Chemical abundances of hydrostatic and explosive alpha-elements in Sagittarius stream stars
Jeffrey L. Carlin, Allyson A. Sheffield, Katia Cunha +1
We analyze chemical abundances of stars in the Sagittarius (Sgr) tidal stream using high-resolution Gemini+GRACES spectra of 42 members of the highest surface brightness portions o…
Spectroscopic Follow-Up of the Hercules Aquila Cloud
Iulia T. Simion, Vasily Belokurov, Sergey E. Koposov +2
We designed a follow-up program to find the spectroscopic properties of the Hercules-Aquila Cloud (HAC) and test scenarios for its formation. We measured the radial velocities (RVs…
Two chemically similar stellar overdensities on opposite sides of the plane of the Galaxy
Maria Bergemann, Branimir Sesar, Judith G. Cohen +9
Our Galaxy is thought to have undergone an active evolutionary history dominated by star formation, the accretion of cold gas, and, in particular, mergers up to 10 gigayear ago. Th…
Graphene Cantilever Under Casimir Force
Amel Derras-Chouk, Eugene Chudnovsky, Dmitry Garanin +1
Stability of graphene cantilever under Casimir attraction to an underlying conductor is investigated. The dependence of the instability threshold on temperature and flexural rigidi…
A Disk Origin for the Monoceros Ring and A13 Stellar Overdensities
Allyson A. Sheffield, Adrian M. Price-Whelan, Anastasios Tzanidakis +3
The Monoceros Ring (also known as the Galactic Anticenter Stellar Structure) and A13 are stellar overdensities at estimated heliocentric distances of kpc and 15 kpc obs…
