A topology for the penumbral magnetic fields
J. Sanchez Almeida
We describe a scenario for the sunspot magnetic field topology that may account for recent observations of upflows and downflows in penumbrae. According to our conjecture, short na…
A study of binary constraints for seismology of delta Scuti stars
Orlagh L. Creevey
Seismology of single delta Scuti stars has mainly been inhibited by failing to detect many of the theoretically predicted pulsation modes, resulting in difficulties with mode ident…
Astronomical site selection: On the use of satellite data for aerosol content monitoring
A. M. Varela, C. Bertolin, C. Muñoz-Tuñón +2
The main goal of this work is the analysis of new approaches to the study of the properties of astronomical sites. In particular, satellite data measuring aerosols have recently be…
Discovery of a very high energy gamma-ray signal from the 3C 66A/B region
MAGIC Collaboration, E. Aliu
The MAGIC telescope observed the region around the distant blazar 3C 66A for 54.2 h in 2007 August-December. The observations resulted in the discovery of a gamma-ray source at ene…
The long Galactic bar as seen by UKIDSS Galactic Plane Survey
A. Cabrera-Lavers, C. Gonzalez-Fernandez, F. Garzon +2
Over the last decade there have been a series of results supporting the hypothesis of the existence of a long thin bar in the Milky Way with a half-length of 4.5 kpc and a position…
Variations of the solar granulation motions with height using the GOLF/SoHO experiment
S. Lefebvre, R. A. Garcia, S. J. Jimenez-Reyes +2
Below 1 mHz, the power spectrum of helioseismic velocity measurements is dominated by the spectrum of convective motions (granulation and supergranulation) making it difficult to d…
