14231( 3) - 09-Oct-2015 17:47:04 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 14231 Version: 3 Check-in Time: 09-Oct-2015 17:47:04 STScI Edit Number: 0 Title The First Detections of Phosphorus, Sulphur, and Zinc in a Bona-Fide Second-Generation Star ------------------------------------------------------------------------------------ Type Cycle GO 23 ------------------------------------------------------------------------------------ Investigators Contact? PI: Dr. Ian U. Roederer University of Michigan Y CoI: Dr. Vinicius Placco University of Notre Dame N CoI: Dr. Timothy C. Beers University of Notre Dame N ------------------------------------------------------------------------------------ Abstract We propose to obtain new NUV COS spectra of the bright carbon-enhanced metal-poor star BD+44 493. This extremely low-metallicity ([Fe/H] = -3.8) star exhibits the chemical signature expected for a second-generation star that formed from the metals produced by a single zero-metallicity Population III star. Our group has previously studied the detailed abundance pattern of this star from NUV and optical spectra (2300-9350 Angstroms). Now we propose to obtain new high-resolution spectra of this star extending to 1800 Angstroms. These observations would allow us to detect three elements that have not been studied previously in BD+44 493, or any other CEMP star with [Fe/H] < -4: phosphorus, sulphur, and zinc. Our proposed observations will constrain the abundances of these elements, and test the predictions of models for at least one of the likely zero-metallicity supernova progenitors that may have existed in the early Universe. ------------------------------------------------------------------------------------ Observations Description ------------------------ The goal of this program is to obtain high-resolution COS spectra of the late-G-type star BD+44 493. Three grating positions will be used: G185M, center=1913A: target S/N ~ 20/1 at 1821 Angstroms after all co-adds (12 orbits) G185M, center=1971A: target S/N ~ 40/1 at 2065 Angstroms after all co-adds (3 orbits) G225M, center=2233A: target S/N ~ 40/1 at 2130 Angstroms after all co-adds (3 orbits). I have verified the target confirmation chart for this star. -- IUR, 06 July 2015 ------------------------------------------------------------------------------------ 14231( 3) - 09-Oct-2015 17:47:04 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 BD+44-493 STAR, G III-I, HALO, RA=02H26M49.7394S +/- 0.003", J2000 V = 9.11 +/- 0.02 E(B-V) = 0.042 (low!)
