Given the difficulty in directly determining prominence physical parameters from observations, prominence seismology stands as an alternative method to probe...
Prompt Comparison of Data for Optical Transients of Gamma-Ray Bursts
The prompt information given by the GRB Coordinates Network (GCN) differs very much for different GRBs. We compare the optical magnitudes quoted in GCNs for...
Propagating Waves Transverse to the Magnetic Field in a Solar Prominence
We have observed a quiescent prominence with the Hinode Solar Optical Telescope (SOT, in Ca II and H-alpha lines), Sacramento Peak Observatory (in H-alpha, H...
Propagating waves transverse to the magnetic field in a solar prominence
We have observed a quiescent prominence with the Hinode Solar Optical Telescope (SOT) (Ca II and Hα lines), Sacramento Peak Dunn Solar Telescope using the...
Propagation experiments in the near infrared along a 150-km path and from stars in the Canarian archipelago
Within the framework of the European Space Agency (ESA) SILEX project, aimed at experimentally demonstrating the feasibility of inter-satellite optical...
Propagation statistics of ground-satellite optical links with different turbulence conditions
The European Space Agency (ESA) geostationary data-relay satellite ARTEMIS started its operation in February 2003, after reaching its final position in the...
Proper handling of random errors and distortions in astronomical data analysis
The aim of a data reduction process is to minimize the influence of data acquisition imperfections on the estimation of the desired astronomical quantity. For...
Proper motion Pleiades candidate L-type brown dwarfs
We present results of an optical and near-infrared (IR) 1.8 deg2 survey in the Pleiades open cluster to search for substellar objects. From optical I-band...
