The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Luminosity and Color Dependence and Redshift Evolution
Hong Guo, Idit Zehavi, Zheng Zheng +40
We measure the luminosity and color dependence and the redshift evolution of galaxy clustering in the Sloan Digital Sky Survey-III Baryon Oscillation Spectroscopic Survey Ninth Dat…
Molecular emission from GG Car's circumbinary disk
Michaela Kraus, Mary Oksala, Dieter Nickeler +5
The appearance of the B[e] phenomenon in evolved massive stars such as B[e] supergiants is still a mystery. While these stars are generally found to have disks that are cool and de…
The SOAR Gravitational Arc Survey - I: Survey overview and photometric catalogs
Cristina Furlanetto, Basilio X. Santiago, Martin Makler +10
We present the first results of the SOAR (Southern Astrophysical Research) Gravitational Arc Survey (SOGRAS). The survey imaged 47 clusters in two redshift intervals centered at $z…
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…
Projected Rotational Velocities and Stellar Characterization of 350 B Stars in the Nearby Galactic Disk
G. A. Bragança, S. Daflon, K. Cunha +3
Projected rotational velocities (vsini) are presented for a sample of 350 early B-type main sequence stars in the nearby Galactic disk. The stars are located within ~1.5 kpc from t…
