Quantum phase transitions for an integrable quantum Rabi-like model with two interacting qubits
Roberto Grimaudo, Antonio S. M. de Castro, Antonino Messina +2
A two-interacting-qubit quantum Rabi-like model with vanishing transverse fields on the qubit-pair is studied. Independently of the coupling regime, this model can be exactly and u…
Evolution of Earth-like extended exospheres orbiting solar-like stars
Ada Canet, Ana Inés Gómez de Castro
Recent observations of the Earth's exosphere revealed the presence of an extended hydrogenic component that could reach distances beyond 40 planetary radii. Detection of similar ex…
Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…
Interstellar extinction in Orion. Variation of the strength of the UV bump across the complex
L. Beitia-Antero, Ana I. Gómez de Castro
There is growing observational evidence of dust coagulation in the dense filaments within molecular clouds. Infrared observations show that the dust grains size distribution gets s…
A data base of synthetic photometry in the GALEX ultraviolet bands for the stellar sources observed with the International Ultraviolet Explorer
Leire Beitia-Antero, Ana I. Gomez de Castro
The Galaxy Evolution Explorer (GALEX) has produced the largest photometric catalogue of ultraviolet (UV) sources. As such, it has defined the new standard bands for UV photometry:…
Protoplanetary disk shadowing by gas infalling onto the young star AK Sco
Ana I. Gomez de Castro, Robert O. P. Loyd, Kevin France +2
Young solar-type stars grow through the accretion of material from the circumstellar disk during pre-main sequence (PMS) evolution. The ultraviolet radiation generated in this proc…
The simplest example of the use of the method of images
Antonio S. de Castro
It is shown that the system consisting of two infinite and parallel planes, one of them a conductor, and the other an insulator with a uniform distribution of charges, is the simpl…
Constraints to the magnetospheric properties of T Tauri stars. I. The C II], Fe II] and Si II] ultraviolet features
Fatima Lopez-Martinez, Ana Ines Gomez de Castro
The C II] feature at ~2325 Angstrom is very prominent in the spectra of T Tauri stars (TTSs). This feature is a quintuplet of semiforbidden transitions excited at electron temperat…
Building galaxies, stars, planets and the ingredients for life between the stars. A scientific proposal for a European Ultraviolet-Visible Observatory (EUVO)
Ana I. Gómez de Castro, Thierry Appourchaux, Martin Barstow +36
The growth of luminous structures and the building blocks of life in the Universe began as primordial gas was processed in stars and mixed at galactic scales. The mechanisms respon…
Evidence of hot high velocity photoionized plasma falling on actively accreting T-Tauri Stars
Ana I Gomez de Castro
The HeII (1640 A) line and the resonance doublet of NV (UV1) provide a good diagnostic tool to constrain the excitation mechanism of hot (Te>40,000K) atmospheric/magnetospheric pla…
Mesoscopic Hydro-Thermodynamics of Phonons
A. R. Vasconcellos, A. R. B. Castro, C. A. B. Silva +1
A generalized Hydrodynamics, referred to as Mesoscopic Hydro-Thermodynamics, of phonons in semiconductors is presented. It involves the descriptions of the motion of the quasi-part…
On the source of dense outflows from T Tauri Stars. and III. Winds driven from the star-disc shear layer
Ana I. Gomez de Castro, Brigitta von Rekowski
Ultraviolet observations of classical T Tauri Stars (cTTSs) have shown that there is a hot (Te ~ 80,000 K) and dense (ne ~ 1e10 cm-3) component associated with the large scale jet.…
AK Sco, first detection of a highly disturbed atmosphere in a pre-main sequence close binary
Ana I. Gomez de Castro
AK Sco is a unique source: a ~10 Myrs old pre-main sequence spectroscopic binary composed of two nearly equal F5 stars that at periastron are separated by barely eleven stellar rad…
