The purpose is to understand the physics of these fluorescent line_4: processes. ! ! end of abstract general_form_proposers: lname: LINSKY fname: JEFFREY mi: L. inst: COLORADO, UNIVERSITY OF country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: This program involves HRS observations of one star (Arcturus) at several line_2: grating positions. Since this program requires the observations of a related line_3: GTO program "Search for hot plasmas in the Outer Atmospheres of K Giants" and line_4: the star is probably variable, I have lumped the two observing programs line_5: together under this program. ! question: 6 section: 1 line_1: Because the emission line fluxes from this star are probably variable, we line_2: request that the observations be obtained all at one time with as few line_3: interruptions as possible. ! question: 7 section: 1 line_1: We have developed radiative transfer computer codes to study the proposed line_2: fluorescent processes. ! question: 10 section: 1 line_1: Radiative transfer computer codes and Postdoctoral Research Associates. ! question: 12 section: 1 line_1: The total observing time includes overhead of 495 seconds. ! question: 13 section: 1 line_1: We propose to study the formation of emission lines of CO, H2, SI, and other line_2: species that are pumped by bright chromospheric emission lines like Lyman alpha line_3: and the OI resonance lines. The star Arcturus (K2 III) will be studied in line_4: detail as a prototype of K giants in which these fluorescent processes likely line_5: occur. ! !end of general form text general_form_address: lname: LINSKY fname: JEFFREY mi: L. category: PI inst: JILA, UNIVERSITY OF COLORADO addr_1: CAMPUS BOX 440 city: BOULDER state: CO zip: 80309 country: USA phone: (303) 492-7838 telex: 755842 JILA ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: HD124897 name_2: ALPHA-BOO descr_1: K2 III STAR.
