Very Efficient Methods for Multilevel Radiative Transfer in Atomic and Molecular Lines
A. Asensio Ramos, J. Trujillo Bueno
The development of fast numerical methods for multilevel radiative transfer (RT) applications often leads to important breakthroughs in astrophysics, because they allow the investi…
Oxygen abundances in planet-harbouring stars. Comparison of different abundance indicators
A. Ecuvillon, G. Israelian, N. C. Santos +3
We present a detailed and uniform study of oxygen abundances in 155 solar type stars, 96 of which are planet hosts and 59 of which form part of a volume-limited comparison sample w…
Gas and dust properties in the afterglow spectra of GRB 050730
R. L. C. Starling, P. M. Vreeswijk, S. L. Ellison +9
We present early WHT ISIS optical spectroscopy of the afterglow of gamma-ray burst GRB 050730. The spectrum shows a DLA system with the highest measured hydrogen column to date: N(…
Infrared luminosity functions from the Chandra Deep Field South : the Spitzer view on the history of dusty star formation at 0<z<1
E. Le Floc'h, C. Papovich, H. Dole +14
We analyze a sample of ~2600 MIPS/Spitzer 24mic sources brighter than ~80muJy and located in the Chandra Deep Field South to characterize the evolution of the comoving infrared (IR…
Observation and modeling of anomalous CN polarization profiles produced by the molecular Paschen-Back effect in sunspots
A. Asensio Ramos, J. Trujillo Bueno, M. Collados
We report novel spectropolarimetric observations of sunspots carried out with the Tenerife Infrared Polarimeter (TIP) in a near-IR spectral region around 15410 A, which is known to…
Dichroic Masers due to Radiation Anisotropy and the Influence of the Hanle Effect on the Circumstellar SiO Polarization
A. Asensio Ramos, E. Landi Degl'Innocenti, J. Trujillo Bueno
The theory of the generation and transfer of polarized radiation, mainly developed for interpreting solar spectropolarimetric observations, allows to reconsider, in a more rigorous…
