We present data on 13 post-nova systems. This includes the recovery via UBVR photometry of the five post-novae X Cir, V2104 Oph, V363 Sgr, V928
Sgr and V1274 Sgr and their spectroscopic confirmation. We provide
accurate coordinates and finding charts for those objects. Additional
first-time or improved spectroscopic data are presented for V356 Aql,
V500 Aql, V604 Aql, V1370 Aql, MT Cen, V693 CrA, V697 Sco and MU Ser.
Investigating the behaviour of a few easily accessible parameters yields
(limited) information on the accretion state and the system inclination.
We predict that X Cir and V697…
There are many ways to solve the challenging problem of making a high
performance robotic observatory from scratch. The Observatorio
Astrof\'isico de Javalambre (OAJ) is a new astronomical facility located
at the Sierra de Javalambre (Teruel, Spain) whose primary role will be
to conduct all-sky astronomical surveys. The OAJ control system has been
designed under a global point of view including not only astronomical
subsystems but also infrastructure and other facilities. Three main
factors have been considered in the design of a global control system
for the robotic OAJ: quality,…
We study a hundred of galaxies from the spectroscopic Sloan Digital Sky
Survey (SDSS) with individual detections in the far-infrared Herschel
Photodetector Array Camera and Spectrometer bands (100 or 160 μm) and
in the GALEX far-ultraviolet band up to z ˜ 0.4 in the COSMOS and
Lockman Hole fields. The galaxies are divided into four spectral and
four morphological types. For the star-forming and unclassifiable
galaxies, we calculate dust extinctions from the ultraviolet (UV) slope,
the Hα/Hβ ratio and the L<SUB>IR</SUB>/L<SUB>UV</SUB> ratio.
There is a tight…
High Z materials, as possible plasma facing components for a fusion
reactor, are being re-evaluated due to their advantages connected to the
low sputtering yield and small erosion. A data base of experimental
results related to their use on present Tokamak is missing. FTU has
carried out a series of experiments with different medium and high Z
limiter materials, Ni, Mo, and W, to improve the knowledge of the plasma
behavior in these conditions. The results on plasma operation, core
parameters, impurity content, and corresponding radiation losses are
presented, and compared with those…
