The white dwarfs stopped pulsating, as the outburst heating caused them to move out of the instability strip. These outburst events give us the unprecedented opportunity to follow the emergence of the non-radial pulsations as they re-enter the strip. Unlike single white dwarfs, where cooling takes place on thousand year timescales, the cooling rates for white dwarfs following dwarf nova outbursts are only 3-5 yrs, with Cycle 18 ideally suited to catch this transition. Our past HST observations have shown that the UV is critical to a correct temperature determination (the white dwarf dominates over the disk emission in the UV and the Ly alpha turnover provides a crucial constraint) and mode identification (the UV/optical pulsation amplitude is typically 6-17 and indicative of low order modes). We propose to use COS in TIME-TAG mode to obtain the temperatures and UV pulsation amplitudes of the 4 post-outburst systems. ------------------------------------------------------------------------------------ Observations Description ------------------------ Our primary goal is to obtain a summed spectrum with sufficient S/N to allow a temperature fit with models, with a secondary goal to obtain time-resolved light curves to detect or constrain the UV pulsation amplitude. We plan to use 2 orbits on each of the 4 objects with COS and grating G140L. We expect the white dwarfs in the 4 objects to be between 11, 000-15, 000K (we know the quiescent temperatures of V455 And and GW Lib from prior HST observations and they may be somewhat hotter post outburst than pre-outburst). We used a Hubeny (1988) model white dwarf for 12, 500K white dwarf at 100 pc as input to the 12231( 5) - 27-Jul-2011 17:43:42 - [ 2] COS ETC G140L (grating setting 1105). This provides a S/N of 22 per resolution element at 1500ĦA for 1 orbit. GW Lib is at a similar distance but has a hotter temperature so it will produce a higher S/N. We expect SDSSJ0745+45 will have a comparable (or hotter) temperature than GW Lib, but its distance is larger by a factor of 4, so the combined two orbits with some binning will be required to achieve a good temperature derivation. For V455 And, the temperature may be down to its quiescent value of 10, 500K, in which case the two orbits will provide a good temperature determination. The previous quiescent observation with STIS was done during a snapshot program with only a short 700 sec observation that extended to 1700ĦA. The better sensitivity and longer redward wavelength coverage of COS is better suited to cooler white dwarfs. In addition, the short snapshot exposure did not allow the determination of the UV pulse amplitude. With COS, the pulse amplitude will be measurable if the amplitude is large (expected for low order modes). For GW Lib, the pulsation periods evident in UV and optical at quiescence were in the 230-650s range and the optical pulsation periods of V455 And are around 340 sec. If the white dwarf driving zones are hotter than pre-outburst, the periods are expected to be shorter than quiescence once they return. Thus, 2 HST orbits (about 80 min total time) with light curves created by summing the time-tag fluxes over several hundred ĦA and several minutes should be able to detect or place limits on the UV amplitudes. The planned continuation of our ground monitoring observations will be used to delineate the optical pulse periods and amplitudes in all cases.
