My CS tells me that the warning is there because the split wavecal accuracy was tested only up to 2400 s. Any accuracy differences between 2400 s and 2690 s should be minimal. Visit 4 has already been completed. I have run all the tools multiple times. The Blue Edge of the Helium White Dwarf Instability Strip Aims: This proposal focuses on obtaining accurate temperatures and abundances for white dwarfs near the blue edge of the helium instability strip. Context: The observed location of the helium white dwarf instability strip in the temperature/log g plane is a strong indicator of convective efficiency in WD atmospheres, and by extension in all stellar envelopes. The blue edge's location was considered well established until the confirmation by Kepler K2 that the hot DB PG0112+105 is a pulsator. The empirical blue edge of the instability strip is now unknown. Uncertainties as large as 3000 K in the optical spectroscopic temperature scale for DBs presents considerable problems in accurately the location of the blue edge through optical data alone. Obtaining UV spectra and light curves of DBs near the blue edge of the DB instability strip will provide a definitive location in the temperature/log g plane for the initiation of pulsations. This result can then be used to 1) calibrate mixing length theory used in all stellar models, 2) validate 3D hydrodynamic simulations, 3) constrain contributions of different driving mechanisms initiating pulsations, and 4) improve our understanding of mixing and diffusion of different elements in white dwarf convection zones.. Methods: This proposal presents the justification for COS observations of 6 DB white dwarfs with temperatures between 35,000 and 29,000 K. The observations will determine 1) accurate temperatures, surface gravities, and chemical abundances, 2) determine if each target is pulsating and lies in the strip, and 3) determine an accurate empirical blue edge for the helium instability strip. The proposed observations will determine the temperature and photospheric composition of 5 helium atmosphere white dwarfs with temperatures near the suspected blue edge of the helium instability strip. The goal is to constrain the location of the blue edge of the instability strip. We have 5 targets: EGGR-409, SDSSJ095256.69+015407.7, SDSSJ140028.43+475644.1, SDSSJ141258.17+045602.2 and SBSS-1540+505. The observations are relatively straight forward. We have selected the gratings and central wavelengths to detect photospheric lines of hydrogen, carbon, oxygen, silicon and other elements in the spectra of the two targets. White dwarf stars are known for their nearly pure photospheres of either hydrogen or helium, at least at optical wavelengths. The UV wavelength range, however, contains numerous sensistive transitions that are important for determining trace abundances of the elements of interest. Given the limits on Lyman alpha observations with G130M, we have decided to include a hydrogen line at 1025 Angstroms. The G130M grating with a central wavelength of 1096 Angstroms will access HI 1025 Angstroms, CII 1037 Angstroms, CIII 1175 Angstroms, CI 1993 Angstroms, and Si II at 1193 Angstroms. G130M with a central wavelength of 1222 Angstroms will cover SiII 1260, 1264 Angstroms, OII 1305 Angstroms, and CII 1335 Angstroms, For 1 target (SDSSJ140028), our orbit allocation was sufficent to also include G130M 1055. The limitations of the response of G160M at certain wavelengths were not as significant to our science as first anticipated. G160M with a central wavelength of 1589 Angstroms will give detailed coverage of the important HeII 1640 line as well as SiII lines at 1533 Angstroms. With the exception SDSSJ140028, we have substituted G160M for G230L. We believe the importance of the HeII line at 1640 outweighs the low resolution wavelength coverage of G230L. Most For SDSSJ140028, our orbit allocation was sufficient to include G230L and G160M. We have not exceeded our orbital allocation and our signal to noise for other exposures remains sufficient for our science needs. Measuring the strengths of photospheric lines from different transitions such as CII and CIII can be an important diagnostic for temperature. A second method to determine temperature is these hot objects is to measure the slope of the UV continuum. G140L combined with the G130M and G160M grating observations will result in a detailed measurement of the UV flux between 916 and 2148 Angstroms. The temperature determined from these measurements will confirm the effective temperatures of the targets. We have use the COS Spectroscopy Target Acquisiton and COS Spectroscopy Exposure Time SImulators to determine our exposure times. Our targets do not exceed the brightness limits for COS, and are isolated with good coordinates. For target acquistion, we determined the time required to reach a signal to noise of at least 40. White dwarf stars are faint and can have high proper motions. GAIA has reduced this issue by determining many proper motions. However, to be safe, we will acquire our targets using ACQ/SEARCH, ACQ/PEAKXD, and ACQ/PEAKD. For our science observations, we have determined exposure times to achieve a S/N of 15-20 at a wavelength of 1150 Angstroms for the G130M grating, and a S/N of 15-20 at 1500 Angstroms for the G160M and G140L gratings. The science observations will be done in TIME-TAG mode. This will enable us to search variability. All of our targets are near the blue edge of the helium instability strip. Our goal is to determine the location of this edge. Time tagged COS observations will allow us to determine the pulsational stability of each target. The pulsations are expected to be about 10 millimagnitudes or less. Dr. Judith Provencal has experience in HST data reduction for COS, the principal instrument used in the proposed observations. Dr. Provencal also has expertise in white dwarf pulsations and specializes in helium atmosphere white dwarfs. Dr Provencal has multiple papers published on pulsating white dwarfs and data analysis from previous HST observing campaigns. Dr. Provencal will serve as teamleader in data analysis and interpretation. Dr JJ Hermes is an expert on pulsating white dwarfs, particularly specializing in K2 observations. Dr. Hermes will serve as an expert on the photometric measurements. Dr. Atsuko Nitta is an expert in white dwarf data reduction and analysis and will assist in data reduction. Dr. Michael Montgomery has expertise in computational simulations of white dwarf pulsations and white dwarf modeling which will be invaluable in interpreting the proposed data. Mr. Zachary Vanderbosch is an expert in DB pulsating white dwarfs, and will be working closely with Dr. Provencal on these observations.
