Evidence of Fanning in the Ophiuchus Stream
B. Sesar, A. M. Price-Whelan, J. G. Cohen +11
The Ophiuchus stellar stream presents a dynamical puzzle: its old stellar populations ( Gyr) cannot be reconciled with (1) its orbit in a simple model for the Milky Way po…
The Time Domain Spectroscopic Survey: Variable Object Selection and Anticipated Results
Eric Morganson, Paul J. Green, Scott F. Anderson +37
We present the selection algorithm and anticipated results for the Time Domain Spectroscopic Survey (TDSS). TDSS is an SDSS-IV eBOSS subproject that will provide initial identifica…
The fastest unbound star in our Galaxy ejected by a thermonuclear supernova
S. Geier, F. Fürst, E. Ziegerer +17
Hypervelocity stars (HVS) travel with velocities so high, that they exceed the escape velocity of the Galaxy. Several acceleration mechanisms have been discussed. Only one HVS (US…
The Nature and Orbit of the Ophiuchus Stream
B. Sesar, J. Bovy, E. J. Bernard +20
The Ophiuchus stream is a recently discovered stellar tidal stream in the Milky Way. We present high-quality spectroscopic data for 14 stream member stars obtained using the Keck a…
