Over the past 20 years the HETGS has been a key to unlocking the dynamics of the wind-wind collision and the nature of the hidden companion star. The AO 21 interval includes the next periastron passage, offering us a view of the hot gas in the wind-wind bow shock as it plunges towards the primary. We request Chandra and HST imaging spectrometry to uniquely probe the wind-wind shock on scales from the stellar separation to 100s of AU. These observations and our approved AO20 HETG Eta Car observations (not yet obtained), with new imaging with VLTI/MATISSE, and previous X-ray spectra from Chandra and other instruments will provide a detailed view of the colliding wind shock structure and the nature of the companion. The four HST/STIS orbits are committed to monitor the FUV spectral changes as the X-ray flux peaks, then drops through the minimum. ------------------------------------------------------------------------------------ Observations Description ------------------------ The four orbits will be dedicated to single orbit visits recording the FUV spectra in coordination with the X-ray spectroscopic visits by CHANDRA. Visibiilty has evolved for Eta Carinae. Previously it has been accessible for nominal orbits throughout the year, but apparently is less accessible. The projected windos, 19-Dec-31 Dec-2019, 8-Feb- to 24 Feb-2020 and 20-Mar-13-Apr-2020 do not align as well as anticipated during the proposal cycle. The best match appears to beas follow: CHANDRA visit WINDOW HST VISIT APT PLANNING HST/STIS WINDOW 1-3 5 Jan to 5 Feb-2020 1 28 to 31-DEC-2019 (two or three visits planned for 15992( 9) - 17-Feb-2020 20:11:45 - [ 2] CHANDRA grating) 4 18 to 25 Feb-2020 2 8 to 24-FEB-2020 Visit with CHANDRA/ACIS 5 29-Feb to 8-MAR-2020 3 20 to 31-MAR-2020 2nd visit with CHANDRA/ACIS 4 1 to 18-APR-2020 Followup during late portion of low state ------------------------------------------------------------------------------------ 15992( 9) - 17-Feb-2020 20:11:45 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 -ETA-CAR STAR, ETA CARINAE STAR, RA=10H45M3.5910S +/- .2", J2000 V = 4.8 +/- .3 2e-11 erg cm2 s at 1400A WOLF RAYET - WN DEC=-59D41'4.26" +/- .2", PLATE-ID=ZZZQ Reference Frame: GSC1 Extended: NO Comments: This utilizes special astrometry that has been accurate for observations from 2000 to 2019. The stated flux is an upper limit as historically Eta Car begins to fade in the UV a few months before periastron. However, being very cautious of the MAMA global count rate, we shift from E140M to E140H.
