On the relation between Seyfert 2 accretion rate and environment at z < 0.1
Georgina V. Coldwell, Sebastian Gurovich, Jorge Diaz Tello +2
We analyse different properties of the small scale environment of Seyfert 2 for two samples selected according to the accretion rate parameter, R, from the DR7-SDSS survey. We comp…
The Angular Clustering of WISE-Selected AGN: Different Haloes for Obscured and Unobscured AGN
E. Donoso, Lin Yan, D. Stern +1
We calculate the angular correlation function for a sample of 170,000 AGN extracted from the Wide-field Infrared Survey Explorer (WISE) catalog, selected to have red mid-IR colors…
Magnetic fields of Herbig Ae/Be stars
S. Hubrig, I. Ilyin, M. Schoeller +5
We report on the status of our spectropolarimetric studies of Herbig Ae/Be stars carried out during the last years. The magnetic field geometries of these stars, investigated with…
Using the Dipolar and Quadrupolar Moments to Improve Solar-Cycle Predictions Based on the Polar Magnetic Fields
Andrés Muñoz-Jaramillo, Laura A. Balmaceda, Edward E. DeLuca
The solar cycle and its associated magnetic activity are the main drivers behind changes in the interplanetary environment and Earth's upper atmosphere (commonly referred to as spa…
Galaxy triplets in Sloan Digital Sky Survey Data Release 7: II. A connection with compact groups?
Fernanda Duplancic, Ana Laura O'Mill, Diego G. Lambas +2
We analyse a sample of 71 triplets of luminous galaxies derived from the work of O'Mill et al. (2012). We compare the properties of triplets and their members with those of control…
Milky Way Demographics with the VVV Survey II. Color Transformations and Near-Infrared Photometry for 136 Million Stars in the Southern Galactic Disk
M. Soto, R. Barba, G. Gunthardt +18
The new multi-epoch near-infrared VVV survey (VISTA Variables in the Via Lactea) is sampling 562 sq. deg of the Galactic bulge and adjacent regions of the disk. Accurate astrometry…
Studying the kinematics of the giant star-forming region 30 Doradus. I. The data
S. Torres-Flores, R. Barbá, J. Maíz Apellániz +4
We present high-quality VLT-FLAMES optical spectroscopy of the nebular gas in the giant star-forming region 30 Doradus. In this paper, the first of a series, we introduce our obser…
Solar Cycle Propagation, Memory, and Prediction: Insights from a Century of Magnetic Proxies
Andrés Muñoz-Jaramillo, María Dasi-Espuig, Laura A. Balmaceda +1
The solar cycle and its associated magnetic activity are the main drivers behind changes in the interplanetary environment and the Earth's upper atmosphere (commonly referred to as…
The new Wolf-Rayet binary system WR62a
A. Collado, R. Gamen, R. H. Barbá
Context. A significant number of the Wolf-Rayet stars seem to be binary or multiple systems, but the nature of many of them is still unknown. Dedicated monitoring of WR stars favou…
Chemical-potential route for multicomponent fluids
Andrés Santos, René D. Rohrmann
The chemical potentials of multicomponent fluids are derived in terms of the pair correlation functions for arbitrary number of components, interaction potentials, and dimensionali…
Chemical surface inhomogeneities in late B-type stars with Hg and Mn peculiarity I Spot evolution in HD 11753 on short and long time scales
H. Korhonen, J. F. Gonzalez, M. Briquet +7
Aims: Time series of high-resolution spectra of the late B-type star HD 11753 exhibiting HgMn chemical peculiarity are used to study the surface distribution of different chemical…
The Top Ten Spitzer YSOs in 30 Doradus
Nolan R. Walborn, Rodolfo H. Barba, Marta M. Sewilo
The most luminous Spitzer point sources in the 30 Doradus triggered second generation are investigated coherently in the 3-8 micron region. Remarkable diversity and complexity in t…
Exploring the origin of magnetic fields in massive stars: II. New magnetic field measurements in cluster and field stars
S. Hubrig, M. Schoeller, I. Ilyin +7
Theories on the origin of magnetic fields in massive stars remain poorly developed, because the properties of their magnetic field as function of stellar parameters could not yet b…
