abstract:
line_1: V471 Tau is an eclipsing binary in the Hyades cluster whose components
line_2: are a DA white dwarf and a detached K2 V main-sequence star. It
line_3: presents a unique opportunity for direct determination of the mass of
line_4: a white dwarf, except that it is impossible to obtain the velocity
line_5: curve of the white dwarf from the ground because its light is swamped
line_6: by that of the K dwarf. We propose to determine its velocity curve
line_7: using the GHRS at Lyman-alpha, where the white dwarf has a strong
line_8: absorption feature, and thus obtain only the fourth fundamentally
line_9: determined mass of a white dwarf. As bonuses, our observations will
line_10: also: (1) provide constraints on the presence of photospheric metals
line_11: accreted at the white dwarf's magnetic poles from the K2 V star's
line_12: wind; (2) allow us to search for modulation of metal lines at the
line_13: 9.25-min rotation period of the white dwarf, which is expected if the
line_14: metals are concentrated at the magnetic poles; (3) measure the
line_15: gravitational redshift of the white dwarf; and (4) stringently
line_16: constrain the magnetic field strength of the white dwarf by the
line_17: presence or absence of Zeeman components of Lyman-alpha.

question: 3
section: 1
line_1: V471 Tau is an eclipsing binary containing a white dwarf (WD) and a K
line_2: dwarf (dK), with an orbital period of 12.5 hours. The WD is also known
line_3: to rotate with a period of 9.25 minutes.
line_5: In order to determine the radial-velocity curve of the white-dwarf
line_6: component, we will obtain GHRS observations centered near phases 0.25
line_7: and 0.75 of the 12.5-hour binary-star orbit. We will use the G160M
line_8: grating, which provides 34 A of coverage, at a dispersion of 0.07
line_9: A/diode, and will center the spectra at Ly-alpha. Such exposures will
line_10: cover the core and a significant portion of the wings of Ly-alpha.
line_12: We will obtain a total of four independent observations each near
line_13: phase 0.25 and near phase 0.75, for a total of eight separate
line_14: observations. Each of the eight observations will have a duration of
line_15: four white-dwarf rotation periods, for a total of 37 min.
line_17: Each of the 37-min runs will be broken into 16 individual spectra
line_18: (i.e., there will be four spectra taken per white-dwarf rotation
line_19: period), in order to allow a search for rotational modulation of any
line_20: Zeeman structure in Ly-alpha or in any photospheric metal lines. Note
line_21: that deadtime between exposures is assumed to be 20 sec. The exposure
line_22: time for each of the 16 spectra is thus 8 times 14.4 sec, which is the
line_23: step-time for our chosen step-patt and comb, or 115.2 seconds.
!
question: 3
section: 2
line_1: The observing sequence (for each of the eight independent
line_2: observations) is: (1) acquire target in LSA; (2) acquire/peakup in
line_3: SSA; (3) wavelength calibration (with no further carousel motions
line_4: during the sequence); (4) the 16 science observations covering 37 min;
line_5: (5) a final wavelength calibration.
!
question: 4
section: 1
line_1: (See Phase I proposal.)
!
question: 5
section: 1
line_1: Observations are time-critical and uninterrupted, since they must cover
line_2: specific orbital phases of the binary star. The detailed requirements
line_3: are given in the Special Requirements on the Exposure Logsheet.
line_4: DARK TIME would have been desirable to reduce the intensity of
line_5: geocoronal Lyman-alpha but we were told in Cycle 3 that this would make
line_6: the observations very difficult to schedule.
!
question: 6
section: 1
line_1: Wavelength calibrations before and after the science observations are
line_2: specified in the Exposure Logsheet.
