| 内容記述 | Radial-velocity curves for both components of the short-period, white dwarf M dwarf binary systems Case 1 and HZ 9 have been determined from 1-A-resolution spectra obtained at the MMT. The radial-velocity curves for the M dwarf components agree well with previous determinations. The new data have been used to estimate masses for the white dwarfs, yielding 0.38 solar mass for the Case 1 DA and 0.51 solar mass for the HZ 9 DA, with 1sigma uncertainties of about 0.1 solar mass. |
