Global Properties of M31's Stellar Halo from the SPLASH Survey. I. Surface Brightness Profile
Karoline M. Gilbert, Puragra Guhathakurta, Rachael L. Beaton +10
We present the surface brightness profile of M31's stellar halo out to a projected radius of 175 kpc. The surface brightness estimates are based on confirmed samples of M31 red gia…
Addressing Decadal Survey Science through Community Access to Highly Multiplexed Spectroscopy with BigBOSS on the KPNO Mayall Telescope
Caty Pilachowski, Carles Badenes, Stephen Bailey +87
This document summarizes the results of a community-based discussion of the potential science impact of the Mayall+BigBOSS highly multiplexed multi-object spectroscopic capability.…
The Space Motion of Leo I: Hubble Space Telescope Proper Motion and Implied Orbit
Sangmo Tony Sohn, Gurtina Besla, Roeland P. van der Marel +3
We present the first absolute proper motion measurement of Leo I, based on two epochs of HST ACS/WFC images separated by ~5 years. The average shift of Leo I stars with respect to…
The Milky Way's circular velocity curve between 4 and 14 kpc from APOGEE data
Jo Bovy, Carlos Allende Prieto, Timothy C. Beers +30
We measure the Milky Way's rotation curve over the Galactocentric range 4 kpc <~ R <~ 14 kpc from the first year of data from the Apache Point Observatory Galactic Evolution Experi…
Observable Signatures of Planet Accretion in Red Giant Stars I: Rapid Rotation and Light Element Replenishment
Joleen K. Carlberg, Katia Cunha, Verne V. Smith +1
The orbital angular momentum of a close-orbiting giant planet can be sufficiently large that, if transferred to the envelope of the host star during the red giant branch (RGB) evol…
Photometry of the Stellar Tidal Stream in the Halo of Messier 63
Taylor S. Chonis, David Martinez-Delgado, R. Jay Gabany +3
We present surface photometry of a giant, low surface brightness stellar arc in the halo of the nearby spiral galaxy M63 (NGC 5055) that is consistent with being a part of a stella…
