Fission of Transuranic Nuclei: A Potential Observational Signature in Metal-Poor Stars
This proposal aims to detect fission fragments among cadmium (Cd, element 48) abundances in stars. Transuranic elements are produced during rapid (r) neutron-capture nucleosynthesis, and models predict that many of these nuclei will fission into lighter ones listed near the middle of the periodic table. Fission models rely heavily on uncertain theoretical extrapolations from stable nuclei, which cannot be verified by current experimental techniques. Astronomical observations, on the other hand, provide a novel opportunity to constrain these models. New STIS E230H spectra (R = 114,000, S/N = 15 to 25, covering 2024-2301 A) of two well-studied UV-bright metal-poor r-process-enhanced stars will be collected. Abundances of Cd and tellurium (Te, element 52, which is not expected to show fission signatures and will be used as a control) will be derived to a precision of approximately 0.10-0.15 dex. The abundances will be compared with Cd and Te signatures previously derived for stars without high r-process enhancement, resulting in a 50% improvement in the mean abundance uncertainties. These measurements will demonstrate whether or not there are statistically significant signatures of fission fragments among the Cd and Te abundances. This new, interdisciplinary approach linking observational astronomy and theoretical nuclear physics will provide the first meaningful constraints on the fission fragment distribution for nuclei with atomic masses from 111 <= A <= 116 and 125 <= A <= 130. These spectra will also enable the detection of more than 25 other elements in each star and provide high-quality archival data for future studies of other stellar phenomena.
The goal of this observing program is to collect E230H R=114,000 spectra of two stars, CD-52 112 (2MASS J00405260-5122491) and CD-23 12296 (2MASS J15271353-2336177), with complete spectral coverage from 2024-2301 Angstroms. Both are non-variable main sequence, metal-poor Pop II stars with [Fe/H] ~ -2. Because the targets are non-variable, spectra can be collected at any time with no constraints. Observations have been grouped into 3-orbit visits to minimize overhead and maximize scheduling flexibility.
For the 3-orbit visits, there should be five exposures. Orbit 1: ACQ, ACQ/PEAK, and SCIENCE. Orbit 2: SCIENCE. Orbit 3: SCIENCE. Visits 01-10 are identical. Visits 11-20 are also identical. These two sets of visits differ only in the target star and slight variations in the "packed" exposure times.
The ICRS coordinates and proper motions are taken from Gaia DR2. Parallaxes are taken from Gaia EDR3. I have checked the target confirmation charts, and the crosshairs line up to within 1 DSS pixel of the stellar diffraction spikes on the images. This precision has been sufficient to correctly observe similar targets with the 0.2x0.09 slit in previous STIS observing runs.
The ETC target acquisition gave a WARNING MESSAGE: Partial overlap between instrument throughput band and target spectrum. Please doublecheck the wavelength range covered by the selected spectrum, and the instrument documentation for the selected filter.
^^^ I encountered this warning message previously in another cycle with a similar aperture. A 2018 email from Dan Welty, via Tricia Royle, explained it as so: "I believe that this warning is triggered when the input spectrum used for the calculation does not fully cover the wavelength range over which the filter/aperture is defined. In this case, the input spectrum goes down to about 1300 A, but the F25ND3 is defined to below 1250 A. But since both the filter/CCD transmission and the input spectrum are both rapidly declining below 1300 A, it should not be a problem for the acq." Based on this information, I have disregarded this warning message.
Operations in reduced gyro mode (RGM) should have minimal impact on this science program, except perhaps for a reduction in available observing windows.
PI Roederer has expertise in stellar abundances and has led 7 previous STIS or COS observing programs with HST. Co-Is Den Hartog and Lawler have expertise in measuring atomic data in a laboratory setting to help interpret stellar spectra. Co-Is Cowan, Holmbeck, Mumpower, Surman, and Vassh have expertise in theoretical interpretation of nucleosynthesis signatures, particularly fission. Co-Is Beers, Ezzeddine, Frebel, Hansen, Holmbeck, Placco, Sakari, and Sneden have expertise in identifying metal-poor stars, determining stellar parameters, and deriving abundances.
