Red giant line_3: winds can provide the most massive, sustained form of mass transfer in line_4: binaries. The symbiotic and related stars, which contain red giant and hot line_5: companion stars, permit line of sight studies through a range of red giant line_6: atmospheric heights. The goal of this work is to attempt to define both the line_7: mechanism of rapid mass loss in red giant stars and the details of mass line_8: transfer to the companion stars. Such results can provide important line_9: constraints for both stellar and binary evolution theories. line_11: In each case we expect to derive density and temperature values for the red line_12: giant wind region and compare this to the present understanding of single star line_13: conditions where low temperature, dust and molecule forming, circumstellar line_14: envelopes prevail. line_15: (Only EG And observations are included in this file) ! ! end of abstract general_form_proposers: lname: CARPENTER fname: KENNETH mi: G. inst: NASA - GODDARD SPACE FLIGHT CENTER country: USA ! lname: STENCEL fname: ROBERT mi: E. inst: COLORADO, UNIVERSITY OF country: USA ! lname: LINSKY fname: JEFFREY mi: L. inst: COLORADO, UNIVERSITY OF country: USA ! lname: ROBINSON fname: RICHARD mi: D. inst: CSC - ASTRONOMY PROGRAM country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: SUMMARY OF GHRS OBSERVATIONS line_2: OF EG AND line_3: GRAT.

The spectral resolution of IUE line_3: permits velocity determinations (with care) of only +/- 10 km/sec in the far line_4: UV. As a consequence, IUE studies of red giant winds (10-30 km/sec) and narrow line_5: absorption features are handicapped. The superior resolution and dynamic range line_6: of HRS is required. ! question: 5 section: 1 line_1: Please do not schedule EG And observations (#18-30) during line_2: eclipse period (August - September 1993), to ensure line_3: a successfull target acquisition. ! question: 6 section: 1 line_1: Wavelength calibration exposures are required to allow us to obtain the maximum line_2: possible wavelength (and thus velocity) precision possible in the optical line_3: configurations chosen. ! question: 7 section: 1 line_1: Data acquisitions will include spectral calibration. GHRS IDT software line_2: will be used to ensure optimum calibration of the data and to line_3: to derive absolute wavelengths, line_4: fluxes, and profile characteristics of observed spectral features. This done, line_5: lines of CI Cyg can be examined for profile asymmetries and systematic line_6: velocity differences. For CI Cyg and EG And, the O IV density diagnostic will line_7: be used. For EG And, the instrinsic profiles of the transient HE II 1640 A line_8: absorption and the complex C IV 1550 A features determined. In both cases, line_9: important fiducial observations will thus be obtained for further HST study of line_10: these very long period systems. ! question: 12 section: 1 line_1: The targets observed in this program are: line_3: 1.

EG And (rerun of cycle 1 program, this file) ! question: 13 section: 1 line_1: Two "symbiotic stars" (CI Cyg + EG And) will be studied with HRS, for their line_2: line and continuum properties at high signal to noise and moderate and echelle line_3: spectral resolution, in order to characterize the red giant winds, interactions line_4: and hot companion stars of these long period binaries. ! !end of general form text general_form_address: lname: CARPENTER fname: KENNETH mi: G. category: PI inst: NASA - GODDARD SPACE FLIGHT CENTER addr_1: CODE 681 city: GREENBELT state: MD zip: 20771 country: USA phone: 301-286-3453 ! lname: STENCEL fname: ROBERT mi: E. inst: CASA - UNIVERSITY OF COLORADO addr_1: CAMPUS BOX 391 city: BOULDER state: CO zip: 80309 country: USA phone: (303)-494-4297 ! lname: ROBINSON fname: RICHARD mi: D. inst: CSC @ NASA-GODDARD SPACE FLIGHT CENTER addr_1: CODE 681 city: GREENBELT state: MD zip: 20771 country: USA phone: (301)-286-4530 ! lname: LINSKY fname: JEFFREY mi: L. inst: JILA - UNIVERSITY OF COLORADO addr_1: CAMPUS BOX 440 city: BOULDER state: CO zip: 80309 country: USA phone: (303)-492-7838 ! ! end of general_form_address records fixed_targets: targnum: 2 name_1: HD4174 name_2: EG-AND descr_1: A,155 pos_1: RA = 0H 41M 52.700S+/- 0.3", pos_2: DEC = +40D 24' 22.17"+/- 0.3" equinox: 1950 pm_or_par: Y pos_epoch_bj: B pos_epoch_yr: 1957.87 ra_pm_val: 0.000867 ra_pm_unct: 0.000667 dec_pm_val: -0.0150 dec_pm_unct: 0.0100 rv_or_z: V=-95 comment_1: FLUXVALS ARE FOR TOP OF comment_2: EMISSION LINES IN EG AND comment_3: M2 IIIEP + SD fluxnum_1: 1 fluxval_1: V=7.4,TYPE=M2 III fluxnum_2: 2 fluxval_2: F(1400)=5.0E-12 fluxnum_3: 3 fluxval_3: F(1550)=2.5E-11 fluxnum_4: 4 fluxval_4: F(1640)=1.5E-12 ! ! end of fixed targets !
