Investigating APOKASC Red Giant Stars with Abnormal Carbon to Nitrogen Ratios
Erica Bufanda, Jamie Tayar, Daniel Huber +2
The success of galactic archaeology and the reconstruction of the formation history of our galaxy critically relies on precise ages for large populations of stars. For evolved star…
Chemical abundances of the young inner-disk open cluster NGC 6705 observed by APOGEE: sodium-rich and not -enhanced
V. Loaiza-Tacuri, K. Cunha, D. Souto +19
Previous results in the literature have found the young inner-disk open cluster NGC 6705 to be mildly -enhanced. We examined this possibility via an independent chemical abundan…
Exploring the Origin of the Distance Bimodality of Stars in the Periphery of the Small Magellanic Cloud with APOGEE and Gaia
Andres Almeida, Steven R. Majewski, David L. Nidever +12
The Magellanic Cloud system represents a unique laboratory for study of both interacting dwarf galaxies and the ongoing process of the formation of the Milky Way and its halo. We f…
A Tale of Two Disks: Mapping the Milky Way with the Final Data Release of APOGEE
Julie Imig, Cathryn Price, Jon A. Holtzman +24
We present new maps of the Milky Way disk showing the distribution of metallicity ([Fe/H]), -element abundances ([Mg/Fe]), and stellar age, using a sample of 66,496 red giant st…
Revealing the Chemical Structure of the Magellanic Clouds with APOGEE. I. Calculating Individual Stellar Ages of RGB Stars in the Large Magellanic Cloud
Joshua T. Povick, David L. Nidever, Pol Massana +12
Stellar ages are critical for understanding the temporal evolution of a galaxy. We calculate the ages of over 6000 red giant branch stars in the Large Magellanic Cloud (LMC) observ…
Confident Detection of Doubly-Ionized Thorium in the Extreme Ap Star CPD-62 2717
S. Drew Chojnowski, Swetlana Hubrig, David L. Nidever +4
Despite the universe containing primordial thorium (Th) of sufficient abundance to appear in stellar spectra, detection of Th has to date been tentative and based on just a few wea…
