 will be used for three single orbit visits using the 4706 grating setting only for mapping of the central 1.75" region. These visits are planned for phase 12.8 in September 2013, phase 12.9 in February 2014 and phase 13.03 in September 2015. Focus will be on changes in [Fe III], He I and He II and [Fe II] The cycle 21 program continues to be three three orbit visits using 4706, 5755 and 7283 grating settings. They are planned for near 12.985, June 7 2014, phase 13.06 near November 21, 2014 and 13.09 near January 15 2015. Focus will enlarge to include [N II], He I, [Ar III], [Fe II] and [Ni II] emissions.
