abstract:

    line_1:        We propose to continue observations of a sample of late A/
    line_2:        early F dwarfs in the Pleiades, UMa and Hyades clusters,
    line_3:        and in the field, to study the inception of chromospheric
    line_4:        emission as a function of stellar temperature and age.
    line_5:        The scope of this program has decreased with time:
    line_6:        all we have time to do this cycle is alpha Aql, A7 IV-V.

  question:        3
    section:       1
    line_1:        The observation are straightforward, with no repetitions.
    line_2:        No problems are anticipated. This cycle we will use G160M
    line_3:        to obtain spectra of the C II and C IV regions, to seek
    line_4:        evidence of chromospheric emission from a reasonably hot
    line_5:        star, alpha Aql (B-V-0.22).

!

  question:        4
    section:       1
    line_1:        The chromospheric and transition region line emission
    line_2:        lies in the far UV, which is inaccessible from the ground.

!

  question:        7
    section:       1
    line_1:        The spectra will be analyzed using standard spectroscopic
    line_2:        analysis packages which we have at SUNY

!

  question:        10
    section:       1
    line_1:        SUNY will provide the data analysis capabilities for the scientific analysis.

!

  question:        12
    section:       1
    line_1:        Estimated observing time are from RPSS, with corrections
    line_2:        for spurious overheads.

!

  question:        13
    section:       1
    line_1:        We had intended to observe 24 young A/F and G dwarfs in 4
    line_2:        young clusters: alpha Per, UMa, the Pleiades, and Hyades,
    line_3:        and in the field. Our downsized program: to search for the
    line_4:        inception of solar-like chromospheres among the late A
    line_5:        stars. Alcor (A5V) was our cycle 0 target; Alpha Aql
    line_6:        (A7 IV-V) is our cycle 2 target. The cycle 3 plan will be
    line_7:        revealed later.
