Chemical Analysis of the Ultra-Faint Dwarf Galaxy Grus~II. Signature of high-mass stellar nucleosynthesis
T. T. Hansen, J. L. Marshall, J. D. Simon +59
We present a detailed abundance analysis of the three brightest member stars at the top of the giant branch of the ultra-faint dwarf galaxy Grus~II. All stars exhibit a higher than…
Chemical Abundance Analysis of Tucana III, the Second -process Enhanced Ultra-Faint Dwarf Galaxy
J. L. Marshall, T. Hansen, J. D. Simon +56
We present a chemical abundance analysis of four additional confirmed member stars of Tucana III, a Milky Way satellite galaxy candidate in the process of being tidally disrupted a…
New Science, New Media: An Assessment of the Online Education and Public Outreach Initiatives of The Dark Energy Survey
R. C. Wolf, A. K. Romer, B. Nord +25
As large-scale international collaborations become the standard for astronomy research, a wealth of opportunities have emerged to create innovative education and public outreach (E…
Why is the Main Sequence of NGC 2482 So Fat?
Kevin Krisciunas, Nicholas B. Suntzeff, Daniel Q. Nagasawa +3
We present the results of high resolution spectra of seven stars in the field of NGC 2482, an open star cluster of age 447 Myr. We confirm the previously published values of the ra…
Chemical Abundance Analysis of Three -Poor, Metal-Poor Stars in the Ultra-Faint Dwarf Galaxy Horologium I
D. Q. Nagasawa, J. L. Marshall, J. D. Simon +68
We present chemical abundance measurements of three stars in the ultra-faint dwarf galaxy Horologium I, a Milky Way satellite discovered by the Dark Energy Survey. Using high resol…
An R-process enhanced star in the dwarf galaxy Tucana III
T. T. Hansen, J. D. Simon, J. L. Marshall +48
Chemically peculiar stars in dwarf galaxies provide a window for exploring the birth environment of stars with varying chemical enrichment. We present a chemical abundance analysis…
