PI: Dr. Frederick C. Bruhweiler American University Y CoI: Mr. Bruce McCollum American University N ------------------------------------------------------------------------------------ Abstract High-resolution (R~110, 000) HST UV spectra of the very massive LBV, eta Car, reveal interstellar-like extremely narrow, discrete absorption components with line widths ~5 km/s arising from transitions from ground configurations and metastable levels up to 40, 000 cm-1 of Fe-group ions.These features, seen at high negative velocities, arise in dense gas in the near circumstellar environment of eta Car. The implied densities, at least 10^7-8 cm-3, are highly uncharacteristic of the normal ISM. They appear to have originated from clumping in mass outflow of eta Car. IUE spectra show clumping in wind features of other LBVs and has been confirmed by optical observations of Ca II and Fe II. High-resolution UV STIS spectra coupled with proper photoionization modeling offers the only means to detect these extremely narrow absoptions and determine the physical conditions, and line-of-sight distribution (distance from the star) of the ejecta producing the extremelly narrow absoptions. Knowledge of ejecta velocities and distances will permit us to construct a time history for the ejection events. We will obtain and analyze the first high-resolution HST UV spectra of three LBVs having typical masses, and perform the same analysis on archival Eta Car spectra. This information will have many implications for aspects of LBV mass loss, evolution, and wind mechanisms that are not yet understood. ------------------------------------------------------------------------------------ Observations Description ------------------------ We have three LBV targets with a total of 13 orbits: MR35(Visit 1 -1 0rbit & Visit 5- 4 Orbit ) AG Car ( Visit 2 - 2 orbits & Visit 3 - 3 orbits) HD90177( Visit 4 - 3 orbits) In our calculations, we present exposure times for the maximum fluxes seen in archival IUE spectra at each reference wavelength, where there are many spectra for AG Car & HR Car. We will use STIS E140H, E230H, and the E140M echelles. MR35: We request Visit 1, which is only 1 orbit, be executed well before Visit 5, our repeat visit for MR35. We may want to adjust exposures in Visit 5, based upon the fluxes in Visit 1. We expect the fluxes of MR 35 to be lower than the IUE fluxes used. The AAVSO shows MR35 in a flux decline. 17124( 8) - 20-Nov-2023 13:22:57 - [ 2] HST MAMA Detector Safety: AG Car is the UV-brightest of our targets, and as the AAVSO light-curve shows it is currently at V~5.5. We approach the buffer warning limit in a few cases, The maximum global counts we obtain is for AG Car, which is ~13, 000 counts globally for source plus background. Only overexposed IUE spectra exist for Hen 3-591=MR35 (SWP39269 & LWP18410). But IUE/SWP spectra are adequate to estimate flux levels, based upon expected flux distributions of other similar stars. Strong N V 1240 and C IV 1550 in the SWP clearly indicate an O supergiant. The AAVSO light curve shows a flux decline. In most exposures, we try to achieve S/N = 20 or better at the quoted wavelength and flux level. Because of the brightness of our targets in some bandpasses, we often must use the small 0.2"x0.09" and 0.1"x0.03"apertures. Otherwise, we use the 0.2"x0.2" aperture. The declinations of or three targets indicate that we have 57, 57, and 56 min visibility for AG Car, Hen 3-591=MR35, and HR Car=HD 90177. All exposures were calculated using the STIS ETC. We describe our exposures and time overhead for all three targets. These targets have pronounced extinction which is notable by extreme decreased flux near 2200A and shorter wavelengthd. Exposure times vary dramatically across the UV spectrum. ------------------------------------------------------------------------------------ 17124( 8) - 20-Nov-2023 13:22:57 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 V-AG-CAR STAR, LUMINOUS BLUE RA=10H56M11.5681S, J2000 V = 6.96 5E-12 @ 1400A; 5.5E-12 @ VARIABLE DEC=-60D27'12.78" 1650A; 2E-12 @ 2000A; 4E-12 @ 2400A; 1E-11 @ 2900A : LBV Reference Frame: ICRS Extended: NO Comments: Coordinates are from Gaia.
