Stellar evolution through the ages: period variations in galactic RRab stars as derived from the GEOS database and TAROT telescopes
J. F. Le Borgne, A. Paschke, J. Vandenbroere +6
The theory of stellar evolution can be more closely tested if we have the opportunity to measure new quantities. Nowadays, observations of galactic RR Lyr stars are available on a…
The HELLAS2XMM survey: XI. Unveiling the nature of X-ray Bright Optically Normal Galaxies
F. Civano, M. Mignoli, A. Comastri +8
X-ray Bright Optically Normal Galaxies (XBONGs) constitute a small but not negligible fraction of hard X-ray selected sources in recent Chandra and XMM-Newton surveys. Even though…
An X-ray jet in the BL Lac S5 2007+777
R. M. Sambruna, D. Donato, C. C. Cheung +2
The BL Lac S5 2007+777 was observed by us with Chandra, to find the X-ray counterpart to its 18" radio jet, and study its structure. Indeed, a bright X-ray jet was discovered in th…
The variability plane of accreting compact objects
E. G. Koerding, S. Migliari, R. Fender +3
Recently, it has been shown that soft-state black hole X-ray binaries and active galactic nuclei populate a plane in the space defined by the black hole mass, accretion rate and ch…
The First Survey of X-ray Flares from Gamma Ray Bursts Observed by Swift: Spectral Properties and Energetics
A. D. Falcone, D. Morris, J. Racusin +12
Observations of gamma ray bursts (GRBs) with Swift produced the initially surprising result that many bursts have large X-ray flares superimposed on the underlying afterglow. The f…
A new search for planet transits in NGC 6791
M. Montalto, G. Piotto, S. Desidera +12
Context. Searching for planets in open clusters allows us to study the effects of dynamical environment on planet formation and evolution. Aims. Considering the strong dependence o…
