A study of the galaxy redshift distribution toward the cosmic microwave background cold spot in the Corona Borealis supercluster
Ricardo Génova-Santos, Carmen P. Padilla-Torres, José Alberto Rubiño-Martín +2
We present a study of the spatial and redshift distributions of Sloan Digital Sky Survey (SDSS) galaxies toward the position of CrB-H, a very deep and extended decrement in the Cos…
CARMENES: Calar Alto high-Resolution search for M dwarfs with Exo-earths with a Near-infrared Echelle Spectrograph
A. Quirrenbach, P. J. Amado, H. Mandel +55
CARMENES, Calar Alto high-Resolution search for M dwarfs with Exo-earths with a Near-infrared Echelle Spectrograph, is a study for a next-generation instrument for the 3.5m Calar A…
Enhanced lithium depletion in Sun-like stars with orbiting planets
Garik Israelian, Elisa Delgado Mena, Nuno Santos +6
The surface abundance of lithium on the Sun is 140 times less than protosolar, yet the temperature at the base of the surface convective zone is not hot enough to burn Li. A large…
The Chemical Composition of Cernis 52 (BD+31 640)
J. I. Gonzalez Hernandez, S. Iglesias-Groth, R. Rebolo +3
We present an abundance analysis of the star Cernis 52 in whose spectrum we recently reported the napthalene cation in absorption at 6707.4 Å. This star is on a line of sight to th…
On the mass of the neutron star in Cyg X-2
J. Casares, J. I. Gonzalez Hernandez, G. Israelian +1
We present new high resolution spectroscopy of the low mass X-ray binary Cyg X-2 which enables us to refine the orbital solution and rotational broadening of the donor star. In con…
VSA Observations of the Anomalous Microwave Emission in the Perseus Region
Christopher T. Tibbs, Robert A. Watson, Clive Dickinson +13
The dust feature G159.6--18.5 in the Perseus region has previously been observed with the COSMOSOMAS experiment \citep{Watson:05} on angular scales of 1, and wa…
