abstract:
line_1:For 2 decades the "Cepheid mass problem" has persisted: Mass
line_2:determinations from standard evolutionary tracks and those from
line_3:pulsation theory gave conflicting values. The luminosity of a Cepheid
line_4:of given mass depends sensitively on the amount of convective overshoot
line_5:above the core of the main sequence progenitor. Hence a good mass
line_6:determination for the Cepheid with known luminosity will measure the
line_7:amount of convective core overshoot. This knowledge is important for
line_8:interpretation of HR diagrams of populous clusters in the LMC and
line_9:especially for age determinations. It is also necessary for the
line_10:understanding of the mixing processes in stars.
line_11: Program 5357 obtained the GHRS spectra for this program. This is
line_12: a follow-on part 2 to obtain the calibration spectra to measure the
line_13: radial velocity of the 2 primary targets observed in 5357.

question: 3
section: 1
line_1:The purpose of this proposal is to obtain GHRS calibration spectra
line_2: on two targets. Standard GHRS spectra will be obtained after routine
line_3: onboard target acquisitions are performed. Internal wavelength
line_4: calibrations are performed in association with the external
line_5: observations.
