Model calculations show that these stars emit most of their light in the UV part of the electromagnetic spectrum and that an accurate determination of the flux in this region is crucial for an accurate determination of the atmospheric parameters. It will also provide a unique opportunity to test the atomic data and broadening theory in stellar conditions never met before. This will play a primordial role in our path to understand the origin of these objects as well to obtain a better understanding of the evolution of stars in general. The principal objective we hope to achieve with these observations are 1) obtain accurate surface gravity/mass for these stars, 2) constrain/determine the abundance of other elements (O, He, Mg, Ne etc.), especially oxygen, 3) verify the accuracy of the various theoretical atomic data used in the model calculations, 4) understand the origin and evolution of carbon atmosphere white dwarfs, in particular whether progenitor stars as massive as 10.5 solar masses can produce white dwarfs, rather than supernovae. We propose to observe 5 objects chosen carefully to cover the range of observed properties among carbon atmosphere white dwarfs (effective temperature, surface gravity, abundance of hydrogen/helium and magnetic field).
Our goal is to obtain an almost complete spectral energy distribution covering ~1200 to 3000 \AA. This would allow to nicely probe the short wavelength region where the flux is starting to rise as well as the region where most of the flux emerges (see Fig. 2). Since most of the carbon lines that dominate the spectra are very broad, low resolution observations with the FUV G140L and NUV G230L gratings will be used. To cover the most of the NUV region, we would use the G230L grating with three different nominal wavelength setting of respectively 2635, 2950 and 3360 \AA. For the G140L grating, the nominal wavelength setting will be at 1230 \AA. Below we present our choice of objects (as well as justification for each of them), the exposure time and number of orbits needed to achive S/N = 20 or more at 1400, 2600 1850 and 2250 \AA~(these wavelengths correspond to a continuum region of the spectrum for each of the setting described above). Since our objects are relatively far (see Fig. 1), we do the calculation by assuming the full correction for interstellar extinction, as given by the value of E(B-V) on each line of sight from the maps of Schlegel et al. (1998). In some cases, this is probably overcorrecting but since we do not really have a way to know the real value, we assume the worst case scenario. We estimate this program will necessitate a total of thirty three orbits, also allowing for improvement on S/N when completing the respective orbits. These objects were chosen to cover the range of observed properties in our sample (effective temperature, surface gravity, hydrogen/helium abundance, and magnetic field). 1 SDSS J142625.70+575218.4: This star is a very important object since it is the only one that shows pulsations. Asteroseismology studies require accurate atmospheric parameters (T_eff and log g) to be able to interpret correctly the pulsations and perhaps determine if the core is made of C and O or O-Mg-Ne. With the help of the COS ETC and using our model fit of this star (Dufour et al. 2008) normalized at the g band, we obtain exposure time of 14,094s for G140L and 7661, 4074 and 4267s for the three G230L settings. The corresponding buffer times are all much longer than exposure time so we take the later value. It thus requires 12 orbits. 2 SDSS J010647.92+151327.8: This is the only object in our sample to show the HeI 4471 line. It is also the hottest known carbon atmosphere white dwarf and thus a large fraction of the flux should be in the UV. We estimate exposure time of 1835s for G140L and 6457 2503 and 3234s for the three G230L settings. The corresponding buffer times are much longer than exposure time so we take the later value. It thus requires 7 orbits. 3 SDSS J115305.54+005646.2: This star is a typical case among the nine carbon atmosphere white dwarfs discovered so far. Optical spectra show no trace of either hydrogen or helium. We estimate exposure time of 2630s for G140L and 6218, 2567 and 2929s for the three G230L settings. The corresponding buffer times are much longer than exposure time so we take the later value. It thus requires 6 orbits. 4 SDSS J133710.19+002643.7: This object is very similar to SDSS J115305.54+005646.2 with the exeption that it has a trace of hydrogen (see Hbeta). We estimate exposure time of 2480s for G140L and 5229, 2228 and 2542s for the three G230L settings. The corresponding buffer times are all much longer than exposure time so we take the later value. It thus requires 5 orbits. 5 SDSS J220029.09-074121.5: This is the brightest object in our sample. The CII line near 4370 is abnormally broad, suggesting that a weak magnetic field slightly splits the line into three unresolved componants. We estimate exposure time of 1024s for G140L and 2121, 928 and 1078s for the three G230L settings. The corresponding buffer times are all much longer the exposure time so we take the later value. It thus require 4 orbits.
